摘要
IMS作为电力通信行政交换网引进的新技术,在电网企业逐步得到广泛应用,随着新兴通信业务的快速增长,对多媒体流的传输连续性和实时性提出了更高要求。论文介绍了一种基于最短路径的多媒体流路由调度方法,并对多媒体流在传输过程中阻塞概率的变化提出了优化策略,并在此基础上进行了仿真验证,结果表明优化策略在一定程度上可以保证IMS业务的信息传输质量,能够满足电力通信业务对实时性和高质量的需求。
IMS as a new technology of electric power communication exchange network administration introduced,has been applied widely in power grid enterprises,with the rapid growth of new communication services,the multimedia streaming continuity and real-time put forward higher requirements.This paper introduces a multimedia stream scheduling method based on shortest path routing,and put forward the optimization strategy of the multimedia stream changes the blocking probability in the transmission process,and on the basis of the simulation,the results show that the optimization strategy in a certain extent can guarantee the information transmission quality of IMS service,meet the needs of power communication the business of real-time and high quality.
