Abstract
A system for providing, to users of data communication services, access to a communication network providing these services includes an edge node as well as a packet network, such as an Ethernet connecting the users to the edge node. The packet network is equipped with operation and maintenance procedures for preserving edge connectivity over the packet network. The edge node is associated with a backup edge node, which also provides access to the communication network. Preferably, the backup edge node has the same address as the edge node such that, in the presence of failure of the edge node, seamless connection is established between the users and the backup edge node by applying the operation and maintenance procedures.
