Here is the abstract from the Technical Report describing our work: "We describe an instrumentation of TCP/IP that monitors different aspects of a TCP connection, provides information about its performance, and displays relationships between a variety of variables that reflect the state of the connection. We define interface events for a TCP/IP connection, describe how traces are obtained, how application processes initiate trace collection, and how performance parameters are computed from these traces. Data presentation tools are provided to generate different types of graphs. The instrumentation has been done on a SUN 3/50 running UNIX (SUN OS 3.0 with 4.3BSD networking code)."
