Data Distribution Algorithm with Out-of-order Feedback for CMT over Diversity Network

Abstract: The performance of CMT degrades remarkably when a large quantity of out-of-order packets are blocked in the receive buffer due to the discrepancy of paths in terms of performance.Based on the analysis of different network configurations,a performance evaluation model was proposed.Meanwhile,a data distribution algorithm was proposed to improve the performance of CMT over diversity paths.This algorithm dynamically adjusts the transmission ratio with the out of order feedback of receiver buffer and reduces the impact of path with bad performance.The result of analysis and simulation reveals that the performance of our scheme outperforms the original round-robin scheme.
