  1. Generalized MPLS (GMPLS) Support For Metro Ethernet Forum and G.8011 User-Network Interface (UNI)draft-berger-ccamp-gmpls-mef-uni-01.txtGeneralized MPLS (GMPLS) Support For Metro Ethernet Forum and G.8011 Ethernet Servicesdraft-berger-ccamp-gmpls-ether-svcs-00.txt Lou Berger <lberger@labn.net> Don Fedyk <dwfedyk@nortel.com> CCAMP - 70th IETF

  2. Recap • Objective of drafts: • Define GMPLS based support for MEF/G.8011 UNI • Based on GMPLS UNI (RFC4208) and GMPLS Calls (RFC4974) • Drafts provide: • New switching services • EPL: Ethernet Private Line • Supports a single port-to-port Ethernet connection (EVC) • EVPL: Ethernet Virtual Private Line • Multiplexed service – Based on Ethernet VLAN tags/IDs • Uses new label format • Other service and UNI specifics CCAMP - 70th IETF

  3. Document split: -gmpls-mef-uni-00.txt -gmpls-ether-svcs-00.txt covers new switching type and services Alignment with Ethernet Traffic parameters (draft-ietf-ccamp-ethernet-traffic-parameters-) General cleanup No significant technical changes -gmpls-mef-uni-01.txt covers UNI specifics Changes from previous version CCAMP - 70th IETF

  4. Technical Changes • Draft-berger-ccamp-gmpls-mef-uni-01.txt – None • Contains only UNI specifics • UNI Addressing (GMPLS UNI and CALLS) • Ethernet  IP address resolution • Connection Identification • Draft-berger-ccamp-gmpls-ether-svcs-00.txt (Deltas from draft-berger-ccamp-gmpls-mef-uni-00.txt) • Renamed encoding 8B/10Bline • New MEF-TRAFFIC TLV: L2 Control Protocol TLV • To align with [MEF-TRAFFIC] • Provides for handling of L2 control traffic at ingress and egress • Per MEF10.1, G.8011.1 and G.8011.2 • General text cleanup and references update CCAMP - 70th IETF

  5. L2 Control Protocol (L2CP) TLV • Carried in MEF Traffic Parameters (SENDER_TSPEC) • L2CP TLV Format: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Type=2 | Length=4 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | IL2CP | EL2CP | Reserved | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ • IL2CP – Ingress Layer 2 Control Processing Value Description Reference ----- ----------- --------- 0 Reserved 1 Discard/Block [MEF10.1], [8011.1] and [8011.2] 2 Peer/Process [MEF10.1], [8011.1] and [8011.2] 3 Pass to EVC/Pass [MEF10.1], [8011.1] and [8011.2] 4 Peer and Pass to EVC [MEF10.1] • EL2CP – Egress Layer 2 Control Processing Value Description Reference ----- ----------- --------- 0 Reserved 1 Based on IL2CP Value [MEF10.1] 2 Generate [8011.1] and [8011.2] 3 None [8011.1] and [8011.2] 4 Reserved CCAMP - 70th IETF

  6. Open Issue • Further draft split?Proposal from Dimitri: • Split service document to match current RFC documents: • Protocol generic vs. Technology specific • Extensions to RFC 3471/RFC 3473 (label format and data channel switching) • Extensions to RFC 4974 (call related) • Extensions to Ethernet Traffic Parameters (for L2CP TLV) • Continue to have UNI specific document • Extensions to RFC 4208 CCAMP - 70th IETF

  7. Next steps • Identify and resolve open issues • Solicit feedback from MEF/OIF • Do we need a liaison? • Other comments? CCAMP - 70th IETF
