摘要

本文提出了一种预测性队列管理方法,用于互联网路由器在通信延迟情况下的受限拥塞控制。该方法利用队列和路由器模型、输入流量速率和队列长度来精确描述整个过程。然后,利用所建立的模型,采用模型预测控制方法,构建最佳受限主动队列管理(CAQM)策略。我们选择了一些重要因素,如链路容量、传输控制协议(TCP)会话、往返时间和其他一些因素,并利用这些因素将 TCP 的互连线性化。然后,设计了一种基于 MPC 的高效结构,以便在面临未知干扰时管理 CAQM。仿真验证了建议方法的有效性和鲁棒性。

Optimal congestion management in network routers subject to constraints, disturbances, and noise using the model predictive control approach

A predictive queue management method is proposed for constrained congestion control in internet routers in the face of communication delays. The proposed method uses the queue and router models, input traffic rate, and queue length to precisely characterise the entire process. The model that has been built is then used to construct an optimal constrained active queue management (CAQM) strategy using the model predictive control method. Important factors, such as link capacity, Transmission Control Protocol (TCP) sessions, round-trip time, and a few others, have been selected and used to linearise the interconnection of TCP. Then, an efficient MPC-based structure to manage the CAQM in the face of unknown disturbances is designed. Simulations are used to validate the proposed method's effectiveness and robustness.
