单网卡 MCU 内网及联通电信双线公网实现视频会议方法

摘要

The article analyzed the network deployment mode of video equipment and the principle of common NAT not be-ing able to convert to H.323 protocol,introduced three NAT conversion modes of H.323 protocol penetrating gateways and firewalls,gave two topological structures and setting process and methods of achieving Duplex-line video conferences of in-tranet and public network with single signal port MCU and provided an economic and effective solution for constructing video conference systems for large-scale construction enterprises with projects distributing throughout the country.%分析视频设备的网络部署方式及普通 NAT 无法转换 H．323协议的原理，介绍了 H．323协议穿透网关、防火墙的3种 NAT 转换方式，给出单信令口 MCU 采用负载均衡和双路由作为网关实现内网、公网双线路视频会议的两种拓扑结构及其设置过程和方法，为分布在全国各地项目部的大型施工企业建设视频会议系统提供了经济、有效的解决方案。
