For contention REQ and REQ/DATA regions, theminislots for a transmission opportunity within the region areconsidered utilized if the CMTS received an upstream burst withinthe opportunity from any CM on the physical channel. For all otherregions, utilized minislots are those in which the CMTS grantedbandwidth to any unicast SID on the physical channel.For an upstream interface that has multiple logical upstreamchannels enabled, the utilization index is a weighted sum ofutilization indices for the logical channels. The weight foreach utilization index is the percentage of upstream minislotsallocated for the corresponding logical channel.Example:If 75% of bandwidth is allocated to the first logical channeland 25% to the second, and the utilization indices for each are60 and 40 respectively, the utilization index for the upstreamphysical channel is (60 * 0.75) + (40 * 0.25) = 55. This figureapplies to the most recent utilization interval.Downstream Channel Utilization Index:The downstream channel utilization index is a percentage expressingthe ratio between bytes used to transmit data versus the total numberof bytes transmitted in the raw bandwidth of the MPEG channel. Aswith the upstream utilization index, the calculated value representsthe most recent utilization interval.Formula:Downstream utilization index =(100 * (data bytes / raw bytes)) =(100 * ((raw bytes - stuffed bytes) / raw bytes))Definitions:Data bytes: Number of bytes transmitted as data docsIfCmtsDownChannelCounterTable not-accessible current This table is implemented at the CMTS to collect downstreamchannel statistics for utilization calculations. docsIfCmtsDownChannelCounterEntry not-accessible current An entry provides a list of traffic counters for a singledownstream channel.An entry in this table exists for each ifEntry with anifType of docsCableDownstream(128). docsIfCmtsDownChnlCtrId read-only current The Cable Modem Termination System (CMTS) identificationof the downstream channel within this particular MACinterface.

These may merge, or be separated into paralleldata paths. diffServDataPathEntry not-accessible current An entry in the data path table indicates the start of a singleDifferentiated Services Functional Data Path in this device.These are associated with individual interfaces, logical orphysical, and therefore are instantiated by ifIndex. Therefore,the interface index must have been assigned, according to theprocedures applicable to that, before it can be meaningfullyused. Generally, this means that the interface must exist.When diffServDataPathStorage is of type nonVolatile, however,this may reflect the configuration for an interface whose ifIndexhas been assigned but for which the supporting implementation isnot currently present. diffServDataPathIfDirection not-accessible current IfDirection specifies whether the reception or transmission pathfor this interface is in view. diffServDataPathStart read-create current This selects the first Differentiated Services Functional DataPath Element to handle traffic for this data path. ThisRowPointer should point to an instance of one of:diffServClfrEntrydiffServMeterEntrydiffServActionEntrydiffServAlgDropEntrydiffServQEntryA value of zeroDotZero in this attribute indicates that noDifferentiated Services treatment is performed on traffic of thisdata path. A pointer with the value zeroDotZero normallyterminates a functional data path.Setting this to point to a target that does not exist results inan inconsistentValue error. If the row pointed to is removed orbecomes inactive by other means, the treatment is as if thisattribute contains a value of zeroDotZero. diffServDataPathStorage read-create current The storage type for this conceptual row. Conceptual rowshaving the value 'permanent' need not allow write-access to anycolumnar objects in the row. diffServDataPathStatus read-create current The status of this conceptual row.

Per the semantics of the classifier elementtable, these entries constitute one or more unordered sets oftests which may be simultaneously applied to a message toclassify it.The primary function of this table is to ensure that the value ofdiffServClfrId is unique before attempting to use it in creatinga diffServClfrElementEntry. Therefore, the diffServClfrEntry mustbe created on the same SET as the diffServClfrElementEntry, orbefore the diffServClfrElementEntry is created. diffServClfrEntry not-accessible current An entry in the classifier table describes a single classifier.All classifier elements belonging to the same classifier use theclassifier's diffServClfrId as part of their index. diffServClfrId not-accessible current An index that enumerates the classifier entries.

