The Great Debate: TRILL Versus 802.1aq (SPB)

Moderator: Dani Roisman

Panelists: Donald Eastlake, TRILL; Peter Ashwood-Smith, Huawei Fellow; Paul Unbehagen, Alcatel-Lucent; Srikanth Keesara, Avaya
Presentation Date: October 4, 2010, 3:00 PM - 4:00 PM

Room: Ellington

Abstract:
Two competing methods of solving the multipath/redundant L2 Ethernet challenge have been emerging over the years, and have now become viable. In this showdown of TRILL versus 802.1aq (SPB) we will debate issues including stability, convergence, vendor support, and standardization.

Dani Roisman Biography:
Dani Roisman is currently the Sr. Director of network engineering and Operations at The Planet Internet Services, where he oversees the teams that build and run the network that supports over 45,000 managed servers across 7 datacenters. Prior to The Planet, he was a Senior Network Architect and Network Engineering Team Lead at Peak Web Consulting, and Director of Network Engineering and Facilities Architecture at Sony Online Entertainment.

Dani has specialized in large content datacenters and networks, with a focus on peering and multi-homing to reduce costs, improve customer negotiating stance, as well as increased network capacity, performance, and fault-tolerance. His network design and implementation accomplishments include massively-multiplayer games (EverQuest, Star Wars Galaxies, and PlanetSide) and social networking deployments hosting over 5,000 servers across 9 datacenters with Internet bandwidth capacities reaching 250Gbps.

Donald Eastlake Biography:
Donald Eastlake is co-chair of the IETF TRILL Working Group and a member of the IEEE 802.1 Working Group. Donald is author of about 50 IETF RFCs, including the only RFC with "sex" in its title. He was also the editor of the TRILL base protocol specification, and an author of a number of other TRILL related Internet Drafts. Previous, he was a Distinguished Member of Technical Staff at Motorola.

Peter Ashwood-Smith Biography:
Peter Ashwood-Smith (peter.ashwoodsmith@huawei.com) is a Huawei Fellow with B.S and M.S. degrees in computer science from the Universities of Victoria and Toronto. He has worked on the design, standardization, implementation, deployment, and support of many modern routing protocols (e.g., label switched networks including PORS, ATM, MPLS, and GMPLS). Peter previously worked at Nortel where he held a number of product related positions and a fellowship. He currently has approximately 32 networking related patents. His interests and research are now tending in the direction of computation-based/non-label-switched protocols and as a result Peter is now participating in the design, standardization, implementation and productization of IEEE 802.1aq/Shortest Path Bridging.

Paul Unbehagen Biography:
Paul Unbehagen is an active member of the IEEE and IETF.
He has also participated in several IETF WGs to include IS-IS, BGP, L2VPN, and IPVPNs and is currently the author of the IP/SPB IETF draft. He has several patents in communication protocols such as IS-IS and BGP.
Previously Paul has worked in numerous diverse networking environments to include the US Military, Bloomberg, MCI, and Nortel as well as a few startups. Paul thus has 14 years of deployment, operational, network design and architectural experience in live networks ranging from Enterprise to Carrier.

Srikanth Keesara Biography:
Srikanth Keesara is an Architect for the Modular Ethernet product portfolio at Avaya. He has worked for the past few years on SPB based product development and has been actively engaged in the deployment and support of this technology in large customer networks. Srikanth worked at Nortel within the Metro Ethernet Networks division and participated in the development of products based on IEEE-802.1ah, IEEE-802.1ag and SPB. He is a graduate of Indian Institute of Technology, Mumbai and Indian Insititute of Science Bangalore.
