摘要： 拥塞控制不能有效地支持多媒体业务,模糊逻辑提供了解决复杂性、动态性和健壮性问题的一种非解析方法,文章基TCP/IPInternet于模糊算法和区分服务提出了新的拥塞控制机制。与丢尾算法和普通算法相比,在保证的同时,该算法不仅改善了的吞REDIPREDQoSTCP吐量,而且使流量抖动较平缓,并克服了区分服务对连接公平性差的缺点。

Abstract: Current TCP/IP congestion control algorithms cannot efficiently support Internet multimedia services. Fuzzy logic techniques provide a non-analytical approach to design complex, dynamic and robust control schemes. In this paper, a novel IP congestion control mechanism is proposed based on fuzzy RED algorithm and Diff-Serv. Compared with drop tail and normal RED, it not only improves the throughput of TCP with QoS guarantee, but also keeps flow rate changing smoothly. And it overcomes the drawback of unfairness for all connections in the Diff-Serv case.