Setting this variable to'destroy' when the MIB contains one or more RowPointers pointingto it results in destruction being delayed until the row is nolonger used. diffServClfrElementNextFree read-only current This object contains an unused value for diffServClfrElementId,or a zero to indicate that none exist. diffServClfrElementTable not-accessible current The classifier element table enumerates the relationship betweenclassification patterns and subsequent downstream DifferentiatedServices Functional Data Path elements.diffServClfrElementSpecific points to a filter that specifies theclassification parameters. A classifier may use filter tables ofdifferent types together.One example of a filter table defined in this MIB isdiffServMultiFieldClfrTable, for IP Multi-Field Classifiers(MFCs). Such an entry might identify anything from a singlemicro-flow (an identifiable sub-session packet stream directedfrom one sending transport to the receiving transport ortransports), or aggregates of those such as the traffic from ahost, traffic for an application, or traffic between two hostsusing an application and a given DSCP. The standard BehaviorAggregate used in the Differentiated Services Architecture isencoded as a degenerate case of such an aggregate - the trafficusing a particular DSCP value.Filter tables for other filter types may be defined elsewhere. diffServClfrElementEntry not-accessible current An entry in the classifier element table describes a singleelement of the classifier. diffServClfrElementId not-accessible current An index that enumerates the Classifier Element entries.Managers obtain new values for row creation in this table byreading diffServClfrElementNextFree. diffServClfrElementPrecedence read-create current The relative order in which classifier elements are applied:higher numbers represent classifier element with higherprecedence. Classifier elements with the same order must beunambiguous i.e. they must define non-overlapping patterns, andare considered to be applied simultaneously to the trafficstream. Classifier elements with different order may overlap intheir filters: the classifier element with the highest orderthat matches is taken.On a given interface, there must be a complete classifier inplace at all times in the ingress direction. This means one ormore filters must match any possible pattern. There is no suchrequirement in the egress direction. diffServClfrElementNext read-create current This attribute provides one branch of the fan-out functionalityof a classifier described in the Informal Differentiated ServicesModel section 4.1.This selects the next Differentiated Services Functional DataPath Element to handle traffic for this data path. ThisRowPointer should point to an instance of one of:diffServClfrEntrydiffServMeterEntrydiffServActionEntrydiffServAlgDropEntrydiffServQEntryA value of zeroDotZero in this attribute indicates no furtherDifferentiated Services treatment is performed on traffic of thisdata path. The use of zeroDotZero is the normal usage for thelast functional data path element of the current data path.Setting this to point to a target that does not exist results inan inconsistentValue error. If the row pointed to is removed orbecomes inactive by other means, the treatment is as if thisattribute contains a value of zeroDotZero. diffServClfrElementSpecific read-create current A pointer to a valid entry in another table, filter table, thatdescribes the applicable classification parameters, e.g. an entryin diffServMultiFieldClfrTable.The value zeroDotZero is interpreted to match anything notmatched by another classifier element - only one such entry mayexist for each classifier.Setting this to point to a target that does not exist results inan inconsistentValue error. If the row pointed to is removed orbecomes inactive by other means, the element is ignored. diffServClfrElementStorage read-create current The storage type for this conceptual row. Conceptual rowshaving the value 'permanent' need not allow write-access to anycolumnar objects in the row. diffServClfrElementStatus read-create current The status of this conceptual row.

Therefore, this object is limited to IPv4and IPv6 addresses. diffServMultiFieldClfrDstAddr read-create current The IP address to match against the packet's destination IPaddress. This may not be a DNS name, but may be an IPv4 or IPv6prefix. diffServMultiFieldClfrDstPrefixLength indicates thenumber of bits that are relevant. diffServMultiFieldClfrDstPrefixLength read-create current The length of the CIDR Prefix carried indiffServMultiFieldClfrDstAddr. In IPv4 addresses, a length of 0indicates a match of any address; a length of 32 indicates amatch of a single host address, and a length between 0 and 32indicates the use of a CIDR Prefix. IPv6 is similar, except thatprefix lengths range from 0..128. diffServMultiFieldClfrSrcAddr read-create current The IP address to match against the packet's source IP address.This may not be a DNS name, but may be an IPv4 or IPv6 prefix.diffServMultiFieldClfrSrcPrefixLength indicates the number ofbits that are relevant. diffServMultiFieldClfrSrcPrefixLength read-create current The length of the CIDR Prefix carried indiffServMultiFieldClfrSrcAddr. In IPv4 addresses, a length of 0indicates a match of any address; a length of 32 indicates amatch of a single host address, and a length between 0 and 32indicates the use of a CIDR Prefix. IPv6 is similar, except thatprefix lengths range from 0..128. diffServMultiFieldClfrDscp read-create current The value that the DSCP in the packet must have to match thisentry. A value of -1 indicates that a specific DSCP value has notbeen defined and thus all DSCP values are considered a match. diffServMultiFieldClfrFlowId read-create current The flow identifier in an IPv6 header. diffServMultiFieldClfrProtocol read-create current The IP protocol to match against the IPv4 protocol number or theIPv6 Next- Header number in the packet.

