TEXTUAL-CONVENTION

The rate of traffic. The units are specified by a multiplier attribute, DataRateUnitSetting, as bits per second (bps), kilobits per second (kbps), megabits per second (mbps), or gigabits per second (gbps). Kilobits per second is measured as 1,000 bits per second. Megabits per second is measured as 1 million bits per second. Gigabits per second is measured as 1 billion bits per second.

TEXTUAL-CONVENTION

The base unit for traffic rate parameters. The value of this data type allows for their interpretation in units of Bps, Kbps, Mbps or Gbps. The enumeration starts from 0 to match corresponding DOCSIS protocol TLV values. Kilobits per second is measured as 1,000 bits per second. Megabits per second is measured as 1 million bits per second. Gigabits per second is measured as 1 billion bits per second.

TEXTUAL-CONVENTION

The scheduling service provided by a CMTS for an upstream Service Flow. If the parameter is omitted from an upstream QOS Parameter Set, this object takes the value of bestEffort (2). This parameter must be reported as undefined (1) for downstream QOS Parameter Sets.

OBJECT-IDENTITY

OBJECT-TYPE

This object describes the packet classification configured on the CM or CMTS. The model is that a packet either received as input from an interface or transmitted for output on an interface may be compared against an ordered list of rules pertaining to the packet contents. Each rule is an instance of this object. A matching rule provides a Service Flow ID to which the packet is classified. All rules need to match for a packet to match a classifier. The attributes in this row correspond to a set of Classifier Encoding parameters in a DOCSIS MAC management message. The BitMap attribute indicates which particular parameters were present in the classifier as signaled in the DOCSIS message. If the referenced parameter was not present in the signaled Classifier, the corresponding attribute in this instance reports a value as specified by that attribute description.

The IP TOS octet as originally defined in RFC 791 has been superseded by the 6-bit Differentiated Services Field (DSField, RFC 3260) and the 2-bit Explicit Congestion Notification Field (ECN field, RFC 3168). This object is defined as an 8-bit octet per the DOCSIS Specification for packet classification.

OBJECT-TYPE

This attribute indicates the value of the IP Protocol field required for IP packets to match this rule. The value 256 matches traffic with any IP Protocol value.

OBJECT-TYPE

This attribute indicates the format of the layer 3 protocol ID in the Ethernet packet. A value of 'none' means that the rule does not use the layer 3 protocol type as a matching criteria. A value of 'ethertype' means that the rule applies only to frames that contain an EtherType value. Ethertype values are contained in packets using the Dec-Intel-Xerox (DIX) encapsulation or the RFC1042 Sub-Network Access Protocol (SNAP) encapsulation formats. A value of 'dsap' means that the rule applies only to frames using the IEEE802.3 encapsulation format with a Destination Service Access Point (DSAP) other than 0xAA (which is reserved for SNAP). A value of 'mac' means that the rule applies only to MAC management messages for MAC management messages. A value of 'all' means that the rule matches all Ethernet packets. If the Ethernet frame contains an 802.1P/Q Tag header (i.e., EtherType 0x8100), this attribute applies to the embedded EtherType field within the 802.1P/Q header. If the referenced parameter is not present in a classifier, this attribute reports the value of 0.

OBJECT-TYPE

If EnetProtocolType is 'none', this attribute is ignored when considering whether a packet matches the current rule. If EnetProtocolType is 'ethertype', this attribute gives the 16-bit value of the EtherType that the packet must match in order to match the rule. If EnetProtocolType is 'dsap', the lower 8 bits of this attribute's value must match the DSAP byte of the packet in order to match the rule. If EnetProtocolType is 'mac', the lower 8 bits of this attribute's value represent a lower bound (inclusive) of MAC management message type codes matched, and the upper 8 bits represent the upper bound (inclusive) of matched MAC message type codes. Certain message type codes are excluded from matching, as specified in the reference. If the Ethernet frame contains an 802.1P/Q Tag header (i.e., EtherType 0x8100), this attribute applies to the embedded EtherType field within the 802.1P/Q header. If the referenced parameter is not present in the classifier, the value of this attribute is reported as 0.

