Abstract :
Transport networks are currently evolving from traditional circuit switching technologies toward packet switching technologies. Multi Protocol Label Switching (MPLS) Transport Profile (MPLS-TP) is an emerging technology addressing the need for packet transport networks. Protection Switching in Packet Transport Rings is an important area of work in the context of MPLS-TP in order to support the packet transport reliability requirements given the widespread adoption of ring topologies in metro transport networks. This paper reviews the use cases for MPLS-TP ring protection switching, how one of the proposed mechanisms, namely MPLS-TP Ring Protection Switching (MRPS), can address these requirements and some possible enhancements to the MRPS base mechanism.
