The docsQosServiceFlowPkts is defined: docsQosServiceFlowPkts OBJECT-TYPE ... DESCRIPTION "The number of Packet Data PDUs classified to this service flow. This object does not count MAC-specific management messages. CMs not classifying downstream packets may report this object's value as 0. " The classification process is also applied to the part of MAC-specific management messages. Is the means of this clarification that docsQosPktClassPkts counter counts all classified packets, but docsQosServiceFlowPkts only classified data packets. What about unclassified data packets sent through Primary SF. All of them will not be counted by both counters. Is this correct? As the result of discussion about docsQosServiceFlowPHSUnknowns you need to review also its description. This counter also requires DS classification. There are two proposals (one of them is yours): 1. To write for it the same as for docsQosServiceFlowPkts: "CMs not classifying downstream packets may report this object's value as 0. " 2. The counter may be useful. It is proposed to count all unknown phs for primary DS SF: "CMs not classifying downstream packets may count all these packets together and report it for Primary downstream service flow." Regards.

Expires September 2001 [Page 3] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 1. Introduction This memo specifies a MIB module in a manner that is compliant to the SNMP SMIv2[5][6][7]. The set of objects is consistent with the SNMP framework and existing SNMP standards. This memo is a product of the IPCDN working group within the Internet Engineering Task Force. Comments are solicited and should be addressed to the working group's mailing list at ipcdn@ietf.org and/or the author. 1.1 Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2271 [1]. o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in RFC 1155 [2], RFC 1212 [3] and RFC 1215 [4]. The second version, called SMIv2, is described in RFC 1902 [5], RFC 1903 [6] and RFC 1904 [7]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2272 [11] and RFC 2274 [12]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in RFC 1157 [8]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [13]. o A set of fundamental applications described in RFC 2273 [14] and the view-based access control mechanism described in RFC 2275 [15]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate Expires September 2001 [Page 4] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB. 1.2 Glossary Active QPS Active Qos Parameter Set. The set of QOS parameters that describe the current level service provided to a Service Flow. Active SF Active Service Flow. An SF with a non-empty Active QPS. Admitted QPS Admitted Qos Parameter Set. The set of QOS parameters that describe a level of service which the Service Flow is not currently using, but which it is guaranteed to receive upon the SF's request to make the set Active. Admitted SF A Service Flow with a non-empty Admitted QPS. CATV Cable TV CM Cable Modem, a modem connecting a subscriber's LAN the CATF RF network. DOCSIS CMs operate as a MAC layer bridge between the home LAN and the RF network. CMTS Cable Modem Termination System, the "head-end" device providing connectivity between the RF network and the Internet. Downstream The direction from the head end towards the subscriber. DSA Dynamic Service Addition, a DOCSIS MAC management message requesting the dynamic creation of a new Service Flow. New SFs are created with a three- message exchange of a DSA-REQ, DSA-RSP, and DSA-ACK. DSC Dynamic Service Change, a DOCSIS MAC management message requesting a change to the attributes of a Service Flow. SFs are changed with a three-message exchange of a DSC-REQ, DSC-RSP, and DSC-ACK. Expires September 2001 [Page 5] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 DSD Dynamic Service Delete, a DOCSIS MAC management message requesting the deletion of a Service Flow. SFs are deleted with a two-message exchange of a DSD-REQ and DSD-ACK. Head-end The origination point in most cable systems of the subsriber video signals. It is generally also the location of the CMTS. PHS Payload Header Suppression, a feature of DOCSIS 1.1 in which header bytes that are common in a sequence of packets of a Service Flow are