OBJECT-TYPE

This attribute applies only to Ethernet frames using the 802.1P/Q tag header (indicated with EtherType 0x8100). Such frames include a 16-bit Tag that contains a 3-bit Priority field and a 12-bit VLAN number. Tagged Ethernet packets must have a 3-bit Priority field within the range of PriLow to PriHigh in order to match this rule. If the referenced parameter is not present in the classifier, the value of this attribute is reported as 0.

OBJECT-TYPE

This attribute applies only to Ethernet frames using the 802.1P/Qtag header (indicated with EtherType 0x8100). Such frames include a 16-bit Tag that contains a 3-bit Priority field and a 12-bit VLAN number. Tagged Ethernet packets must have a 3-bit Priority field within the range of PriLow to PriHigh in order to match this rule. If the referenced parameter is not present in the classifier, the value of this attribute is reported as 7.

OBJECT-TYPE

This attribute applies only to Ethernet frames using the 802.1P/Q tag header. Tagged packets must have a VLAN Identifier that matches the value in order to match the rule. If the referenced parameter is not present in the classifier, the value of this attribute is reported as 0.

OBJECT-TYPE

This attribute indicates whether or not the classifier is enabled to classify packets to a Service Flow. If the referenced parameter is not present in the classifier, the value of this attribute is reported as inactive(2).

OBJECT-TYPE

This attribute counts the number of packets that have been classified using this entry. This includes all packets delivered to a Service Flow maximum rate policing function, whether or not that function drops the packets. This counter's last discontinuity is the ifCounterDiscontinuityTime for the same ifIndex that indexes this attribute.

OBJECT-TYPE

This attribute indicates which parameter encodings were actually present in the DOCSIS packet classifier encoding signaled in the DOCSIS message that created or modified the classifier. Note that Dynamic Service Change messages have replace semantics, so that all non-default parameters must be present whether the classifier is being created or changed. A bit of this attribute is set to 1 if the parameter indicated by the comment was present in the classifier encoding, and to 0 otherwise. Note that BITS are encoded most significant bit first, so that if, for example, bits 6 and 7 are set, this attribute is encoded as the octet string '030000'H.

OBJECT-TYPE

This attribute indicates the type of the Internet address for docsQosPktClassIpSourceAddr, docsQosPktClassIpSourceMask, docsQosPktClassDestAddr, and docsQosPktClassIpDestMask. If the referenced parameter is not present in a classifier, this object reports the value of 'ipv4'. Note that this attribute does not meet the requirements of RFC 3291 and will generate smilint warnings. RFC 3291 states that a separate InetAddressType value must be specified for the source destination of an IP address. It was determined that separate InetAddressType values were not necessary for the docsQosPktClassIpSourceAddr and docsQosPktClassDestAddr attributes as other methods of uniquely identifying an IP flow are available.

OBJECT-TYPE

This attribute represents the Flow Label field in the IPv6 header to be matched by the classifier. The value zero indicates that the Flow Label is not specified as part of the classifier and is not matched against the packets.

OBJECT-TYPE

This attribute represents a bit-mask of the CM in-bound interfaces to which this classifier applies. This attribute only applies to QOS upstream Classifiers and upstream Drop Classifiers. For QOS downstream classifiers this object reports the zero-length string.

OBJECT-TYPE

This attribute specifies the high-end inclusive range of the ICMP type numbers to which a packet is compared. If the referenced parameter is not present in a classifier, this attribute reports the value of 255.

OBJECT-TYPE

This object describes the set of QOS parameters defined in a managed device. DOCSIS 1.0 COS service profiles are not represented in this object. Each row corresponds to a DOCSIS QOS Parameter Set as signaled via DOCSIS MAC management messages. Each attribute of an instance of this object corresponds to one or part of one Service Flow Encoding. The BitMap attribute indicates which particular parameters were signaled in the original registration or dynamic service request message that created the QOS Parameter Set. In many cases, even if a QOS Parameter Set parameter was not signaled, the DOCSIS specification calls for a default value to be used. That default value is reported as the value of the corresponding attribute in this object instance. Many attributes are not applicable, depending on the Service Flow direction, upstream scheduling type or Service Flow bonding configuration. The attribute value reported in this case is specified by those attributes descriptions. For CM devices supporting the ParamSet object, the CM reports only the active service flow parameter set values. The CM may report the admitted and provisioned service flow parameter sets. Beginning with CCAP OSSI specification I15, CCAP reporting of admitted and provisioned service flow parameter sets becomes optional, as a means of reducing the volume of information reported by the CCAP. The CCAP reports the active service flow parameter set values. The CCAP may report the admitted and provisioned service flow parameter sets.

