摘要:TCP Vegas may considered as a better alternate congestion control algorithm over TCP Reno, it has still its own issues when it is implemented in wide area emulator. TCP Vegas still has a few obstacles for it to be deployed in the Internet. Studies have shown unfair treatment to Vegas connections when they compete with Reno connections. Other issues identified with TCP Vegas are problems of rerouting, persistent congestion, and discrepancy in flow rate tied with starting times and link bandwidth. Here these issues were investigated and proposed modifications to the congestion avoidance mechanisms of the TCP Vegas, with the slow start and congestion recovery algorithms of Vegas remaining untouched. Our solution is neither dependent on any other critical dependent parameter values nor on the buffer management scheme at the routers (e.g., RED). Our experiments show that the proposed TCP PIPE (modified version of TCP Vegas) is able to obtain a fairer share of the network bandwidth when competing with other TCP flows. At the same time, our experiments prove that TCP PIPE preserves the properties of Vegas that have made it a striking
