(Message sent via IEEE Standards webmail) ----------------------------------------- Commenter = Glen Kramer Affiliation = Broadcom SenderEmail = gkramer@broadcom.com SenderPhone = (707)529-0917 StandardRev = IEEE Std 1904.1-2013 SubclauseNumber = 7.4.5 Page = 138 Rationale = There are several problems with Package A multicast (see rmtf_1510_knittle_1.pdf): 1) Different mcast groups may need to be identified by different fields. But the aRuleIpmcFwrConfig (0xD7/0x05-05) attribute has one value for the entire ONU. 2) The aRuleIpmcFwrConfig (0xD7/0x05-05) attribute refers to fields IP-DA and IP-SA. No such fields are defined anywhere. The fields should be IPv4_DA, IPv6_DA, IPv4_SA, and IPv6_SA. It is unclear whether the ONU should create rules to match IPv4, IPv6, or both. 3) Missing configuration messages for non-IP multicast 4) Different UNIs have different numbers and sizes of egress queues, but the eOAM_MC_Control eOAMPDU does not specify which queue should be used at each UNI. 5) eOAM_MC_Control eOAMPDU is different from its counterpart in DPoE 6) Unclear ONU behavior If Multicast Registration message is received, but IP Multicast Config message is not: should frames with given mLLID be dropped or processed using unicast rules? Also, multicast specifications in DPoE 2.0 and in SIEPON-A have diverged. This MR attempts to fix the technical issues and restore the alignment between DPoE 2.0 and in SIEPON- A. ProposedChange = The outline of the proposed solution is shown in rmtf_1510_kramer_multicast_outline_1.pdf The detailed proposed changes are shown in these files: 1) Operation description in Clause 7.4.5: rmtf_1510_kramer_multicast_operation_1.pdf 2) Classifier support for "LLID value" - rmtf_1510_kramer_multicast_llid_value_1.pdf 3) New attributes and actions: rmtf_1510_kramer_multicast_new_attr_1.pdf Impact = None. Existing multicast specification is unimplementable and multicast based on mLLID has not been deployed yet. ----------------------------------------- (End of IEEE Standards webmail message)