OBJECT-TYPE

The conceptual row of docsQosParamSetTable. The ifIndex key corresponds to the MAC Domain interface of the service flow of this Qos Param Set.

This attribute represents the Service Class Name from which the parameter set values were derived. If the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, this attribute returns the zero-length string.

OBJECT-TYPE

This attribute represents the relative priority of a Service Flow. Higher numbers indicate higher priority. This priority should only be used to differentiate Service Flow from identical parameter sets. This attribute returns 0 if the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set or if the parameter is not applicable.

OBJECT-TYPE

This attribute represents the 4 byte value of the maximum sustained traffic rate allowed for this Service Flow. It represents all MAC frame data PDUs from the bytes following the MAC header HCS to the end of the CRC. The number of bytes forwarded is limited during any time interval. The value 0 means no maximum traffic rate is enforced. The value of the DataRateUnitSetting attribute defines the units of MaxTrafficRate. This attribute applies to both upstream and downstream Service Flows. This attribute returns 0 if the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, or if the parameter is not applicable.

OBJECT-TYPE

This attribute specifies the token bucket size in bytes for this parameter set. The value is calculated from the byte following the MAC header HCS to the end of the CRC. This object is applied in conjunction with MaxTrafficRate to calculate maximum sustained traffic rate. If the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, this attribute returns 3044 for scheduling types 'bestEffort', 'nonRealTimePollingService' and 'realTimePollingService'. If this parameter is not applicable, it is reported as 0.

OBJECT-TYPE

This attribute represents the 4 byte value of the guaranteed minimum rate allowed for this Service Flow. The value is calculated from the byte following the MAC header HCS to the end of the CRC. The value of 0 indicates that no bandwidth is reserved. If the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, this attribute returns 0. If the parameter is not applicable, it is reported as 0. The value of the DataRateUnitSetting attribute defines the units of MinReservedRate.

OBJECT-TYPE

This attribute specifies an assumed minimum packet size in bytes for which the MinReservedRate will be provided. The value is calculated from the byte following the MAC header HCS to the end of the CRC. If the referenced parameter is omitted from a DOCSIS QOS parameter set, the used and reported value is CMTS implementation and the CM reports a value of 0. If the referenced parameter is not applicable to the direction or scheduling type of the Service Flow, both CMTS and CM report the value 0.

OBJECT-TYPE

This attribute specifies the maximum duration in seconds that resources remain unused on an active service flow before the CMTS signals that both the active and admitted parameter sets are null. The value 0 signifies an infinite amount of time. If the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, this attribute returns 0.

OBJECT-TYPE

This attribute specifies the maximum duration in seconds that resources remain in admitted state before resources must be released. The value of 0 signifies an infinite amount of time. If the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, this attribute returns 200.

OBJECT-TYPE

This attribute specifies the maximum concatenated burst in bytes that an upstream Service Flow is allowed. The value is calculated from the FC byte of the Concatenation MAC Header to the last CRC byte of the last concatenated MAC frame, inclusive. The value of 0 specifies no maximum burst. If the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, this attribute returns the value of 1522 for scheduling types 'bestEffort', 'nonRealTimePollingService', and 'realTimePollingService'. If the parameter is not applicable, it is reported as 0.

OBJECT-TYPE

This attribute specifies the upstream scheduling service used for upstream Service Flow. If the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set of an upstream Service Flow, this attribute returns the value of 'bestEffort'. For QOS parameter sets of downstream Service Flows, this attribute's value is reported as 'undefined'.

