Speaker: Prof. Jon Crowcroft Zero Carbon Networking
Title: Zero Carbon Networking
Abstract:
In the UK funded INTelligent Energy awaRe NETworks project http://www.internet-project.org.uk/ we are starting to look at how to reduce the carbon cost of the Internet to zero. In this talk, I will describe the three core aspects to our research plan: firstly we replace as much as possible of the electronics in access and core networks with photonics; secondly, we make use of energy proportional rate and route adaption through feedback mechanism about power usage based on the ideas in the IETF Congestion Exposure research; finally, we migrate services through fast VM and data burst switching to sites co-located with renewable energy resources where there is current overproduction - for example wind farm or tidal barriers. The overall goal is to produce models that are analogous to co-optimising two networks, one for communications and services, the other for energy - and are analogous to co-optimising two networks, one for communications and services, the other for energy - and taking advantage of the observation that transmission of power over a distance is far more lossy than data.
