复杂适应系统Internet中的网络流量仿真研究

Study on network traffic simulation of a complex adaptive system-Internet

网络流量与网络带宽的关系是网络研究的一个重要课题,论文用复杂适应系统理论及基于Agent的模拟方法,对Internet复杂适应系统的网络流量与网络带宽的关系进行了模拟仿真,即在Swarm平台上构建了一个基于多Agent的随机网络流量动态模拟系统.在该系统中,首先定义了Agent行为规则及策略,然后通过多个Agent交互作用及多个Agent与周围环境之间的相互作用和影响,模拟出整个系统宏观层次的涌现特征:网络带宽被占用约50%左右时,出现震荡现象.该现象将对下一代互联网的建设提供理论参考.

Study the relation between network traffic and network bandwidth is a critical problem in Internet research. With the application of complex adaptive system theory and agent simulation approach, this article simulates the relation between network traffic of a complex adaptive system-Internet and network bandwidth. That means to build a dynamic simulation system of stochastic network traffic based on multi_(agents.) In this system, firstly, the behaving rules and strategies of agent are defined, and after that, through the simulation of the interact among multi_agents and the interact and inter_influence between (multi_agents) and the environment around them, the network emergence characteristics of the whole system on the macro-scale is simulated: when the network bandwidth is used up to 50%, the phenomenon of concussion will appear. And this phenomenon will give a reference to building Internet II.