OBJECT-TYPE

This attribute specifies the nominal interval in microseconds between successive unicast request opportunities on an upstream Service Flow. This attribute applies only to upstream Service Flows with SchedulingType of value 'nonRealTimePollingService', 'realTimePollingService', and 'unsolictedGrantServiceWithAD'. The parameter is mandatory for 'realTimePollingService'. If the parameter is omitted with 'nonRealTimePollingService', the CMTS uses an implementation-dependent value. If the parameter is omitted with 'unsolictedGrantServiceWithAD(5)' the CMTS uses the value of the Nominal Grant Interval parameter. In all cases, the CMTS reports the value it is using when the parameter is applicable. The CM reports the signaled parameter value if it was signaled. Otherwise, it returns 0. If the referenced parameter is not applicable to the direction or scheduling type of the corresponding DOCSIS QOS Parameter Set, both CMTS and CM report this attribute's value as 0.

OBJECT-TYPE

This attribute specifies the maximum amount of time in microseconds that the unicast request interval may be delayed from the nominal periodic schedule on an upstream Service Flow. This parameter is applicable only to upstream Service Flows with a SchedulingType of 'realTimePollingService' or 'unsolictedGrantServiceWithAD'. If the referenced parameter is applicable but not present in the corresponding DOCSIS QOS Parameter Set, the CMTS uses an implementation-dependent value and reports the value it is using. The CM reports a value of 0 in this case. If the parameter is not applicable to the direction or upstream scheduling type of the Service Flow, both CMTS and CM report this attribute's value as 0.

OBJECT-TYPE

This attribute specifies the unsolicited grant size in bytes. The grant size includes the entire MAC frame data PDU from the Frame Control byte to the end of the MAC frame. The referenced parameter is applicable only for upstream flows with a SchedulingType of 'unsolicitedGrantServicewithAD' or 'unsolicitedGrantService', and it is mandatory when applicable. Both CMTS and CM report the signaled value of the parameter in this case. If the referenced parameter is not applicable to the direction or scheduling type of the corresponding DOCSIS QOS Parameter Set, both CMTS and CM report this attribute's value as 0.

OBJECT-TYPE

This attribute specifies the nominal interval in microseconds between successive data grant opportunities on an upstream Service Flow. The referenced parameter is applicable only for upstream flows with a SchedulingType of 'unsolicitedGrantServicewithAD' or 'unsolicitedGrantService(6)', and it is mandatory when applicable. Both CMTS and CM report the signaled value of the parameter in this case. If the referenced parameter is not applicable to the direction or scheduling type of the corresponding DOCSIS QOS Parameter Set, both CMTS and CM report this attribute's value as 0.

OBJECT-TYPE

This attribute specifies the maximum amount of time in microseconds that the transmission opportunities may be delayed from the nominal periodic schedule. The referenced parameter is applicable only for upstream flows with a SchedulingType of 'unsolicitedGrantServicewithAD' or 'unsolicitedGrantService(6)', and it is mandatory when applicable. Both CMTS and CM report the signaled value of the parameter in this case. If the referenced parameter is not applicable to the direction or scheduling type of the corresponding DOCSIS QOS Parameter Set, both CMTS and CM report this attribute's value as 0.

OBJECT-TYPE

This attribute specifies the number of data grants per Nominal Grant Interval (NomGrantInterval). The referenced parameter is applicable only for upstream flows with a SchedulingType of 'unsolicitedGrantServicewithAD' or 'unsolicitedGrantService', and it is mandatory when applicable. Both CMTS and CM report the signaled value of the parameter in this case. If the referenced parameter is not applicable to the direction or scheduling type of the corresponding DOCSIS QOS Parameter Set, both CMTS and CM report this attribute's value as 0.

OBJECT-TYPE

This attribute specifies the AND mask for the IP TOS byte for overwriting an IPv4 packet's TOS value or IPv6 packet's Traffic Class value. The IP packet TOS byte is bitwise ANDed with TosAndMask, then the result is bitwise ORed with TosORMask and the result is written to the IP packet TOS byte. A value of 'FF'H for TosAndMask and a value of '00'H for TosOrMask means that the IP Packet TOS byte is not overwritten. This combination is reported if the referenced parameter is not present in a QOS Parameter Set. The IP TOS octet as originally defined in RFC 791 has been superseded by the 6-bit Differentiated Services Field (DSField, RFC 3260) and the 2-bit Explicit Congestion Notification Field (ECN field, RFC 3168). The IPv6 Traffic Class octet RFC 2460 is consistent with that new definition. Network operators should avoid specifying values of TosAndMask and TosORMask that would result in the modification of the ECN bits. In particular, operators should not use values of TosAndMask that have either of the least-significant two bits set to 0. Similarly, operators should not use values of TosORMask that have either of the least-significant two bits set to 1. Even though this attribute is only enforced by the CMTS, the CM reports the value as signaled in the referenced parameter.

