Unfortunately, P2P file sharing system has several shortcomings on performance over asymmetric networks, due to two main problems: Fractional Upward Bandwidth and Blockage of Acknowledgement. We propose a new UDP-based protocol to alleviate the problems. Experiments show that our proposed protocol can improve its performance. |
