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

Changes from previous version

• 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

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.t
  xt)
• 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

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

7
Next steps

• Identify and resolve open issues
• Solicit feedback from MEF/OIF
• Do we need a liaison?
• Other comments?
