PANEL #1: Dynamic Layer 1/2 Circuits for High-Performance Applications
September 11, 2007
3:30 - 5:00 PM

Many emerging high performance applications require multi-gigabits network end-to-end, and/or deterministic connections with low loss, low latency, and minimal jitter. Traditional non-deterministic, “best effort” TCP/IP networks, do not perform well for large data transfers (terabytes or petabytes) due to the behavior of TCP over long distances. There are several research and development efforts across the globe underway to help develop the necessary technology to allow the capability in the network to dynamically set up Layer1/2 circuits and utilize the bandwidth only when necessary.

Panelist Questions:

  • Why are dynamic Layer1/2 circuits necessary for some of current and next generation’s applications?
  • What are the greatest challenges in designing a network with this capability: will the control plane play an essential role or the management plane or both?
  • What is the status of current research on this topic?
  • Are there any standardization efforts underway?
  • Do you think the industry will adopt this technology? When?
  • Do you know of any deployments of this technology both testbeds and carrier networks?

Panelists:

  • Vincent Chan, MIT
  • George Clapp, Telcordia
  • Jerry Sobieski, Mid-Atlantic Crossroads (MAX)
  • Tomohiro Kudoh, AIST, Japan

 

 

PANEL #2: Ethernet in Metro and WAN Networks vs. IP
September 12, 2007
3:30 - 5:00 PM

Ethernet has been proposed as a viable transport networking technology for the WAN and metro networks. The IEEE and ITU have already approved (Provider Bridges/802.ad, Ethernet OAM Mechanisms/Y.1731) and are currently reviewing (PBB/802.1ah, PBB-TE /802.1Qay, Ethernet Protection/G.8031 ) standards that allow for this new transport role of Ethernet. The Ethernet technology is widely accepted and ubiquitous and many vendors have already started to make and sell new products that will take it into the WAN. Carriers will soon make decisions on weather these new Ethernet features will provide the necessary CAPEX/OPEX to replace existing WAN technologies. This panel will debate next generation WAN technologies and the role of Ethernet.

Panelist Questions:

  • Is Ethernet is a viable technology for the WAN?
  • Will IP/MPLS and Ethernet’s PBB-TE will coexist in next generation networks or do you think one will prevail over the other?
  • What are the pros and cons of using Ethernet in the WAN?
  • What are the pros and cons of using IP directly over Optical?
  • What is the status of current research on this topic?
  • What do you think of the standardization efforts underway?
  • Do you think the industry will adopt Ethernet in the WAN? When?Do you know of any deployments of this technology both testbeds and carrier networks?

Panelists:

  • Wes Doonan, Adva
  • Dave Allan, Nortel
  • Anush Elangovan, Cisco
