摘　　要：为了保证企业级视频会议的服务质量,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,提高企业级网络的利用率,设计了一种变带宽的企业级视频会议动态资源预约算法。该算法综合考虑了不同的视频会议场景、会议阶段和会议终端能力,根据链路的实时带宽计算开销,进而为视频流求得满足时延约束的最佳路径。仿真结果表明,该方法能有效地提高企业网的链路的利用率,保证视频会议的服务质量。In order to guarantee the service quality of enterprise-level video conference,solve the problem that the traditional router network based on RSVP resource reservation protocol cannot meet the real-time management of video service,and improve the utilization rate of enterprise-level network,an enterprise-level video conference dynamic resource reservation algorithm with variable bandwidth was designed.The algorithm takes into account different video conference scenarios,different stages of conference and different terminal capabilities,according to the real-time bandwidth computing overhead of the link,and then finds the optimal path to meet the delay constraint for the video stream.The simulation results show that this method can effectively improve the utilization rate of enterprise network link and guarantee the service quality of video conference.
