【 摘 要 】

This report describes an implementation of a TCP-like protocol that runs over UDP. This TCP-like implementation, which does not require kernel modifications, provides a test harness for evaluating variations of the TCP transport protocol over the Internet. The test harness provides a tunable and instrumented version of TCP that supports Reno, NewReno, and SACK/FACK. The test harness can also be used to characterize the TCP-performance of a network path. Several case studies illustrate how one can tune the transport protocol to improve performance.
