TCP Throughput

TCP Throughput

The objective of this test is to find the TCP throughput based on the
successfully transported bytes over the test time. Two units running a TCP
Throughput test are required. One unit will act as the source (Local) and
the other one as the destination (Remote).

The local unit starts sending TCP segments using the Initial Window Size
defined. The window size is adjusted following the TCP algorithm. The
window size is incremented until the Maximum Window Size or
congestion is reached. However, the window size will be reduced when
congestion occurs, then incremented again as described above when the
congestion is cleared. TCP Throughput and windows size statistics will be
gathered throughout the test.

Typical TCP Throughput test application:

Supported Interfaces/Rates: 10M to 1G.
