NF-TCP: A Network Friendly TCP Variant for Background Delay-Insensitive Applications
Delay-insensitive applications, such as P2P file sharing, generate substantial amounts of traffic and compete with other applications on an equal footing when using TCP. Further, to optimize throughput, such applications typically open multiple connections. This results in unfair and potentially poor service for applications that have stringent performance objectives (including sensitivity to delay and loss). In this paper, the authors propose NF-TCP, a TCP variant for P2P and similar delay-insensitive applications that can afford to have communication in the "background". NF-TCP aims to be submissive to delay-sensitive applications under congestion.
