以前对QoS路由的研究大多采用的是平面网络,即所有路由器都在同一级内,一般称之为平面QoS路由;与之相对应的还有分级QoS路由,其基本思想是将路由器分成多个逻辑组,每个组又可包含更小的组。文章对基于蚁群算法的分级QoS路由问题进行了研究。
Most of the previous studies on QoS routing used a flat network, that is, all the routers are in the same level, which is generally called a plane QoS routing. Correspondingly, hierarchical QoS routing is also adopted. The basic idea is to divide the router into multiple Logical groups, each group can contain smaller groups. This paper studies the hierarchical QoS routing problem based on ant colony algorithm.
