基于TCP协议的网络拥塞控制算法设计

通过对以往经典的TCP拥塞控制算法的总结和对比，从信道利用率、通信稳定性和公平性三方面出发，设计了一个改进的TCP拥塞控制算法。利用数学建模方法，简化并模拟实际的网络通信，运用数理统计和概率论的知识分别得出经典拥塞控制算法和改进拥塞控制算法实验结果的数学期望和方差，从信道利用率、通信稳定性和公平性三方面进行对比，证明改进算法的有效性。

The Design of Network Congestion Control Algorithm Based on TCP Protocol

Through the past, classic summary and comparison of TCP congestion control algorithms, from the channel uti- lization, communication stability and fairness of the three areas, design an improved TCP congestion control algorithm. U- sing mathematical modeling methods to simplify and simulate real network communication, use mathematical statistics and probability theory knowledge obtain the mathematical expectation and variance of the classic congestion control algorithm and improved congestion control algorithm experimental results. Contrast from the channel utilization, communication sta- bility and fairness, to prove the effectiveness of the improved algorithm.
