Ethernet in the First Mile (Paperback)

High Quality Content by WIKIPEDIA articles! Ethernet in the First Mile (EFM), also known as IEEE 802.3ah, is a collection of protocols specified in IEEE 802.3, defining the Ethernet in the access networks, i.e. first or last mile. With wide, metro and local area networks already standardized, the EFM allows continuous standard Ethernet network across the globe, eliminating non-native transport such as Ethernet over ATM from the access networks. EFM also addresses other issues, required for mass deployment of Ethernet services, such as operations, administration & management (OA&M) and compatibility with existing technologies (e.g. spectral compatibility for copper).
