Studying the phase transition process from free flow to congested state in communication networks is one of the hot topics of dynamically complex systems, and many related theoretical and computational efforts have been made to improve traffic systems’ organization and load management. A criterion to measure the organization efficiency of the system is the formation process of a global traffic flow cluster from local small clusters in a communication network which can be evaluated by measuring the percolation threshold. While little attention has been paid to percolation in such studies, in this research, the traffic percolation threshold is defined based on the system nodes’ loads to examine the influences of the network structures, different routing strategies, and distributions of transmission capacities on the efficiency of the communication networks. Considering the obtained results, it was found any variation in the network structure and traffic control strategies that leads to a rather diverse load distribution among the system’s nodes can organize traffic loads more efficiently.

基于渗流变换的通信网络流量分析

研究通信网络中从自由流到拥塞状态的相变过程是动态复杂系统的热点课题之一，人们已经做出了许多相关的理论和计算工作来改善交通系统的组织和负载管理。衡量系统组织效率的标准是通信网络中局部小簇形成全局流量簇的过程，可以通过测量渗滤阈值来评估。虽然此类研究很少关注渗透，但本研究根据系统节点的负载定义流量渗透阈值，以考察网络结构、不同路由策略和传输容量分布对效率的影响的通信网络。考虑到所获得的结果，发现网络结构和流量控制策略的任何变化导致系统节点之间的负载分布相当多样化，可以更有效地组织流量负载。
