Structure 2010: Akamai “Doing Terabit Events” (Thanks, World Cup). Akamai are an interesting company which highlights the problems of latency within the cloud. But also check out the work going on in Stanford on OpenFlow http://www.openflowswitch.org/ which provides a similar in data-centre / campus level network latency response by centralising the control of the network routers/switches to best manage the flow of traffic. This work also reduces the complexity of the network and allows a more specific and intelligent  networking flow than achievable by existing routing tables.
