ICTON 2011 1ST DAY - Random notes

Plenary Speakers

Professor Biswanath Mukherjee
University of California, Davis


Title
Some "Opaque" Problems in Transparent Optical Networks


Trends: Mixed line rates: 20, 40, 100 Gbps wavelengths. (needed for hierarchical grooming)
Elastic Rate networks.
Traffic Engineering: put the traffic where the bandwidth is.
Network engineering: put the bandwidth where the traffic is.
Network planning: put the bandwidth where the traffic is fore-casted to be.


Professor Keren Bergman
Columbia University


Title
Nanophotonic Interconnection Networks for Performance-Energy Optimized Computing


Eletronic x Photonic
Eletronic: Buffer, receive, retransmit at every router
Photonic: larger BW of data. Data is streamed once per communication event.

SESSION Mo.B3

A squatting based framework to enhance network virtualization allocation in optical networks (Invited)
X. Hesselbach, N. Naumenko


Physical resource, virtual resource, logical resource.
Using virtualization helps, for instance the slow implementation of Ipv6 while Ipv4 is still in use. Virtualization helps avoiding the ossification of the Internet.
Classes relate to the amount of capacity or granularity of capacities for instance: lambdas, OBS, fibers, 100Gbps, !0Gbps etc. The demand is per type of service not per resource (BW).
With virtualization resource that is being used in one service can be used in another service.


A GRASP-based heuristic to design the GMPLS control plane network topology with resilience guarantees (Invited)
M. Ruiz, L. Velasco, G. Junyent, J. Comellas


A drawback of a minimal topology is the amount of control information per link is higher. (specially in the case of failure)
