Generalized Multiprotocol Label Switching (GMPLS) is the next-generation implementation of Multiprotocol Label Switching (MPLS). GMPLS extends the functionality of MPLS to include a wider range of label-switched path (LSP) options for a variety of network devices.
This document assumes you have a general understanding of MPLS, label switching concepts, and GMPLS Phase 1. For more information about MPLS, see the JUNOS MPLS Applications Configuration Guide . For more information about GMPLS Phase 1, see the JUNOS 5.5 Feature Guide at: http://www.juniper.net/techpubs/software/junos/junos55/feature-guide55/feature-guide-55.pdf .
