Paper Abstract

This paper investigates the performance of single and multiple TCP connections sharing a bandwidth-delay link. The link employs block-based error correction codes ECC, along with interleaving which is first shown to affect the performance of a single TCP connection. We examine impact of using ECC and interleaving on multiple connections on an ideal two-state fading channel model. Results are obtained by numerical simulation of both single and multiple TCP connections over the channel. Single TCP connection results show that the delay introduced by interleaving significantly affects TCP performance on a lossy channel. Without ECC, the aggregate channel utilization of multiple instances of TCP is higher than that of a single TCP instance. We find that this advantage dissipates when significant ECC is introduced.