OBJECT-TYPE

This attribute specifies the OR mask for the IPv4 TOS value or IPv6 Traffic Class value. See the description of TosAndMask for further details. The IP TOS octet, as originally defined in RFC 791 has been superseded by the 6-bit Differentiated Services Field (DSField, RFC 3260) and the 2-bit Explicit Congestion Notification Field (ECN field, RFC 3168). The IPv6 Traffic Class octet RFC 2460 is consistent with that new definition. Network operators should avoid specifying values of TosAndMask and TosORMask that would result in the modification of the ECN bits.

OBJECT-TYPE

This attribute specifies the maximum latency between the reception of a packet by the CMTS on its NSI and the forwarding of the packet to the RF interface. A value of 0 signifies no maximum latency is enforced. This attribute only applies to downstream Service Flows. If the referenced parameter is not present in the corresponding downstream DOCSIS QOS Parameter Set, this attribute returns 0. This parameter is not applicable to upstream DOCSIS QOS Parameter Sets, so its value is reported as 0 in that case.

OBJECT-TYPE

This key represents the QoS Parameter Set Type of the Service Flow. The following values are defined: 'active' Indicates the Active QOS parameter set, describing the service currently being provided by the DOCSIS MAC domain to the service flow. 'admitted' Indicates the Admitted QOS Parameter Set, describing services reserved by the DOCSIS MAC domain for use by the service flow. 'provisioned' Indicates the QOS Parameter Set defined in the DOCSIS CM Configuration file for the service flow. Only the 'active ' service flow parameter set is required to be reported. The 'admitted ' and 'provisioned'sets are not required to be reported.

OBJECT-TYPE

This attribute specifies which transmit interval opportunities the CM omits for upstream transmission requests and packet transmissions. This object takes its default value for downstream Service Flows. Unless otherwise indicated, a bit value of 1 means that a CM must not use that opportunity for upstream transmission. The format of this string enumerated the bits from 0 to 31 from left to right, for example bit 0 corresponds to the left most bit of the fourth octet. (octets numbered from right to left). The bit positions are defined as follows: 'broadcastReqOpp' all CMs broadcast request opportunities 'priorityReqMulticastReq' priority request multicast request opportunities 'reqDataForReq' request/data opportunities for requests 'reqDataForData' request/data opportunities for data 'piggybackReqWithData' piggyback requests with data 'concatenateData' concatenate data 'fragmentData' fragment data 'suppressPayloadHeaders' suppress payload headers 'dropPktsExceedUGSize' A value of 1 means that the service flow must drop packets that do not fit in the Unsolicited Grant size. If the referenced parameter is not present in a QOS Parameter Set, the value of this object is reported as '00000000'H.

