摘要: 在动态网络中,显式控制协议(XCP)带宽设置不当会使链路利用率大幅下降。针对该问题,提出一种基于滑模控制的XCP带宽补偿算法FC-XCP,通过设计合理的控制器,使输出带宽与链路带宽相匹配、网络系统更稳定。仿真结果表明,与PII-XCP算法相比,FC-XCP能明显提高动态网络的带宽利用率。

Abstract: It is difficult to set reasonable output bandwidth in dynamic network for Explicit Control Protocol(XCP), and unreasonable settings of bandwidth will cause the link utilization declining, so this paper proposes a compensation algorithm of XCP bandwidth named FC-XCP. By reasonable controller design, it solves the problem of bandwidth mismatching when the XCP dynamic changes. Simulation experimental results show that compared with PII-XCP, FC-XCP can improve the bandwidth utilization effectively in dynamic networks.
