摘　　要：为了解决传统路由器网络基于RSVP资源预留协议无法满足视频服务的实时管理的问题,提出一种面向SDN网络的动态资源预约算法.该算法根据链路的实时可用带宽计算链路开销,进而获得满足时延约束的最优路径由于目前的互联网为多自治域管理,而多自治域的管理较为困难,主要研究了单自治域的应用.场景:大型校园网和企业网仿真测试结果表明,对于一个具有20个左右核心路由器的大型校园网的情况该算法能够达到良.好的预约效果.该算法对大型校园网开展具有QoS服务质量保证的视频会议服务具有较大的现实意义.To solve the problems that traditional router network cannot meet the real-time management of the video service based on RSVP resource reservation protocol,a dynamic resource reservation algorithm based on software definition network( SDN) is proposed. The link cost is calculated according to the real-time link available bandwidth,and then the optimal path satisfying the delay constraint is obtained. Since the current Internet is managed by multi-autonomous domains and the management of multi-autonomous domains is difficult,the application fields of single autonomous domains,large campus network and enterprise network are mainly studied. Simulation results show that a good booking effect can be achieved for a large campus network with twenty or so core routers.The algorithm has great practical significance for large campus network to carry out video conferencing service with QoS guarantee.
