MEF 4 Metro Ethernet Network Architecture Framework Part 1: Generic Framework
Introduces the framework and terminology for the services (Eth) layer
This document provides the Metro Ethernet Forum (MEF) generic architectural framework for Metro Ethernet Networks (MEN). The generic architecture framework describes the high-level constructs used to model the various architectural components of a MEN’s Ethernet services, transport services and application services layer networks. The MEF architecture model is based on the principle of layer network decomposition, where each layer network is constructed from a particular set of networking technologies (e.g., Ethernet, SONET/SDH, MPLS, etc.). The model reuses the native Ethernet frame structure and the architectural constructs created to describe connection and connection-less oriented transport networks in ITU-T Recommendations G.805 and G.809.
