Resilient multipoint networks based on redundant trees

Abstract

Connection-oriented packet forwarding technologies such as multiprotocol label switching (MPLS), generalized MPLS (GMPLS), and new entrant MPLS transport profile (MPLS-TP) are all evolving to meet the increasing demand for an efficient support of multicast applications like Internet Protocol television (IPTV) and multicast virtual private networks (VPNs
