Yi Wang     Ph.D Department of Computer Science Princeton University Address: Department of Computer Science 35 Olden Street Princeton, NJ 08540-5233 Email: yiwang at cs dot princeton dot edu [Research] [Publications] [Courses]

I received my B.E and M.E degrees in Electrical Engingeering from Tsinghua University, Beijing, China in 2003 and 2005, respectively. I worked in the New Generation Network Laboratory under the direction of Professor Xing Li.

Research

• Internet Routing
• Network control and management
• Measurement and performance analysis

Projects:

• Neghbor-Specific BGP (NS-BGP): a new route selection model in which a router can flexibly choose different BGP routes for different neighbors. We proved a surprising result that the much more flexible NS-BGP is guaranteed to be stable under much less restrictive conditions on how routers "rank" the candidate routes. (In fact, we proved that the "prefer customer" condition in the "Gao-Rexford" conditions" is no longer needed.) We also show that it is safe to deploy NS-BGP incrementally, as a routing system with a partial de- ployment of NS-BGP is guaranteed to be stable, even in the presence of failure and other topology changes.
• VROOM (Virtual ROuter On the Move): a new network architecture which separates the tight coupling between the physical and logical configuration of routers, and simplifies network management by enabling (virtual) routers to freely move from one physical node to another, without changing the IP-layer topology.
• Morpheus: a modular, open routing platform that supports flexible control of interdomain routing policies for a backbone network.
