UCSD cloud computing project named 1 of "25 radical network research projects you should know about"

NetworkWorld just came out with a "25 radical network research projects you should know about" list. The bandwidth control in the clouds research project from UC San Diego's computer science department made the list.

Here is the main idea of the award winning paper:

If half your company’s bandwidth is allocated to your mirror in New York, and it’s the middle of the night there, and your sites in London and Tokyo are slammed, that New York bandwidth is going to waste. UC San Diego computer scientists have designed, implemented, and evaluated a new bandwidth management system for cloud-based applications capable of solving this problem.

The UCSD algorithm enables distributed rate limiters to work together to enforce global bandwidth rate limits, and dynamically shift bandwidth allocations across multiple sites or networks, according to current network demand. "

The UCSD computer scientists presented this work at the premeir networking conference last year, SIGCOMM 2007, where it won the 2007 SIGCOMM best student paper award – the top prize at the conference. (Congrats to Barath Raghavan)