replaced by a one-byte PHSI Index (PHSI) when transmitting the packet on the RF network. Provisioned QPS A QOS Parameter Set describing an envelope of service within which a Service Flow is authorized to request admission. All existing service flows must have a non-empty Provisioned QPS, hence all SFs are considered to be "Provisioned". SCN Service Class Name -- a named set of QOS parameters. A Service Flow may or may not be associated with a single named Service Class. A Service Class has as an attribute a Qos Parameter Set that is used as the default set of values for all Service Flows belonging to the Service Class. SID Service ID. A 16-bit integer assigned by the CMTS for an Upstream Service Flow with a non-empty Active QOS Parameter Set. SF Service Flow. A unidirectional stream of packets between the CM and CMTS. SFs are characterized as upstream or downstream. The SF is the fundamental unit of service provided on a DOCSIS CATV network. SFID Service Flow ID. A 32-bit unsigned integer assigned by the CMTS to each Service Flows Upstream The direction from a subscriber CM to the head-end CMTS. Expires September 2001 [Page 6] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 2. Overview This MIB provides a set of objects required for the management of DOCSIS 1.1 compliant Cable Modems (CM) and Cable Modem Termination Systems (CMTS). The specification is derived from the DOCSIS 1.1 Radio Frequency Interface specification [16]. Please note that the referenced DOCSIS standard only requires Cable Modems to process IPv4 customer traffic. Design choices in this MIB reflect those requirements. Future versions of the DOCSIS standard are expected to require support for IPv6 as well. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [19]. 2.1 Textual Conventions The textual convention "IfDirection" is defined to indicate the direction of a packet classifer relative to an interface. It takes the values of either downstream(1) or upstream(2). The textual convention "BitRate" corresponds to the bits per second as defined for QOS Parameter Sets in DOCSIS1.1. This definition includes all bits of the Ethernet MAC frame as transmitted on the RF network, starting with the Destination Address and ending with the Ethernet FCS. It does NOT includes bits in the DOCSIS MAC header. 2.2 MIB Organization The structure of the MIB is summarized below: Expires September 2001 [Page 7] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 docsQosMIB docsQosMIBObjects docsQosPktClassTable docsQosPktClassEntry docsQosPktClassId docsQosPktClassDirection docsQosPktClassPriority docsQosPktClassIpTosLow docsQosPktClassIpTosHigh docsQosPktClassIpTosMask docsQosPktClassIpProtocol docsQosPktClassIpSourceAddr docsQosPktClassIpSourceMask docsQosPktClassIpDestAddr docsQosPktClassIpDestMask docsQosPktClassSourcePortStart docsQosPktClassSourcePortEnd docsQosPktClassDestPortStart docsQosPktClassDestPortEnd docsQosPktClassDestMacAddr docsQosPktClassDestMacMask docsQosPktClassSourceMacAddr docsQosPktClassEnetProtocolType docsQosPktClassEnetProtocol docsQosPktClassUserPriLow docsQosPktClassUserPriHigh docsQosPktClassVlanId docsQosPktClassState docsQosPktClassPkts docsQosPktClassBitMap docsQosParamSetTable docsQosParamSetEntry docsQosParamSetServiceClassName docsQosParamSetPriority docsQosParamSetMaxTrafficRate docsQosParamSetMaxTrafficBurst docsQosParamSetMinReservedRate docsQosParamSetMinReservedPkt docsQosParamSetActiveTimeout docsQosParamSetAdmittedTimeout docsQosParamSetMaxConcatBurst docsQosParamSetSchedulingType docsQosParamSetNomPollInterval docsQosParamSetTolPollJitter docsQosParamSetUnsolicitGrantSize docsQosParamSetNomGrantInterval docsQosParamSetTolGrantJitter docsQosParamSetGrantsPerInterval docsQosParamSetTosAndMask docsQosParamSetTosOrMask docsQosParamSetMaxLatency Expires September 2001 [Page 8] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 docsQosParamSetType docsQosParamSetRequestPolicyOct docsQosParamSetBitMap docsQosServiceFlowTable docsQosServiceFlowEntry docsQosServiceFlowId docsQosServiceFlowSID docsQosServiceFlowDirection docsQosServiceFlowPrimary docsQosServiceFlowStatsTable docsQosServiceFlowStatsEntry docsQosServiceFlowPkts docsQosServiceFlowOctets docsQosServiceFlowTimeCreated docsQosServiceFlowTimeActive