About the talk:
 

We are at an inflection point in the architecture of core networks. On one hand, new applications based on video and other high bandwidth content are becoming ubiquitous and already dominate the bandwidth. On the other hand, service providers are continuing to increase the consumer access bit rate into the network at a fast pace. This is pushing the demands on the core while reducing the revenue per bit, forcing SPs to rethink the architecture. The base technologies for this transition are already in place: IP has established itself as a technology of choice for consumer and business services, while DWDM technology is now the established transport technology for high speed connections. Given this, we are attempting to re-architect the core by combining IP and DWDM more efficiently, while taking into account practical technical and organizational limitations that may hinder the deployment of such a new architecture. In this talk I will discuss the resulting solution - IPoDWDM - its possible evolution, the limitations we have enountered and how we are addressing them.

 

About the speaker:
 

Ori Gerstel (SM'01) is a senior technical leader in the Core Routing Unit at Cisco. His main role is to define the architecture of IP and Optical networks integration (IPoDWDM). Prior to that Ori was in charge of the Advanced Technology team, in Cisco's optical group and is the key inventor behind some of the advanced capabilities of Cisco's DWDM product (MSTP). Before joining Cisco in 2002, he was a Senior Systems Architect for Nortel Networks' MEMS based photonic crossconnect product. Before joining Xros/Nortel, Ori was the Systems and Software Architect for the Optical Networking Group at Tellabs, where he architected the first commercial mesh DWDM system (TITAN 7100). Prior to that, he performed early optical networking research at IBM Research. Ori has authored over 40 papers in international conferences and journals and over 15 patents on optical networks. He served on the program committee of OFC, INFOCOM and other conferences and has been the technical co-chair of Broadnets and IPoP. He also serves as an editor for several international journals such as JSAC. Ori has been an invited speaker at many panels, tutorials and several plenary sessions and has been teaching several short courses at OFC. Ori holds a Ph.D. degree from the Technion, Israel.
