Available Bandwidth Measurement Via TCP Connection

Tags:
bandwidth issues

Overview This paper introduces a novel mechanism for actively measuring available bandwidth along a network path. Instead of adding probe traffic to the network, the new mechanism exploits data packets transmitted in a TCP connection (inline measurement). The paper calls a modified version of TCP that incorporates the proposed mechanism ImTCP (Inline measurement TCP). ImTCP is based on Reno TCP, with a modification to the sender program only. The ImTCP sender adjusts the transmission intervals of data packets, then estimates available bandwidth of the network path between sender and receiver utilizing the arrival intervals of ACK packets.
