Accountable Internet Protocol (AIP)

This upcoming SIGCOMM 2008 paper describes the overall AIP architecture. AIP provides a solid foundation of accountability for future Internet designs through its use of a self-certifying addressing structure. AIP greatly simplifies the task of securing additional parts of the network infrastructure.

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

Similarity Enhanced Transfer

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.
