Topic: “Beyond the Hype: A Practical Evaluation of MPLS, T-MPLS and PBB-TE for Carrier-Grade Packet Transport”
Speaker: Dr Raymond Xie, Senior Product Manager, Sycamore Networks

Abstract
Driven by exponential growth of IP/Ethernet traffic, end-to-end Ethernet WAN services are rapidly becoming a critical revenue source for carriers. Traditionally, carriers might have offered Ethernet interfaces through legacy SDH or ATM networks, but their limited throughput, scalability and efficiency have hindered service growth.

Ethernet services are increasingly transported over IP/MPLS in core networks, with improved flexibility and bandwidth efficiency. Alternatively, Transport-MPLS (T-MPLS) could provide a cost-effective packet transport network with OAM based on transport concepts. The emergence of Provider Backbone Bridging - Traffic Engineering (PBB-TE) technology provides yet another option, and has fueled a debate over which approach will emerge as the favorite.

Stepping back from the marketing hype, this presentation will take a practical look at the encapsulation, interoperability, efficiency and OAM capabilities of these technologies, provide insights into migration, management plane and control plane integration issues, and include a comparative summary designed to help operators choose the best technology for their next-gen packet transport infrastructure.