Managers obtain newvalues for row creation in this table by readingdiffServMeterNextFree. diffServMeterSucceedNext read-create current If the traffic does conform, this selects the nextDifferentiated Services Functional Data Path element to handletraffic for this data path. This RowPointer should point to aninstance of one of:diffServClfrEntrydiffServMeterEntrydiffServActionEntrydiffServAlgDropEntrydiffServQEntryA value of zeroDotZero in this attribute indicates that nofurther Differentiated Services treatment is performed on trafficof this data path. The use of zeroDotZero is the normal usage forthe last functional data path element of the current data path.Setting this to point to a target that does not exist results inan inconsistentValue error. If the row pointed to is removed orbecomes inactive by other means, the treatment is as if thisattribute contains a value of zeroDotZero. diffServMeterFailNext read-create current If the traffic does not conform, this selects the nextDifferentiated Services Functional Data Path element to handletraffic for this data path.

If the row pointed to is removed orbecomes inactive by other means, the treatment is as if thisattribute contains a value of zeroDotZero. diffServMeterSpecific read-create current This indicates the behavior of the meter by pointing to an entrycontaining detailed parameters. Note that entries in thatspecific table must be managed explicitly.For example, diffServMeterSpecific may point to an entry indiffServTBParamTable, which contains an instance of a single setof Token Bucket parameters.Setting this to point to a target that does not exist results inan inconsistentValue error. If the row pointed to is removed orbecomes inactive by other means, the meter always succeeds. diffServMeterStorage read-create current The storage type for this conceptual row. Conceptual rowshaving the value 'permanent' need not allow write-access to anycolumnar objects in the row. diffServMeterStatus read-create current The status of this conceptual row.

Setting this variable to'destroy' when the MIB contains one or more RowPointers pointingto it results in destruction being delayed until the row is nolonger used. diffServAlgDropNextFree read-only current This object contains an unused value for diffServAlgDropId, or azero to indicate that none exist. diffServAlgDropTable not-accessible current The algorithmic drop table contains entries describing anelement that drops packets according to some algorithm. diffServAlgDropEntry not-accessible current An entry describes a process that drops packets according tosome algorithm. Further details of the algorithm type are to befound in diffServAlgDropType and with more detail parameter entrypointed to by diffServAlgDropSpecific when necessary. diffServAlgDropId not-accessible current An index that enumerates the Algorithmic Dropper entries.Managers obtain new values for row creation in this table byreading diffServAlgDropNextFree. diffServAlgDropType read-create current The type of algorithm used by this dropper. The value other(1)requires further specification in some other MIB module.In the tailDrop(2) algorithm, diffServAlgDropQThresholdrepresents the maximum depth of the queue, pointed to bydiffServAlgDropQMeasure, beyond which all newly arriving packetswill be dropped.In the headDrop(3) algorithm, if a packet arrives when thecurrent depth of the queue, pointed to bydiffServAlgDropQMeasure, is at diffServAlgDropQThreshold, packetscurrently at the head of the queue are dropped to make room forthe new packet to be enqueued at the tail of the queue.In the randomDrop(4) algorithm, on packet arrival, an ActiveQueue Management algorithm is executed which may randomly drop apacket. This algorithm may be proprietary, and it may drop eitherthe arriving packet or another packet in the queue.diffServAlgDropSpecific points to a diffServRandomDropEntry thatdescribes the algorithm. For this algorithm,diffServAlgDropQThreshold is understood to be the absolutemaximum size of the queue and additional parameters are describedin diffServRandomDropTable.The alwaysDrop(5) algorithm is as its name specifies; alwaysdrop. In this case, the other configuration values in this Entryare not meaningful; There is no useful 'next' processing step,there is no queue, and parameters describing the queue are notuseful. Therefore, diffServAlgDropNext, diffServAlgDropMeasure,and diffServAlgDropSpecific are all zeroDotZero. diffServAlgDropNext read-create current This selects the next Differentiated Services Functional DataPath Element to handle traffic for this data path. ThisRowPointer should point to an instance of one of:diffServClfrEntrydiffServMeterEntrydiffServActionEntrydiffServQEntryA value of zeroDotZero in this attribute indicates no furtherDifferentiated Services treatment is performed on traffic of thisdata path. The use of zeroDotZero is the normal usage for thelast functional data path element of the current data path.When diffServAlgDropType is alwaysDrop(5), this object isignored.Setting this to point to a target that does not exist results inan inconsistentValue error. If the row pointed to is removed orbecomes inactive by other means, the treatment is as if thisattribute contains a value of zeroDotZero. diffServAlgDropQMeasure read-create current Points to an entry in the diffServQTable to indicate the queuethat a drop algorithm is to monitor when deciding whether to dropa packet.

