Efficiency through Eavesdropping: Link-layer Packet Caching

RTS-id is a mechanism by which senders can ask receivers "do you have this packet yet?" before sending them a large packet. This simple, fully-backwards-compatible mechanism can substantially increase throughput both in infrastructure networks and in mesh networks. Appeared in NSDI 2008.

TCP Throughput Collapse in Cluster-Based Storage Systems

This work characterizes the causes of and analyzes several potential solutions to the problem of TCP incast, a catastrophic throughput collapse that can occur when many senders transmit to a single receiver. Incast is a significant barrier to the scaling of cluster-based storage systems. Appeared in FAST 2008

Holding the Internet Accountable

This HotNets 2007 paper sets out a call for an Internet architecture based on an accountable foundation based on self-certifying addressing.

Research

My research interests are in computer systems in the networked environment. I have a particular interest in resilient distributed systems that perform well under a variety of adverse network conditions, and in network measurement.
