Two Novel Tunnel-based Ring Protection Switching for MPLS-TP Multicast Services

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


This paper investigates and compares the schemes suggested by the ITU and the IETF for MPLS-TP ring protection, and proposes two MPLS-TP ring protections to ensure reliability of MPLS-TP multicast services. The introduced ring protection schemes are named, the SPME-based-Wrapping protection scheme and the SPME-based-ROM-Wrapping protection scheme, both of which aim at retaining the advantages of previous MPSL-TP ring protections and avoiding limitations. In the paper, the requirements of designing an efficient and reliable MPLS-TP ring protection, for instance with respect to label consumption, bandwidth utilization and operation complexity are well considered and also set concrete evaluating criteria for new proposed MPLS-TP ring protection schemes for multicast services.
