提出一种增添能最有效减弱网络社团特性的边以提高Internet网络传输性能的策略,即减弱社团结构策略(WCS策略),并基于光逻辑链路可以提供与实际物理链路相当的高性能,以实现WCS策略的Internet网络的拓扑重构。在伪随机网络、具有社团结构的无标度人工网络和实际Internet网络上分别进行了基于全局最短路径路由和局部路由的实验。实验结果表明,利用WCS策略在社团之间少量边的添加,就能实现网络负载能力和平均最短路径的大幅改善。
An efficient weakening community structure strategy (WCS) by adding links to the existing networks was propose, which could enhance Internet transmission performance. Internet topology reconstruction could be realized by WCS strategy, because lightpaths that represent logical links between nodes could achieve the same high performance as physi- cal links by means of optically bypassing intermediate nodes. The performance of the proposed strategy was investigated in pseudo random networks with community structure, scale-free network with community structure and Internet topol- ogy respectively, for both local routing strategy and global shortest-path routing strategy. The experimental results show that the traffic capacity of networks and the average shortest path are considerably improved by adding a few links among communities.
