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.
