…functionality for WAN Ethernet is currently under development in the ITU (Y.1731), the IEEE (802.1ag and 802.3) and MEF (MEF10/16). Connectivity OAM---as viewed by the service provider and network operator---is primarily supported by ITU-T Y.1731 and IEEE 802.1ag. The IEEE 802.3 Ethernet in the First Mile (EFM…

…layer and/or the circuit- like nature of connection-oriented Ethernet tunnels, with future support for 802.1ag Connectivity Fault Management and Y.1731 performance measurements to trigger a tunnel protection switch using G.8031 techniques.* Together, these capabilities provide real-time SONET/SDH-like…
