Relationship to other Standards Bodies 14

Part of International Standards Community Working outward from the core Working inward from the edge Making it work together The MEF’s role is largely additive to these organizations, developing necessary additional specifications that are required to enable Carrier Ethernet. The MEF also provides inputs in support of Carrier Ethernet to these bodies via its participating members and liaisons. It is not within the scope of the MEF to endorse or otherwise the work of other standards bodies and associations 15

What Do We Mean By “Ethernet?” Ethernet as a point-to-point link IEEE 802.3 view Ethernet as a packet switched network (PSN) infrastructure IEEE 802.1 (bridging) view ITU-T SG15 / SG13 managed Ethernet network view Ethernet as a service MEF view – user-to-user transfer of 802.3 frames over any transport layer E-Line, E-LAN and E-Tree 16

Complementary Standards Activities Goals Reach consensus, bring MEF work to other bodies, re-use work of other bodies, work with other bodies, avoid duplication, keep in communications Scalability ITU-T Provider Bridge IEEE 802.1ad Provider Backbone Bridge IEEE 802.1ah (MAC-in-MAC, and extended label space) ITU-T SG 15 has referenced the MEF service work in their documents that describe EPL and EVPL. IETF Layer 2 VPNs IEEE Service Management IEEE IEEE 802.1ag Fault Management IEEE 802.3ah link OAM ITU-T ITU-T SG13 for Service OAM Working with ITU SG 4 on harmonizing their work with MEF 7 and adding additional features of interest to the MEF such as support of E-LMI OIF Customer signaling of Ethernet Services Reliability IETF MPLS Fast Reroute, graceful restart 17

Global Expansion to Carrier Ethernet Relationship between the MEF Specifications and Carrier Ethernet – The technical work of the MEF as described in the specifications, together with the work of associated standards bodies, collectively enable the functionality and attributes of Carrier Ethernet – The completed specifications continue to refer to MENs (Metro Ethernet Networks) but this is now a generic term covering the enabled service network in the increasing variety of access, metro and long haul networks 19