Other algorithms will needto define their own semantics for this threshold. diffServAlgDropSpecific read-create current Points to a table entry that provides further detail regarding adrop algorithm.Entries with diffServAlgDropType equal to other(1) may have thispoint to a table defined in another MIB module.Entries with diffServAlgDropType equal to randomDrop(4) must havethis point to an entry in diffServRandomDropTable.For all other algorithms specified in this MIB, this should takethe value zeroDotZero.The diffServAlgDropType is authoritative for the type of the dropalgorithm and the specific parameters for the drop algorithmneeds to be evaluated based on the diffServAlgDropType.Setting this to point to a target that does not exist results inan inconsistentValue error. If the row pointed to is removed orbecomes inactive by other means, the treatment is as if thisattribute contains a value of zeroDotZero. diffServAlgDropOctets read-only current The number of octets that have been deterministically dropped bythis drop process.Discontinuities in the value of this counter can occur at re-initialization of the management system and at other times asindicated by the value of ifCounterDiscontinuityTime on therelevant interface. diffServAlgDropPkts read-only current The number of packets that have been deterministically droppedby this drop process.Discontinuities in the value of this counter can occur at re-initialization of the management system and at other times asindicated by the value of ifCounterDiscontinuityTime on therelevant interface. diffServAlgRandomDropOctets read-only current The number of octets that have been randomly dropped by thisdrop process.

Note that this differs from the physical queue limit,which is stored in diffServAlgDropQThreshold. Changes in thisvariable may or may not be reflected in the reported value ofdiffServRandomDropMaxThreshBytes. diffServRandomDropProbMax read-create current The worst case random drop probability, expressed in drops perthousand packets.For example, if in the worst case every arriving packet may bedropped (100%) for a period, this has the value 1000.Alternatively, if in the worst case only one percent (1%) oftraffic may be dropped, it has the value 10. diffServRandomDropWeight read-create current The weighting of past history in affecting the ExponentiallyWeighted Moving Average function that calculates the currentaverage queue depth. The equation usesdiffServRandomDropWeight/65536 as the coefficient for the newsample in the equation, and (65536 -diffServRandomDropWeight)/65536 as the coefficient of the oldvalue.Implementations may limit the values of diffServRandomDropWeightto a subset of the possible range of values, such as powers oftwo. Doing this would facilitate implementation of theExponentially Weighted Moving Average using shift instructions orregisters. diffServRandomDropSamplingRate read-create current The number of times per second the queue is sampled for queueaverage calculation. A value of zero is used to mean that thequeue is sampled approximately each time a packet is enqueued (ordequeued). diffServRandomDropStorage read-create current The storage type for this conceptual row.
