3G流媒体系统性能评估与仿真平台

摘要

With increasing improvement of 3G network construction, video streaming services will become one of the main value-added services. However, to individually evaluate the performance of new applications and network standards makes the work repetitive and increases the cost as well. To solve the problem, a performance evaluation and simulation platform for 3G-based video streaming systems is proposed in this paper. The system is highly flexible, users can evaluate the impact of distribution policy and networks status on the quality of service with less cost by modifying the configuration. Moreover, a simulation example for reference based on CDMA 2000 1xEV-DO Rev. A network is implemented upon the platform. The system is meaningful for proper technologies selection and services development of business operation support platforms.%随着3G网络建设的日益完善,流媒体业务将逐渐成为主流的增值业务之一.然而,为新的应用和网络标准进行单独的性能评估工作重复且增加成本.针对此问题,提出一个面向3G网络的流媒体性能评估与仿真平台.该系统具有高度的灵活性,用户可以通过调整配置,以较小的代价评估分发策略和网络状况对服务质量的影响.在系统之上,还给出了一套基于CDMA 20001xEV-DO Rev.A网络的参考仿真实现.该系统对于业务运营支撑平台的技术选型及业务发展具有一定的参考意义.
