As more and more traffic is being delivered in Ethernet format, carriers are realizing the advantages to converging on a pure Ethernet infrastructure, but are not able to do so with Ethernet as presently defined. New ITU-T Recommendations, such as Y.1731 for Ethernet OAM and G.8031 for Ethernet protection switching, provide features essential for operational maintenance of Ethernet networks. Recently proposed mechanisms for configuring point-to-point connections in Ethernet networks close another gap between Ethernet and SONET/SDH networks. The final difference between conventional TDM-based networks and Ethernet is that the former also transport frequency information, needed for some applications, while Ethernet does not.
