基于链路容量的核心网拥塞自动控制研究

针对传统核心网拥塞自动控制方法存在的核心网吞吐量较低,网络延时时间较长以及控制效果不佳的问题,提出基于链路容量的核心网拥塞自动控制方法。利用四元组建立核心网数学模型,描述核心网拓扑结构,根据拥塞阈值识别核心网拥塞状态,并根据链路容量对核心网数据传输速度和拥塞窗口大小进行调节,控制链路数据传输量,以此实现基于链路容量的核心网拥塞自动控制。经实验证明,在设计方法应用下核心网吞吐量可以达到192.65Mbit/s,网络延时时间为0.46s,具有较好的核心网拥塞自动控制效果。

Aiming at the problems of low throughput, long network delay time and poor control effect of traditional core network congestion automatic control methods, an automatic core network congestion control method based on link capacity is proposed. The mathematical model of the core network is established by using quaternions to describe the core network topology, identify the core network congestion status according to the congestion threshold, adjust the core network data transmission speed and congestion window size according to the link capacity, and control the link data transmission volume, so as to realize the automatic control of the core network congestion based on the link capacity. The experiment proves that the core network throughput can reach 192.65 Mbit/s and the network delay time is 0.46 s under the application of the design method, which has a good core network congestion automatic control effect.
