Implementation and evaluation of a new TCP loss recovery architecture

Abstract

In this article, we propose a novel loss recovery algorithm of transmission control protocol (TCP) using packet transmission order, which shows a steady loss recovery ability even though packet loss rate increases. This leads to a significant throughput increase of TCP with heavy packet loss. We have verified the performance increase of the new TCP under various environments such as a wireless network, and multimedia transmission through simulation. Moreover, we implemented the proposed idea in Linux and conducted some experiments in a real environment. Even though the experiment results did not perfectly agree with the simulation results, we obtained a similar throughput increase to that of the simulation. © 2012 Kang et al.
