Matt Mathis

ORG Pittsburgh Supercomputer Center Title BIO Matt Mathis is dedicated to the idea that an ordinary user running an ordinary network application on an ordinary workstation should either saturate some workstation bottleneck or completely fill some network link. He has been working on understanding and improving Internet performance for the last 10 years. His contributions include the "square root of loss rate" TCP performance model, the TCP Selective Acknowledgment option, and early work in TCP autotuning. He is currently chief architect for the Web100 project which is developing production quality TCP performance instrumentation and autotuning for TCP. His new projects include developing tools that use instrumented TCP to better diagnose problems with long Internet paths and improving path MTU discovery, to foster raising the deployed MTU in the production Internet.
