"This document defines three Service constructs called Ethernet Service Types and six Ethernet Services with Service Attributes and parameters as specified in MEF 10.3, “Ethernet Services Attributes” and in MEF 45, “Multi-CEN Layer 2 Control Protocol”. These Service Types are used to create Point-to-Point, Multipoint-to-Multipoint, and Rooted-Multipoint Ethernet Services that are either Port or VLAN based. This document supersedes and replaces MEF 6.1, Ethernet Services Definitions – Phase 2.
In addition, an informative appendix is provided showing examples of some of the defined Services. This document also provides guidance on backwards compatibility to a Service as defined in MEF 6.1, Ethernet Services Definitions – Phase 2."