OBJECT-TYPE

This attribute indicates the set of QoS Parameter Set parameters actually signaled in the DOCSIS registration or dynamic service request message that created or modified the QoS Parameter Set. Possible QoS Parameter Set parameters are listed below with the corresponding TLV Type. A bit is set to 1 when the associated parameter is present in the original request as follows: 'trafficPriority' Traffic Priority (24/25.7) 'maxTrafficRate' Maximum Sustained Traffic Rate (24/25.8) 'maxTrafficBurst' Maximum Traffic Burst (24/25.9) 'minReservedRate' Minimum Reserved Traffic Rate (24/25.10) 'minReservedPkt' Assumed Minimum Reserved Rate Packet Size (24/25.11) 'activeTimeout' Timeout for Active QoS Parameters (24/25.12) 'admittedTimeout' Timeout for Admitted QoS Parameters (24/25.13) 'maxConcatBurst' Maximum Concatenated Burst (24.14) 'schedulingType' Service Flow Scheduling Type (24.15) 'requestPolicy' Request/Transmission Policy (24.16) 'nomPollInterval' Nominal Polling Interval (24.17) 'tolPollJitter' Tolerated Poll Jitter (24.18) 'unsolicitGrantSize' Unsolicited Grant Size (24.19) 'nomGrantInterval' Nominal Grant Interval (24.20) 'tolGrantJitter' Tolerated Grant Jitter (24.21) 'grantsPerInterval' Grants per Interval (24.22) 'tosOverwrite' IP Type of Service (DSCP) Overwrite (24.23) 'maxLatency' Maximum Downstream Latency (25.14) 'requiredAttrMask' Service Flow Required Attribute Mask (24/25.31) 'forbiddenAttrMask Service Flow Forbidden Attribute Mask (24/25.32) 'attrAggrMask' Service Flow Attribute Aggregation Mask (24/25.33) 'applicationId' Application Identifier (24/25.34) 'multipCntnReqWindow' Multiplier to Contention Request Backoff Window (24.25) 'multipBytesReq' Multiplier to Number of Bytes Requested (24.26) 'maxReqPerSidCluster' Maximum Requests per SID Cluster (47/89.3.1) 'maxOutstandingBytesPerSidCluster' Maximum Outstanding Bytes per SID Cluster (47/89.3.2) 'maxTotalBytesReqPerSidCluster' Maximum Total Bytes Requested per SID Cluster (47/89.3.3) 'maximumTimeInSidCluster' Maximum Time in the SID Cluster (47/89.3.4) 'peakTrafficRate' Peak Traffic Rate (24/25.27) 'dsResequencing' - Downstream Resequencing (25.17) 'minimumBuffer' Minimum Buffer (24/25.35.1) 'targetBuffer' Target Buffer (24/25.35.2) 'maximumBuffer' Maximum Buffer (24/25.35.3) 'aqmDisabled' SF AQM Disabled (24/25.40.1) 'classicAqmLatencyTarget' Classic AQM Latency Target (24/25.40.2) 'dataRateUnit' Data Rate Unit Setting (24/25/70/71.41) 'aqmAlgInUse' AQM Algorithm (24/25.40.3) 'guaranteedGrantInterval' Guaranteed Grant Interval (24.44) 'guaranteedGrantRate' Guaranteed Grant Rate (24.45) 'guaranteedGrantRequestInterval' Guaranteed Request Interval (24.46) 'immedAqmMaxThrshld' Immediate AQM Maximum Threshold (24/25.40.4) 'immedAqmRngExpRampFunc' Immediate AQM Range Exponent of Ramp Function (24/25.40.5) 'pgsActivityDetectionDisable' PGS Activity Detection Disable (24.49) Note that when Service Class names are expanded, the registration or dynamic response message may contain parameters expanded by the CMTS based on a stored service class. These expanded parameters are not indicated by a 1 bit in this attribute. Note that even though some QoS Parameter Set parameters may not be signaled in a message (so that the parameter's bit in this object is 0), the DOCSIS specification requires that default values be used. These default values are reported as the corresponding attribute.

OBJECT-TYPE

This attribute provides read-create access to the CCAP to configure Downstream Queue Latency Estimates Histogram bin edges, using a method that is an alternative to using TLV Type [24/25].40.6 Latency Histogram Encodings defined in MAC and Upper Layer Protocols Interface Specification section C.2.2.9.15.6 Latency Histogram Encodings. The attribute is formatted as a string array of unsigned 16-bit integers, each representing a histogram bin edge in units of 10 microseconds. The size of the array can range from 0 to 15. Size 0 means the LatencyHistBinEdges array is not present or empty. The default value for this attribute is an empty array. Configuring one or more nonzero Downstream Queue Latency Estimates Histogram bin edges causes the CCAP to calculate queue latency estimate histogram results for any downstream service flow using the Service Class parameters. If LatencyHistBinEdges is not present or empty for a ServiceClass instance, the instance has no effect on whether a Queue Latency Estimates Histogram is calculated for a service flow. If an operator would like the CCAP to calculate the Queue Latency Estimates Histogram for a service flow that uses a particular Service Class, the operator can create an instance of the ServiceClass object and configure the LatencyHistBinEdges attribute with n bin edge values. For any downstream service flow that is subsequently created and uses the Service Class defined by the instance, the CCAP is required to calculate a Queue Latency Estimate Histogram with n + 1 bins for the service flow.