docsQosServiceFlowPHSUnknowns docsQosServiceFlowPolicedDropPkts docsQosServiceFlowPolicedDelayPkts docsQosUpstreamStatsTable docsQosUpstreamStatsEntry docsQosSID docsQosUpstreamFragments docsQosUpstreamFragDiscards docsQosUpstreamConcatBursts docsQosDynamicServiceStatsTable docsQosDynamicServiceStatsEntry docsQosIfDirection docsQosDSAReqs docsQosDSARsps docsQosDSAAcks docsQosDSCReqs docsQosDSCRsps docsQosDSCAcks docsQosDSDReqs docsQosDSDRsps docsQosDynamicAdds docsQosDynamicAddFails docsQosDynamicChanges docsQosDynamicChangeFails docsQosDynamicDeletes docsQosDynamicDeleteFails docsQosDCCReqs docsQosDCCRsps docsQosDCCAcks docsQosDCCs docsQosDCCFails docsQosServiceFlowLogTable docsQosServiceFlowLogEntry docsQosServiceFlowLogIndex docsQosServiceFlowLogIfIndex docsQosServiceFlowLogSFID Expires September 2001 [Page 9] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 docsQosServiceFlowLogCmMac docsQosServiceFlowLogPkts docsQosServiceFlowLogOctets docsQosServiceFlowLogTimeDeleted docsQosServiceFlowLogTimeCreated docsQosServiceFlowLogTimeActive docsQosServiceFlowLogDirection docsQosServiceFlowLogPrimary docsQosServiceFlowLogServiceClassName docsQosServiceFlowLogPolicedDropPkts docsQosServiceFlowLogPolicedDelayPkts docsQosServiceFlowLogControl docsQosServiceClassTable docsQosServiceClassEntry docsQosServiceClassName docsQosServiceClassStatus docsQosServiceClassMaxTrafficRate docsQosServiceClassMaxTrafficBurst docsQosServiceClassMinReservedRate docsQosServiceClassMinReservedPkt docsQosServiceClassMaxConcatBurst docsQosServiceClassNomPollInterval docsQosServiceClassTolPollJitter docsQosServiceClassUnsolicitGrantSize docsQosServiceClassNomGrantInterval docsQosServiceClassTolGrantJitter docsQosServiceClassGrantsPerInterval docsQosServiceClassMaxLatency docsQosServiceClassActiveTimeout docsQosServiceClassAdmittedTimeout docsQosServiceClassSchedulingType docsQosServiceClassRequestPolicy docsQosServiceClassTosAndMask docsQosServiceClassTosOrMask docsQosServiceClassDirection docsQosServiceClassPolicyTable docsQosServiceClassPolicyEntry docsQosServiceClassPolicyIndex docsQosServiceClassPolicyName docsQosServiceClassPolicyRulePriority docsQosServiceClassPolicyStatus docsQosPHSTable docsQosPHSEntry docsQosPHSField docsQosPHSMask docsQosPHSSize docsQosPHSVerify docsQosPHSIndex docsQosCMtsMacToSrvFlowTable docsQosCmtsMacToSrvFlowEntry docsQosCmtsCmMac Expires September 2001 [Page 10] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 docsQosCmtsServiceFlowId docsQosCmtsIfIndex The MIB is organized as 11 tables. Most tables are implemented in both the CM and CMTS; the docsQosUpstreamStatsTable and docsQosServiceFlowLogTable are implemented on the CMTS only. 2.2.1 docsQosPktClassTable The docsQosPktClassTable reports the Service Flow Classifiers implemented by the managed device. The table is indexed by the tuple { ifIndex, docsQosServiceFlowId, docsQosPktClassId }. The ifIndex corresponds to an CATV MAC interface. Each CATV MAC interfaces has a set of Service Flows, identified with a docsQosServiceFlowId value that is unique for that interface. Each service flow may have a number of packet classifiers that map packets to the flow. The ClassiferId for the classifier is unique only within a particular service flow. The semantics of packet classification are provided in [16]. Briefly, the DOCSIS MAC interface calls for matching packets based on values within the 802.2 (LLC), 802.3, IP, and/or UDP/TCP headers. Packets which map more than one classifier are prioritized according to their docsQosPktClassPriority value. The docsQosServiceFlowId (an index object) indicates to which service flow the packet is classified. The docsQosPktClassTable is distinct from the docsDevIpFilterTable of [21] in that docsQosPktClassTable is intended only to reflect the state of the dynamically added Service Flow Classifiers. SF Classifiers may be created only via a CM configuration file or from the Dynamic Service Addition (DSA) messages. For this reason, docsQosPktClassTable is read-only. The docsDevIpFilterTable is intended for external administration of packet classifiers. See the section "Externally Administered Classification", below. 