We present the 1993 annual report on research efforts of the San Diego Supercomputer Center's Applied Network Research group (ANR). Our projects were undertaken in collaboration with the Computer Systems Laboratory of the University of California in San Diego (CSL), as well as a number of other researchers across the country.

This year, we continued our research on network analysis and modeling, as well as advanced network technologies including the CASA gigabit testbed. Our research topics include issues of network access, instrumentation for the accurate gathering of performance statistics, accounting, and quality of service in the Internet.

We hope interested parties within the Internet research community will find this report helpful in understanding our research agenda. We also wish to use this report to stimulate further discussion and interaction among researchers pursuing similar projects and goals.