OBJECT-TYPE

This object describes a provisioned ASF QoS Profile (AQP)for Aggregate Service Flows (ASF) on a CCAP. Each object instance defines a template for certain DOCSIS QoS Parameter Set values. When an Aggregate Service Flow is created, it may reference an AQP Name instead of providing explicit QoS Parameter Set values. In this case, the CCAP populates the QoS Parameter Set with the applicable corresponding values from the named AQP Name or Service Class Name. Subsequent changes to an AQP Name row do not affect the QoS Parameter Set values of any service flows already admitted. An AQP template applies to only a single direction, as indicated in the Direction attribute. An AsfQosProfile for ASF is an equivalent to a Service Class for a Service Flow.

OBJECT-TYPE

The conceptual row of the docsQosAqpTable.

OBJECT-TYPE

This attribute is the template for the Direction attribute of the AsfQosProfile.

OBJECT-TYPE

This attribute is the template for the relative priority of an Aggregate Service Flow/ QoS Parameter Set.

OBJECT-TYPE

This attribute is the template for the Maximum Aggregate Traffic Rate attribute (maximum sustained traffic rate allowed) for this ASF/Qos Parameter Set. This attribute represents the 4 byte value of the maximum aggregate traffic rate allowed for this ASF. All MAC frame data PDUs from the bytes following the MAC header HCS to the end of the CRC are included in calculating the maximum aggregate traffic rate. The number of bytes forwarded is limited during any time interval. The value 0 indicates no maximum traffic rate is enforced. The rate is specified in units of bps, kbps, mbps or gbps as specified by the DataRateUnitSetting attribute. This attribute applies to both upstream and downstream ASFs. This attribute also returns 0 if the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, or if the parameter is not applicable.

OBJECT-TYPE

This attribute is the template for the MaxTrafficBurst attribute of the Aggregate Service Flow/ QoS Parameter Set. If this value is not set, the default value is 3044, or 4000 if support for extended packet size is enabled.

OBJECT-TYPE

This attribute is the template for the Peak Traffic Rate allowed for this Aggregate Service Flow/QoS Parameter Set. This attribute represents the 4 byte value of the rate parameter 'P' of a token-bucket-based peak rate limiter for packets of this ASF. A value of 0 means the downstream peak traffic rate is not limited. The rate is specified in units of bps, kbps, mbps or gbps as specified by the DataRateUnitSetting attribute. This attribute also returns 0 if the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, or if the parameter is not applicable.

OBJECT-TYPE

This attribute is the template for the MinReservedRate attribute of the Aggregate Service Flow/ QoS Parameter Set. This attribute represents the 4 byte value of the guaranteed minimum rate allowed for this ASF. The value is calculated from the byte following the MAC header HCS to the end of the CRC. The value 0 indicates that no bandwidth is reserved. The rate is specified in units of bps, kbps, mbps or gbps as specified by the DataRateUnitSetting attribute. This attribute also returns 0 if the referenced parameter is not present in the corresponding DOCSIS QOS Parameter Set, or if the parameter is not applicable.

OBJECT-TYPE

This attribute is the template for the MinReservedPkt attribute of the Aggregate Service Flow/ QoS Parameter Set. The default value is CMTS vendor-dependent.

OBJECT-TYPE

This attribute indicates the base unit for the AsfQosProfile traffic rate configuration attributes Maximum Aggregate Traffic Rate (MaxAggregateTrafficRate), Minimum Reserved Traffic Rate (MinReservedRate), and Peak Traffic Rate (PeakTrafficeRate). The value of this attribute allows for their interpretation in units of Bps, Kbps, Mbps or Gbps. The default value for DataRateUnitSetting is bps.

OBJECT-TYPE

This attribute indicates if the Aggregate Service Flow is being used for Low Latency services. This implies the ASF is describing a Dual Queue SF setup underneath the ASF.

OBJECT-TYPE

This attribute represents the Service Class Name from which the parameter set values for the classic queue will be derived.

OBJECT-TYPE

This attribute represents the Service Class Name from which the parameter set values for the low latency queue will be derived.

