Ethernet Local Management Interface at a
Provider Edge
Provider Edge

The advent of Ethernet as a metropolitan-area network (MAN) and WAN technology imposes a new set
of operations, administration, and management (OAM) requirements on Ethernet's traditional
operations, which had been centered on enterprise networks only. The expansion of Ethernet technology
into the domain of service providers, where networks are substantially larger and more complex than
enterprise networks and the user-base is wider, makes operational management of link uptime crucial.
More importantly, the timeliness in isolating and responding to a failure becomes mandatory for normal
day-to-day operations, and OAM translates directly to the competitiveness of the service provider.
