摘要
针对当前发布/订阅路由算法普遍缺乏QoS路由保障,引入QoS保障策略,提出了带QoS约束条件的路由准则,基于此准则,提出了一种生成树转发和逆向路径转发混合路由算法。该算法克服了一般发布/订阅路由算法大量冗余信息转发的缺陷,提高了网络效率,降低了网络时延。仿真试验结果表明,该算法在网络时延和效率方面较以前的算法有较大的提高。
Considering the lack of the strategy of QoS routing in the current publish/subscribe routing algorithms,this paper presents a spanning tree forwarding and reverse path forwarding hybrid routing algorithm,which introduces a strategy of QoS preservation and QoS constraint condition.This algorithm overcomes the limitation of redundant information forwarding,reduces the network delay and improves the network efficiency.Simulations show that the algorithm has greater improved than the previous algorithm in the network delay and efficiency.
