Abstract

A system and method are disclosed for reliable communications in a packet network. A system that incorporates teachings of the present disclosure may include, for example, a network management system (NMS) having a controller programmed to establish between first and second customer edge (CE) routers in a full mesh packet network first and second logical data tunnels conforming to an isolation protocol, synchronize packet data in the first and second logical data tunnels, enable packet data exchanges between the first and second CE routers over the first logical data tunnel, direct the first and second CE routers to duplicate the packet data exchanged between them over the second logical data tunnel, and direct the first and second CE routers to synchronously switch to the second logical data tunnel upon detecting a fault in the first logical data tunnel.
