面向混合负载的复杂网络路由优化策略
首发时间:2016-11-03
摘要:现有的复杂网络路由策略忽略了混合负载的存在。针对这一问题,本文提出一种面向混合负载的路由优化策略。该策略从实时性的角度,将负载分为特权包和普通包两类。特权包采用最短路径算法建立路由表并约定其在队列中不排队,以保证实时性要求;普通包采用混合优化算法对路由表进行优化,从而使网络吞吐量最大。仿真结果显示,该策略能够保证特权包传输的实时性,同时也大幅度提高了普通包的传输能力。

A optimized routing strategy for hybrid load on complex networks
Abstract:Existing routing strategy on complex network ignores the existence of hybrid load. A novel routing strategy for hybrid load is proposed. Information packets are classified into two categories: prerogative packets and normal packets. The prerogative packets' routing table is built by the routine of shortest path strategy, and we go against the FIFO rule in order to meet real-time performance. The conventional routing strategies for normal packets are not functioning adequately in the presence of privileged packets. In order to avoid nodes overloading, the hybrid optimization algorithm is used to optimize the route set. The new routing can not only enlarge traffic capacity of normal packets, but also enhance traffic efficiency of privileged packets with the smallest path length and the smallest average transmission delay. Compared with previous routing strategies, the new strategy performs more effectively.