2.2.2 docsQosParamSetTable The docsQosParamSetTable reports the values of Qos Parameter Set as defined in Section C.2.2 of [16]. In general, a Service Flow is associated with three different Qos Parameter Sets (QPSs): an "active" QPS, an "admitted" QPS, and a "provisioned" or "authorized" QPS. The relationship of these three sets is represented below: Expires September 2001 [Page 11] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 +---------------------+ | Provisioned | | | | +---------------+ | | | Admitted | | | | | | | | +---------+ | | | | | Active | | | | | | | | | | | +---------+ | | | | | | | +---------------+ | | | +---------------------+ Figure 1: Qos Parameter Sets The Provisioned QPS describes the maximum service envelope for which the SF is authorized. The Admitted QPS is the set of services for which a service flow has requested admission to the DOCSIS RF network, but which is not yet active. The Admitted QPS is used during the two-phase process of IP Telephony service flow admission to admit the bandwidth for a bidirectional voice call when the far end is ringing. Since ringing may occur for up to four minutes, this permits the bandwidth to be reserved but not actually consumed during this interval. The Active QPS is the set of services actually being used by the Service Flow. The DOCSIS v1.1 specification [16] defines what it means for a QPS envelope to be "within" another. In general, an inner QPS is considered to be "within" an outer QPS when all QOS parameters represent demands of equal or fewer resources of the network. In addition to their use as attributes of a Service Flow, a QPS is also an attribute of a Service Class. A DOCSIS CM configuration file or DSA message may request the creation of a new SF and give only the Service Class Name. The CMTS "expands the macro" of a Service Class Name creation by populating the Provisioned, Admitted, and/or Active QPSs of the Service Flow with the QPS of the Service Class Name. All of the QPSs of a Service Flow must be expansions of the same Service Class, and in this case the SF is said to "belong" to the Service Class. Changing the contents of a Service Class' QPS does not affect the QPS of any Service Flow earlier expanded from that Service Class name. Only the CMTS implements docsQosServiceClassTable. See [16] section 8 for a full description and the theory of operation of Docsis 1.1 QOS operation. Expires September 2001 [Page 12] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 The docsQosParamSetTable sets are indexed by { ifIndex, docsQosServiceFlowId, docsQosParamSetType}. ifIndex indicates a particular "DOCSIS MAC Domain". docsQosServiceFlowId uniquely identifies a service flow on that MAC domain. The docsQosParamSetType indicates whether the row describes an active, admitted, or provisioned Qos Parameter Set. The docsQosParamSetTable is read-only, because it indicates the Qos Parameter Set contents as defined by DOCSIS signalling. The docsQosServiceClassTable is read-create to permit managers to define a template of Qos Parameters that can be referenced by DOCSIS modems when creating their Qos Parameter Sets. 2.2.2.1 Interoperation_with_DOCSIS_1.0 The DOCSIS 1.0 DOCS-IF-MIB [22] specifies a docsIfQosProfileTable to describe the set of Class Of Service (COS) parameters associated with a COS "profile". The docsIfCmServiceTable, which contains one entry per SID, references this table with a docsIfCmServiceQosProfile number. The DOCSIS 1.1 CM registration process allows a modem to register as operating either with DOCSIS 1.0 or DOCSIS 1.1 functionality. For ease of expression, we call a modem registering with DOCSIS 1.0 functionality a "DOCSIS 1.0 modem", regardless of the modem's capabilities. A CMTS or CM supporting both DOCSIS 1.0 and DOCSIS 1.1 implements both the tables of [22] and the tables of this MIB. The interoperation goal is that before modem registration, the DOCSIS 1.0 MIB [22] applies. After registration, either the DOCSIS 1.0 or DOCSIS 1.1 MIB applies, depending on the mode with which the modem registered. The specific interoperation rules are: 1. When a CM initially ranges, both the CM and CMTS implement a row in DOCS-IF-MIB docsIfQosProfileTable and docsIfCmServiceTable corresponding to the default upstream Service ID (SID) used for pre-registration upstream traffic. The