Inline Network Measurement: TCP Built-In Techniques for Inferring End-to-End Bandwidth

Overview This paper introduces a method for measuring the available bandwidth in a network path between two end hosts using an active TCP connection. First it constructs a new measurement algorithm that uses a relatively small number of probe packets yet provides periodic measurement results quickly. Then it applies the proposed algorithm to an active TCP connection and introduced ImTCP, a version of TCP that can measure the available bandwidth. ImTCP is evaluated through simulation experiments and found that the proposed measurement algorithm works well with no degradation of TCP data transmission speed. It also introduces examples of ImTCP special transmission modes.
