【摘要】 介绍了利用Simulink构造的TCP拥塞控制算法和RED算法的连续模型,以及在此基础上建立起来的多个TCP连接竞争一条瓶颈链路的仿真场景。对比实验表明,该模型能够预测稳态时的RED行为,并且只需要很短的运算时间,可以作为大型TCP/RED仿真场景的参数调整工具。更多还原

【Abstract】 This paper introduces the continuous models of TCP congestion control algorithm and RED algorithm built on Simulink, and the simulation scene based on these models with multiple TCP connections competing for a single bottleneck link. Comparing research shows that this model can predict steady-state RED dynamics in very short solving time, which makes it a suitable tool for parameter tuning in large-scale TCP/RED simulation scenes.更多还原
