Comparison of TCP to XCP performance on channels with correlated errors employing error correction and interleaving
B. Ganguly, V. Mehta · 2005
This paper compares the performance of the TCP and XCP transport protocols over a lossy, large bandwidth-delay link. The link employs block-based error correction codes ECC, along with interleaving which seems to affect both TCP and XCP bandwidth utilization performance. The results are obtained by numerical simulation of TCP and XCP connections over the channel. Single connection results show that the delay introduced by interleaving significantly affects TCP performance, while XCP performance is somewhat better. However, when large interleavers are employed, both protocols suffer. This is likely due to decorrelation of packet errors introduced by interleaving.
