scope:

This Recommendation describes the functional architecture of Ethernet networks using the modelling methodology described in [ITU-T G.805], [ITU-T G.809] and [ITU-T G.800]. The Ethernet network functionality is described from a network level viewpoint, taking into account an Ethernet network layered structure, client characteristic information, client/server layer associations, networking topology, and layer network functionality providing Ethernet signal transmission, multiplexing, routing, supervision, performance assessment, and network survivability. The functional architecture of the server layer networks used by the Ethernet network is not within the scope of this Recommendation. Such architectures are described in other ITU-T Recommendations or IETF RFCs.

The bases for this Recommendation are the Ethernet specifications in [IEEE 802.1Q] and [IEEE 802.3].
