ABSTRACT:
Disclosed herein is a novel technique that greatly improves the TCP-friendliness of CTCP over such under-buffered network links without degrading the protocol efficiency to utilize the link capacity. Instead of using a pre-defined threshold, the disclosed approach, which may be referred to herein as “CTCP-TUBE,” dynamically adjusts the threshold based on the network setting in which the flow is operating. The backlogged packets of a regular TCP may be estimated along the same path by emulating the behavior of a regular TCP flow in runtime. Based on this, a threshold is set so as to ensure good TCP-friendliness. CTCP-TUBE can automatically adapt to different network configurations and also concurrent competing flows.
