Figure 1: Behavior of TCP with and without the mechanism - local
Trace data of the simulation of an HTTP server sending data to clients located on one distant computer. The computers used were two HP Vectra XU 6/200 running Linux 2.0.0 and were connected through an AdvanceStack HP J2410A Ethernet switch. The measurement and simulation tools were those described in section 2. The size of the data sent during each TCP connection was 32 KB since it amounts to the largest congestion window size managed by this version of Linux. The x-axis is the time at which a packet was sent. The y-axis is the sequence number of that packet. The lower curve shows the behavior of the conventional implementation of TCP while the upper curve shows what happens when the remembering mechanism is used. There is no artificial delay involved in this graph.