docsIfQosProfileTable row may be either exclusively referenced by the docsIfCmServiceTable row for the CM or, as is likely, multiply-referenced by several docsIfCmServiceTable rows. 2. Both a CMTS and CM implementing this MIB MUST NOT implement docsQosParamSetTable or docsQosServiceFlowTable rows until after the CM registers with DOCSIS 1.1 modem operation. Expires September 2001 [Page 13] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 3. When a modem registers with the CMTS as a "DOCSIS 1.1" modem, any exclusively-referenced row in DOCS-IF-MIB docsQosProfileTable representing the modems upstream Qos profile for pre-registration traffic MUST be removed. Multiply-referenced rows may remain, of course. The docsQosIfCmServiceQosProfile object in the CM's row of docsIfCmServiceTable MUST be set to zero. The docsIfCmServiceTable row for the DOCSIS 1.1 modem continues to exist, and the various statistic objects in that row are incremented. 4. When a DOCSIS 1.1 modem registers, both the CMTS and CM represent all service flows described in the modem configuration file in docsQosParamSetTable and docsQosServiceFlowTable. 5. At the CMTS, the Docsis 1.0 MIB objects docsIfCmtsServiceInPackets and docsIfCmtsServiceInOctets for a SID assigned to a Docsis 1.1 modem count only the pre- registration packets/bytes of those modems. 2.2.3 docsQosServiceFlowTable The docsQosServiceFlowTable provides read-only information about all of the service flows known by the device. It is indexed by the combination of { ifIndex, dosQosServiceFlowId }, where ifIndex corresponds to a CATV MAC interface and docsQosServiceFlowId is the 32- bit integer assigned by the CMTS controlling the MAC domain. A CM typically has only a single CATV MAC interface, while a CMTS may have several. See [22] for a description of the ifIndex numbering for DOCSIS devices. The table indicates whether a given SF is in the upstream or downstream direction, and whether it is the "primary" SF in that direction. The primary SF carries traffic that is not otherwise classified to any other SF in that direction. 2.2.4 docsQosServiceFlowStatsTable The docsQosServiceFlowStatsTable provides statistics for all currently existing SFs known by the managed device. It provides basic packet and octet counters, as well as certain other SF-specific stats such as the time at which the flow was created and how many seconds it has been active. The table also provides objects which can be used to fine-tune Expires September 2001 [Page 14] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 admission control decisions, namely the number of packets dropped or delayed due to QOS policing decisions enforced by the managed device. 2.2.5 docsQosUpstreamStatsTable This table provides statistics that are measured only at the CMTS in the upstream direction. These include a count of the number of fragmentation headers received, fragments discarded, and the number of concatenation headers received. 2.2.6 docsQosDynamicServiceStatsTable This table provides read-only stats on the operation of the Dynamic Service state machines as specified in section 9.4 of [16]. It provides a set of 14 counters *in each direction* for a Docsis MAC layer interface. That is, each Docsis MAC layer interface has one row for downstream stats, and a second row for upstream stats. Eight of the counters are DSx packet type counts, one counter for each of the eight DSx packet types. For example, the docsQosDSAReqs object in the upstream row at the CMTS counts the number of DSA-REQ messages received by the CMTS from that interface. The docsQosDSAReqs object in the downstream row at the CMTS counts the number of DSA-REQ messages transmitted by the CMTS on that interface. The remaining six counters per (interface, direction) combination count the number of successful and unsuccessful *transactions* that were initiated on the interface and direction. For example, the upstream docsQosDynamicAdds on a CMTS is the number of successfully completed CM-initiated dynamic additions, because at the CMTS a CM- initiated DSA starts in the upstream direction. The downstream docsQosDynamicAdds at a CMTS is the number of successful CMTS- initiated DSA transactions. Dynamic service transactions can fail for a number of reasons, as