Improving TCP Performance Over Wireless WANs Using TCP/IP-Friendly Link Layer
Overview This paper proposes the use of a TCP/IP-friendly link level error recovery mechanism with novel design in conjunction with state-of-the-art Transmission Control Protocol (TCP) enhancements to improve TCP performance on network paths involving Wireless Wide-Area Network (W-WAN) links. It shows that by combining a selected set of TCP enhancements TCP performance is significantly improved over W-WAN links. In addition, the paper employs a TCP/IP-friendly link layer protocol which minimizes the additional delay due to the Automatic Repeat reQuests (ARQ) by limiting the number of retransmission attempts and by adding redundancy in the retransmitted frames in a novel way. This paper performs experiments in an emulated satellite environment with a real implementation of the TCP/IP-friendly link layer and TCP enhancements in Linux.
