Center for Networked Systems

Plug-and-play data center networks and new diagnostics for router delays are among the computer networking challenges UC San Diego faculty and students, and their sponsor companies, are tackling through the Center for Networked Systems (CNS).The Center, which actively engages eight corporate partners, 20 faculty and nearly 70 graduate students, aims to enhance computer scientists' ability to build robust, secure, manageable, and open networked systems.

Both the data center networking and the router delay projects debuted recently at SIGCOMM 2009, the top conference for computer networking. One Jacobs School team developed an inexpensive solution for diagnosing delays in data center networks as short as ten millionths of second - delays that can lead to multimilliondollar losses for investment banks running automatic stock trading systems.

A second team from the Jacobs School developed software for enabling massive data centers to logically function as single, plug-andplay networks. The software, called PortLand, is a fault-tolerant, layer 2 data center network fabric capable of scaling to 100,000 nodes or more.

Amin Vahdat, Director of the Center for Networked Systems and a computer science professor at the Jacobs School, led the PortLand project, which has garnered considerable interest from industry. "The students are getting good jobs and internships coming out of this project because they have data center networking skills. Companies are looking for this skill set," said Vahdat, who holds the Science Applications International Corporation (SAIC) Chair at the Jacobs School of Engineering.
