Abstract:

MPLS introduces a variety of connectivity options into packet networking that provides significant challenges to reliable network operation. The potential complexity of a toolkit that address the full spectrum of the MPLS architecture has to date been intimidating, and has limited the approach taken to simply chipping away at the problems.

This session will explore a number of the issues associated with OAM for different applications of MPLS. It outlines what can be achieved, provides a strong rationale for the separation of monitoring and diagnostic tools, and suggests that MPLS hierarchy may be the answer to apparently intractable OAM problems. Included is an overview of the various approaches considered by both the IETF and the ITU and how MPLS OAM can fit into an overall GMPLS/PW hierarchy.

David Allan is a senior advisor, MPLS Standards, Portfolio Integration and Architecture at Nortel Networks. He has been active in data telecommunications standards and R&D for the past seven years including WG chair roles in the DSL Forum and the IETF. He has been active as an architect, design engineer and developer in diverse areas of technology ranging from process control to financial transaction processing for almost twenty five years. His current role at Nortel Networks is focused on MPLS standards and the evolution of MPLS into a multi-service transport.
