A new TCP protocol able to measure bottleneck bandwidth

In this paper, we propose a TCP protocol which can measure the end-to-end bottleneck bandwidth of a path without the network support. This is achieved by exploiting information in acknowledgment packets returned to TCP source. The key innovation is to combine the commonly used transport protocol with the ability to measure the end-to-end bottleneck bandwidth. Simulation studies exemplify the method's accuracy and effectivity in different network environments.
