摘要
随着多媒体实时应用的大量涌现,各种应用对服务质量的需求也在迅速增长。SIP协议的出现,为解决多媒体实时应用的QoS问题提供了有效的途径。通过对SIP消息进行扩展,提出了QoS的保证方案,并进行了仿真实验。结果表明,所提方案能有效地改善多媒体通信的QoS性能。
Along with the multimedia real-time application massively emerges, the QoS demand of each kind of application is also rapidly growing. The SIP protocol appears, it provides the effective way for solving the QoS problem of multimedia real-time application. Through the expansion to the SIP news, it proposed the QoS guarantee plan, and has carried on the simulation experiment. The result indicated that, the plan can effectively improve the QoS performance of multimedia communications.
