Network Congestion Control System Modeling and Flow Controller Design

在考虑多回路时延、网络负载动态变化和高优先级业务影响的前提下,基于流体流理论,推导建立了可调服务速率的业务流量控制数学模型,并提出了一种简单实用的流量控制算法,所得出的控制机制适用于高优先级业务和"尽力而为"业务共存的网络环境,较好地克服了网络传输时延的影响,并对该控制机制的稳定性、抗干扰性、鲁棒性和公平性进行了仿真试验。

By considering multi-loop delay, network load dynamic changes and high-priority service impact, we derived a flow control model of variable service rates, and proposed a simple and practical flow control algorithm on the basis of fluid flow theory. The mechanism for high priority service and ＂ best effort＂ transmission delay. The stability service co-existence in network better overcame the impact of , interference, robustness and fairness were simulated.
