面向SON的QoS重路由机制

随着计算机网络的发展，自组织网络因其具有灵活性、自适应性、顽健性等优点而受到广泛的关注。在OSPFv3协议的基础上，添加了QoS state交互报文，用于建立邻居信息表，进而完成链路上服务质量QoS的信息存储和重路由触发的判断，并引进了节点的休眠、苏醒等生物特性行为。为保证网络状态变化下应用的QoS，采用了混合式重路由机制，针对不同网络失效状况作出相应的处理。仿真实验表明，该路由机制具有良好的性能。

QoS rerouting mechanism for SON

Along with the development of computer network,SON(self-organizing network)has attracted wide attention with its flexibility,adaptability,robustness.On the basis of OSPFv3,the interactive message of QoS state was defined to establish the information table of neighbors,store the link QoS information,judge the triggering of rerouting,and then the biological behaviors,such as hibernation and awakening,were introduced to the routing nodes.A hybrid rerouting mechanism was adopted to make the corresponding treatment under various network failure situations,so that the application QoS support could be provided when the network state was changing.Simulation results show that the proposed mechanism has better performance.
