Transit Portal Featured in Technology Review

Leave a comment

Ph.D. student Valas Valancius has been developing the Transit Portal, software that gives services hosted on cloud infrastructures like Amazon EC2 direct control over inbound and outbound traffic.  Different services may have different service requirements: some services may require connectivity that satisfies strict performance requirements (e.g., interactive services or gaming may require low latency or packet loss), while other services might wish to simply use the least expensive connectivity.  Unfortunately, today’s cloud providers select the same routes for every service hosted on the cloud infrastructure (effectively doing “one size fits all” routing for all hosted services).

The Transit Portal allows each service hosted in a cloud to perform its own Internet routing.  For more information on Transit Portal, see the full paper, or check out the following articles:

 

Professor Nick Feamster also blogged about the Transit Portal here.  Lots of information about Transit Portal, including information about how to install a Transit Portal yourself, is available on the GENI project wiki for Transit Portal.

Nick Feamster is a professor in the Department of Computer Science at Princeton University. Before joining the faculty at Princeton, he was a professor in the School of Computer Science at Georgia Tech. He received his Ph.D. in Computer science from MIT in 2005, and his S.B. and M.Eng. degrees in Electrical Engineering and Computer Science from MIT in 2000 and 2001, respectively. His research focuses on many aspects of computer networking and networked systems, including the design, measurement, and analysis of network routing protocols, network operations and security, and anonymous communication systems. In December 2008, he received the Presidential Early Career Award for Scientists and Engineers (PECASE) for his contributions to cybersecurity, notably spam filtering. His honors include the Technology Review 35 "Top Young Innovators Under 35" award, a Sloan Research Fellowship, the NSF CAREER award, the IBM Faculty Fellowship, and award papers at SIGCOMM 2006 (network-level behavior of spammers), the NSDI 2005 conference (fault detection in router configuration), Usenix Security 2002 (circumventing web censorship using Infranet), and Usenix Security 2001 (web cookie analysis).
