通信企业“三网融合”方案设计研究

Design of the Convergence of Three Networks for Communication Enterprises

随着经济和技术的发展,传统的业务服务已经不能满足人们的需求,"三网融合"已经成为网络业务发展的必然趋势。通过对"三网融合"国内外现状的研究,分析了当今"三网融合"面临的问题,结合通信企业的实际情况,提出采用分布式流媒体技术进行通信企业"三网融合"方案设计,并针对不同规模通信企业,提出了紧凑型组网、城域网本地组网、多级分布式组网三种组网方案。该"三网融合"设计方案可以有效地节省骨干网带宽、保证QoS,提高用户满意度,对各级通信企业搭建多媒体数据中心具有一定推广作用。

With the economic and technological development, traditional service cannot meet people＇s requirements, so the convergence of three networks has become a tendency of network service development. Through the research on the convergence of three networks at home and abroad, this paper analyzes the problems for convergence of three networks at present. Based on the actual conditions of communication enterprises, the paper proposes the scheme adopting distributed streaming media technology for communication enterprise＇s convergence of three networks, and then it presents three networking schemes for different scale communication enterprises., the compact networking, the local networking of metropolitan area network, and the multilevel distributed networking. These schemes that effectively save the bandwidth backbone network guarantee the Qos and promote the users＇ satisfaction, and they would help the communication enterprises at all levels to build multimedia data center.
