Reliable Packet Transport Technologies for MPLS Networks
13 June 2004
Diverse applications in emerging data services demand flexibility of tradeoffs between resiliency and cost rather than a "one size fits all" approach. In this paper, we discuss Resilient Packet Mesh (RPM), a platform of packet transport technologies that provides a set of resiliency services for IP MPLS-based networks including two innovative resiliency services: packet 1+1 and real-time shared mesh. These resiliency services cover a whole spectrum of diverse user/application needs in resiliency and provide key tradeoffs in terms of recovery time, failure coverage, and required protection capacity.
