摘要
针对变结构拥塞控制协议(VCP)存在着收敛速度慢、公平性差等方面的不足,提出一种简化了的VCP数学模型,并对VCP协议的收敛时间长、公平性差进行分析,通过仿真表明该模型的正确性,具有很好的扩展性,适合于研究AIMD对VCP协议的收敛性和公平性的影响,提出了一些改进VCP性能的方法。
Aiming at some disadvantages of Variable-structure Congestion control Protocol （VCP） in convergence and fairness,a mathematical model that is simplified from VCP is proposed.Convergence and fairness of VCP are anatomized through the model. The simulation result shows that the model is not only right,but also has good expansibility which is particularly suitable for studying the influence of AIMD on convergence and fairness of VCP.Some advice is given to enhance performance of VCP.
