DVPTCP: A Delay-Driven Virtual Parallel TCP for High-Speed and Lossy Networks

The growing diversification of network architectures and application demands results in poor performance of most existing TCPs, especially in large bandwidth-delay product (BDP) and lossy networks. To tackle this problem, we propose a novel delay-based congestion control algorithm, named DVPTCP, whi...

Zusammenfassung:The growing diversification of network architectures and application demands results in poor performance of most existing TCPs, especially in large bandwidth-delay product (BDP) and lossy networks. To tackle this problem, we propose a novel delay-based congestion control algorithm, named DVPTCP, which estimates the network congestion level by using round-trip time (RTT) and adjusts the number of virtual parallel streams dynamically. Related theoretical analyses about throughput and TCP-friendliness are given in detail. According to our extensive simulation tests, our proposal can achieve better bandwidth utilization and TCP-friendliness than the compared schemes in large-BDP and lossy networks.