listed in the state machines of section 9.4. Rather than include still more counters for each different failure reason, they are grouped into a single count, e.g docsQosDynamicAddFails. Again, this object exists in both directions, so that locally originated vs remotely originated transaction failures are counted separately. Further troubleshooting of transaction failures will require vendor- specific queries and operation. Expires September 2001 [Page 15] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 2.2.7 docsQosServiceFlowLogTable This table contains a log of the Service Flows no longer existing in the docsQosServiceFlowTable. It is intended to be periodically polled by traffic monitoring and billing agents. It is implemented only at the CMTS. It contains a chronlogical log of SF session statistics, including a total count of packets and octets transferred on the SF. It includes time stamps of the SF creation and deletion time, as well as its number of active seconds. The active second count is the count of seconds that the SF had a non-empty Active Qos Parameter Set, i.e. it was eligible to pass data. For unicast SFs, it includes the CM MAC address associated with the flow for billing reference purposes. The maximum number of log records kept by a CMTS, and the duration that a log record is maintained in the table is vendor-specific. An explicit control object is provided so that the monitoring application can explicitly delete records it has read. 2.2.8 docsQosServiceClassTable This table defines the Service Class Name and references a Qos Parameter Set for each Service Class defined in a CMTS. It is indexed by the Service Class Name string itself. The table is read- create on a CMTS, and is not implemented in a CM. Each entry of the docsQosServiceClassTable should define a template for flows in a given direction (upstream or downstream). Some parameters of the docsQosServiceClassTable are specific to a particular direction, and so their values are not-applicable when used as a template for flows in the other direction. 2.2.9 docsQosServiceClassPolicyTable The docsQosServiceClassPolicyTable can be referenced by the docsDevFilterPolicyTable of [21] in order to have a "policy" that classifies packets to a named Service Class. This is one mechanism by which "external" entities (like an SNMP manager) may control the classification of packet for QOS purposes. Entries are indexed by a small integer docsQosServiceClassPolicyIndex. They provide a Service Class Name and a Rule Priority. A policy referencing a row of this table intends the packet to be forwarded on a Service Flow "belonging" to the named Service Class. See the section "Externally Administered Classification", below. This table is implemented on both the CM and CMTS, and is read-create on both. Expires September 2001 [Page 16] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 2.2.10 docsQosPHSTable The Payload Header Suppression (PHS) feature of DOCSIS 1.1 permits packets to replace the unchanging bytes of the Ethernet, IP, and UDP headers with a one-byte index when transmitting on the cable network. This is especially useful for IP Telephony packets, where such suppression can result in almost twice the number of calls supported within the same upstream channel. Each entry of the table corresponds to a PHS Rule as described in section 8.4 of [16]. The rules are identified by their corresponding service flow ID and docsQosPktClassId. A PHS rule is associated with exactly one classifier. The table is therefore indexed by the tuple { ifINdex, docsQosServiceFlowId, docsQosPktClassId}. This table is read-only, and MUST be implemented on both the CM and CMTS when PHS is supported. 