基于TCP层拥塞避免算法的研究与实现

Research and realization of congestion avoidance algorithms based on TCP

阐述了TCP利用滑动窗口技术进行数据包传输的机制,在拥塞控制方面详细讨论了拥塞避免的相关算法.指出在网络拥塞的情况下,由于超时引起的数据包重传机制对于提高网络的服务质量重要性,通过研究分析传统的快速重传机制和算法,提出了新的解决方案.结果表明,改进后的拥塞避免算法比传统上的算法不仅能够更好的解决拥塞问题,提高网络的传输质量,而且还能够更好的利用网络资源,提高网络的整体性能.

This paper explaines how TCP utilize slip window technology to transfer mechanism of data packet. It has particularly discussed the correlative algorithm to congestion avoidance in the congestion control side. It has also illuminated in condition of network congestion, the service quality significance of improving network according to the influence of grouping overlap transmission mechanism by the overtime. Based on the research and analysis of traditional rapid overlap transmission mechanism and algorithm, it puts forward a new solution.Results show that the improved slow start and congestion avoidance algorithm can not only settle congestion question and improve transmission quality of network better but also make better use of the network resource and improve the whole performance of network.
