摘要 针对TCP/AQM对偶性模型采用梯度投影方法调整链路价格收敛速度慢的问题,使用具有更快收敛速度的BFGS方法来进行链路价格的计算,提出一种基于BFGS方法的拥塞速率控制算法。仿真结果证明,利用BFGS方法所设计拥塞速率控制算法具有更快的收敛速度,算法性能优于其它算法。 Aiming at the problem that gradient projection method for adjusting the link price is slower convergence in TCP/AQM dual model,the BFGS method with a faster convergence rate is used to calculate the link price and a congestion rate control algorithm by using BFGS method is presented in this paper.The simulation results successfully show that the proposed algorithm has the advantages over other algorithms of faster convergence rate and good performance.
