中文摘要：

为了消除由于互联网异构性而导致的性能瓶颈，解决当前互联网流媒体系统所面临的服务能力不足问题，本文设计了一个以应用层流媒体技术为基础的实时流媒体传榆框架，构建了由网络视频服务器（NVSs，Network Video Servers）和代理服务器（Proxy Servers）组成的视频服务组，并为多用户提供服务．提出一个基于蚁群算法的有效用户接入算法，在满足用户视频请求的基础上，实现了用户接入数目的最大化，提升了系统容量．

英文摘要：

In order to eliminate performance bottlenecks caused by the heterogeneity of Intemet,and to solve the current the shortage problem of service capability within the streaming media system, this paper proposed a real-time streaming media transmission frame- work, built on the application-layer based flow media technology. Specifically, the framework is constructed by multiple Network Vide- o servers （ NVSs } and Proxy Servers, composing the video service group and providing service for users. In this paper, we proposed an effective user access algorithm based on ant colony algorithm, which can maximize the number of user access with the satisfactory user video quality requirement and increase the system capacity.