2.2.11 docsQosCmtsMacToSrvFlowTable The docsQosCmtsMacToSrvFlowTable provides describes the mapping of CM mac addresses to the Service Flow Ids that are uniquely identified with that CM. External applications may collect statistics on all packets flowing through a CM by determining the SFID of all of its flows, and then collecting the statistics of packets and bytes for each flow. Downstream multicast service flows are not indicated in the docsQosCmtsMacToSrvFlowTable because they are not associated with only one CM. 3. Externally Administered Classification Docsis 1.1 provides rich semantics for the classification of packets to service flows with it Service Flow Classifier table. Service Flow Classifiers may be created statically in the DOCSIS CM configuration file, or may be created dynamically with Dynamic Service Addition (DSA) and Dynamic Service Change (DSC) DOCSIS MAC messages. Several major issues arose with the concept of externally administered classification, i.e. should an external SNMP manager be permitted to create classification rows? One problem was the co- ordination of classifier IDs, since such an approach would require either separate classifier ID number spaces or objects to co-ordinate both internal and external classifier ID assignments. A more serious problem, however, was the requirement that external creation of SF Classifiers would require "knowledge" of the individual Service Flow Expires September 2001 [Page 17] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 ID for service flows by external applications. It was strongly felt by the committee that SFIDs should remain an internal Docsis object, and not be transmitted as part of protocol flows, e.g. for IP packet telephony signalling. Docsis 1.1 introduced the concept of named Service Classes for ease of administration within a domain of CMs and CMTSs. What was desired was to permit external classification of packets to a Service Class, not a particular Service Flow. The DOCSIS committee therefore decided to use the already-defined IP Packet Filter Table [21] for the external classification of packets for QOS purposes. The docsDevIpPacketFilterTable defines similar packet matching criteria as docsQosPktClassTable, but it matches a packet to an arbitrary "policy set" instead of a particular Service Flow. One of the policies in the policy set then selects the Service Class of the SF on which to forward the packet. The docsQosServiceClassPolicyTable of this MIB defines the Service Class Name to which a packet is classified. The interaction of external and internal packet classification is depicted below.

The packet is first checked for matches with rows of the docsDevIpFilterTable. If it matches, the matching row provides a docsDevFilterPolicyId integer. 2. The docsDevFilterPolicyId indexes into one (or more) rows of docsDevFilterPolicyTable. Each row provides an arbitrary RowPointer (docsDevFilterPolicyPtr), corresponding to a policy to be applied to the packet. 3. This MIB defines a docsQosServiceClassPolicyTable whose entries may be pointed to by docsDevFilterPolicyPtr in Expires September 2001 [Page 19] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 order to administratively classify packets to a named DOCSIS Service Class. The docsQosServiceClassPolicyEntry provides a Service Class Name (SCN) as docsQosServiceClassPolicyName and a classification rule priority as docsQosServiceClassPolicyRulePriority. These are submitted to the device's Docsis MAC Layer entity as a special form of the MAC_DATA.request primitive, as described in Section E.2.1 of [16]. 4. The MAC Layer selects an SFID ("Y") of an active Service Flow belonging to the named class, choosing an SF arbitrarily if there is more than one. 5. The packet is then classified according to the docsQosPktClassTable, which may classify the packet to a different SFID "X". Associated with the classifier is a docsQosPktClassPriority. 6. In the event of a conflict between the SCN-determined SFID and the classified SFID, the greater of docsQosPktClassPriority and docsQosServiceClassPolicyRulePriority determines which SFID is selected to forward the packet. A packet which does not match a docsQosServiceClassPolicyEntry is directly submitted to the Docsis MAC layer, where the docsQosPktClassTable selects the SID on which it is to be forwarded. By convention (in [16]), the "internal" docsQosPktClassPriority values should be in the range of 64-191, while the "external" priorities may be either in the range 192-255 to override the internal classification or the range 0-63 to be overriden by internal classification. This classification mechanism applies both upstream from the CM and downstream from the CMTS. Expires September 2001 [Page 20] INTERNET-DRAFT<draft-ietf-ipcdn-qos-mib-05.txt> March 2001 4.
