摘 要

近年来，随着一浪高过一浪的信息化建设浪潮，宽带网络得到了快速的发展和普及，电信业务正由窄带语音业务向宽带数字综合业务发展。视频业务作为宽带数字综合业务的一种，已成为当前发展最快的多媒体通信形式。在经济全球化的趋势下，企业之间的竞争越来越激烈，对于中国企业来说首要解决的问题就是提高企业运转效率。视频通信将是提高企业运转效率的重要手段之一。为尽一步发挥联通数据网的综合优势，中国联通适应市场需求, 推出了基于ATM+IP技术的会议电视业务。

本论文分析和讨论视频会议系统承载网的发展、各种方案的优点、缺点。结合中国联通实际情况，联通视频会议专网采用ATM组成传输网络，由CISCO公司高端路由器构成核心IP网络。以ATM+IP作为组网的核心技术。

本论文结合MCU和GK产品特点，给出了便于联通运营管理、同时也适合联通承载网结构特点的组网方案。从视频交换层设计方案上保证联通组建可运营、可管理、能够提供高质量视频服务的会议电视运营网络。同时针对联通会议电视网间互通的需求，实现了针对不同运营商和不同类型终端的互通目标。最后通过对接入安全、网络和传输安全、计费系统的安全、视频层的安全控制、应用层的安全认证、防止终端避开MCU直接通信等六个方面的设计来保证会议电视业务网安全。

本论文从多个层面上进行设计以保证联通组建可运营、可管理、能够提供高质量视频服务的会议电视运营网络。

Abstract

In recent years, with wave upon wave of information construction wave of

broadband network development and the rapid popularization of telecommunica-tions services by the narrowband voice services to the development of broadband integrated services digital. Broadband video services as an Integrated Services Digital has become the fastest developing multimedia communication forms.

Under the trend of the economic globalization, the competition of of the business enterprise is more and more vigorous, saying the initial problem for resolve for the Chinese business enterprise be raise the business enterprise operation efficiency.The video conference system will be one of the important meanses that raises the business enterprise operation efficiency.For the comprehensive advantage of the to the utmost one-step exertive China Unicom’s data net, the China Unicom adapts the market need, releasing according to the ATM plus IP technical meeting television business.

This thesis analysis and discussion video conference system load the advantage,weakness of the development,various project of the http://doc.guandang.netbine the China Unicom an actual circumstance，a video conference system of China Unicom particularly the net adoption ATM to constitute to deliver the network, constitute the core IP network from the CISCO company high level router.With ATM+ IP is a set of net of core technique.

This thesis combines the MCU and the GK product characteristics, giving a luck camp management,also in keeping with China Unicom a net project that loads the net structure characteristics. Exchange layer from the video program designed to ensure Unicom established carriers can be managed to provide high-quality video conference television operator services network. Unicom meeting at the same time against the demand for interoperability between network and achieve a different operators and the exchange of different types of terminals goal. Finally, the access security, network and transmission security, the security of billing system, video security control layer, application-level security certification, to prevent direct communication terminals avoid MCU six aspects of the design to ensure that the TV business network security.
