METHOD AND SYSTEM FOR PROVIDING USER ACCESS TO COMMUNICATION SERVICES, AND RELATED COMPUTER PROGRAM PRODUCT

摘要

system for providing to users (CPE) of data communication services access to a communication network providing these services includes an edge node (Mw) of the communication network providing these services as well as a packet network (N) such as an Ethernet connecting the users (U) to the edge node (Mw). The packet network (N) is equipped with operation and maintenance (OAM) procedures for preserving edge connectivity over the packet network (Nn). The edge node (BRAS; Mw) has associated a backup edge node (BRAS; Mp) providing access to the communication network. Preferably, the backup edge node (BRAS; Mp) is reachable by the users (U) via the packet network (N) by using an address common to the edge node (BRAS; Mw) and the backup edge node (BRAS; Mp) associated therewith. In the presence of failure of the edge node (BRAS; Mw), connection is established between the users (U) and the backup edge node (BRAS; Mp) by applying the operation and maintenance (OAM) procedures. Preferably, this, occurs by using the address common to the edge node (BRAS; Mw) and the associated backup edge node (BRAS; Mp).