OBJECT-TYPE

This attribute represents the coupling factor for the AQMs between the Classic Service Flow and the Low Latency Service Flow for this Aggregate Service Flow. The AqmCouplingFactor attribute is expressed in tenths, encoding an AQM Coupling Factor range from 0 - 25.5. If sub-TLV [70/71].42.5 AQM Coupling Factor is not provided to the CM and CCAP, the CM and CCAP are required use a default value of 2 for AQM Coupling Factor, so the default value of attribute AqmCouplingFactor is 20 .

OBJECT-TYPE

This attribute represents the latency threshold for the Queue Protection function in the Low Latency Service Flow.

OBJECT-TYPE

This attribute represents the Queuing Score Threshold for the Queue Protection function in the Low Latency Service Flow.

OBJECT-TYPE

This attribute represents the drain rate exponent for the Queue Protection function in the Low Latency Service Flow. The drain rate of the queuing score is expressed as an exponent of 2, in bytes/sec., e.g., a value of 19 means the Queue Protection function will use a value of : 2^19 bytes/sec.

OBJECT-TYPE

Packet classifiers assigned to the Low Latency service flow. Each classifier is encoded in hexBinary according to the TLV encoding. When multiple classifiers exist for the same Latency service flow, then they are encoded as the concatenated sequence of encodings for each classifier. See [MULPIv3.1] Quality-of-Service-Related Encodings (in Annex C). Because the TLV encoding for upstream classifiers is different than for downstream classifiers, the default value for this attribute depends on the value of the Direction attribute. This attribute is necessary to differentiate Low Latency Service Flow traffic from Classic Service Flow traffic. The minimum size of this attribute is a zero-length octet string, which could occur if the operator deletes the value. If this attribute is not populated, all traffic for this ASF would be mapped to the Classic Service Flow. No upper limit is defined for the length of this attribute.

For the CM, this table defines the latency histogram structure for each upstream histogram enabled service flow. The CM is required to create an active instance for every upstream service flow for which histogram calculation is enabled via the Latency Histogram Encodings TLV. Creating of an instance enables histogram calculation for the indexed service flow. Deleting an instance disables histogram calculation for the indexed service flow. The CM is required to delete an instance if the indexed service flow is deleted (e.g., because of a DSD operation) or the histogram calculation is disabled via the Latency Histogram Encodings TLV (i.e., because of a DSC operation). Prior to deactivating or deleting an instance in the SfLatencyHistCfg table, the CM is required, for the indexed service flow, to conclude any Latency Reporting Snapshot in progress, and delete the corresponding instance in the SfLatencyStats table. Once the SfLatencyHistCfg object is deactivated or deleted the CM does not collect any further latency statistics. The CM should not persist instances created in the SfLatencyHistCfg table across reinitializations. Bins are, by definition, consecutively numbered from one to sixteen. At most fifteen upper edges can be configured. Each configured upper edge is also the lower edge for the next bin (e.g., Bin 5 lower edge is defined by LatencyBin4UpperEdge). The lower edge of Bin 1 is defined as zero, and the upper edge of the final active bin (i.e., the bin corresponding to LatencyBinEdgeNum + 1) is defined as infinity. The CM validates the configured bin edges prior to activation. The Service Flow Latency Estimate values corresponding to Bin N are bounded as follows: Bin N lower edge is less than or equal to Service Flow Latency Estimate is less than Bin N upper edge. For the CCAP, this table defines the latency histogram structure for each downstream histogram enabled service flow. The CCAP is required to create an active instance for every downstream service flow for which histogram calculation is enabled via the Latency Histogram Encodings TLV. The activation of an instance enables histogram calculation for the indexed service flow. The deactivation or deletion of an instance disables histogram calculation for the indexed service flow. The CCAP is required to delete an instance if the indexed service flow is deleted (e.g., because of a DSD operation) or the histogram calculation is disabled via the Latency Histogram Encodings TLV (i.e., because of a DSC operation).

The CCAP validates the configured bin edges prior to activation. The Service Flow Latency Estimate values corresponding to Bin N are bounded as follows: Bin N lower edge is less than or equal to Service Flow Latency Estimate is less than Bin N upper edge.
