A carrier-oriented roundtable, one of the signature events at the MPLS & Ethernet World Congress. In this we focused on the feasibility of using MPLS end-to-end. It featured a star-cast of industry luminaries, who delved into the relative merits of Ethernet versus IP/MPLS for access/metro networks. We opened with the views of Thomas Beckhaus (DT) and Christoph Loibl (Silver Server) sharing...

thoughts and observations!
Continuing from the previous post, today we’ll share our observations on Day Two of the MPLS & Ethernet World Congress.
Day 2 of the Conference was focused on MPLS Transport Profile (MPLS-TP). This is a technological evolution of MPLS used to
enable it to better function and operate within traditional optical or transport networks. In particular, it is targeted at service providers
wishing to replace their traditional optical/transport networks with packet-optical ones. One of the key drivers for MPLS-TP was
Operations and Maintenance (OAM), allowing it to be more easily used by traditional telco operators that are accustomed to managing
and deploying optical networks (versus packet networks based on IP/MPLS). The most interesting presentation was given by George
Swallow entitled, “Dynamic MPLS-TP in a Unified MPLS Environment” who predicted (as he, I and others did at Cisco about 5 years
ago), that the new features from MPLS-TP will be eventually folded back into MPLS, effectively extinguishing MPLS-TP – and the
confusion around it being a new and separate technology. Day 2 also saw an interesting presentation by Yaakov Stein, CTO of RAD,
comparing Ethernet and MPLS-TP for the access, along several dimensions (such as maturity, scalability, security, and so on) on a
scale of 1-10 , where, per Yaakov’s assessment, Ethernet was a big winner for access deployments.
"MPLS End-to-End: A Realistic Paradigm?" Roundtable on Day 2 of the MPLS & Ethernet World Congress 2012 chaired by Dr.
Vishal Sharma (Metanoia, Inc.). The expert panelists included (from far left to right) Thomas Beckhaus (DT), Hector Avalos
(Ericsson), Xipeng Xiao (Huawei), George Swallow (Cisco), Yaakov Stein (RAD), Zeer Draer (MRV), Christoph Loibl (Silver
Server),and Rajesh Kumar Sundararajan (Aricent). (To enjoy the introductions and the operator's motivations for MPLS e2e, please

2. This was followed immediately by the roundtable/debate on “MPLS End-to-End: A Realistic Paradigm“, chaired by Vishal Sharma,
Metanoia, Inc. and included a varied set of eight panelists: from Deutche Telekom, and Silver Server (both operators), as well as
Ericsson, Huawei, Cisco (large vendors), RAD, MRV (access/metro and optical vendors), and Aricent (one of the largest integrators in
the industry).
The panel discussed some interesting options for why providers would consider MPLS end-to-end (having earlier defined what “end-
to-end” meant for the purposes of that discussion), with both Thomas Beckhaus of DT and Christoph Loibl of Silver Server sharing
the motivations that prompted their organizations to consider MPLS. There were opinions expressed that Ethernet and IP/MPLS
would likely co-exist for a while with Ethernet in the access/metro segments and IP/MPLS in the metro/core, although developments
in MPLS-TP and seamless MPLS, and the desire of operators to simplify operations by utilizing just one technology in all network
segments may skew preferences down the line. (More details about the panel, including video extracts of key points, will be
forthcoming in separate posts.)
So, what were your experiences at the MPLS & Ethernet World Congress this year? What stood out in your mind on Day Two? Which
issues jumped out at you? Do share them below, and share your knowledge and observations with the larger community!
