Improve HTTP/TCP performance over ATM networks: new schemes and performance comparisons
Chin-Dong Wang, Ruay-Shiung Chang · 2002
This paper proposes a "selective packet retransmission" scheme for improving HTTP/TCP performance when transmitting through ATM networks. In selective packet retransmission, we utilize the property of human's perception tolerance for errors to determine whether to retransmit a corrupted TCP segment or not. For lossable data, such as image, when error occurs because of cell lost, it will not be retransmitted. The simulations show that, for the same buffer size and traffics load, selective packet retransmission results in higher throughput than PPD, EPD, and plain TCP over ATM.
