摘要
针对铁路企业网络架构存在的内外网物理隔离的设计约束,文章提出用于构建铁路云视频会议系统的音视频安全交换技术,能够实现铁路企业内网、外网与互联网融合接入的云视频会议系统,并重点描述音视频安全交换技术的跨网传输机制和安全保障体系。测试表明,使用该技术可实现铁路云视频会议系统音视频数据在内外网间安全高效实时传输,支持内外网同时组会,能够满足铁路日常会议、应急指挥等应用场景需求,为铁路数字化转型提供关键技术支撑。
In response to the design constraints of railway enterprise's network architecture,physical isolation between the internal and external networks,this article proposes a video and audio security exchange technology for building the railway cloud video conferencing system.This technology enables the cloud video conferencing system to integrate railway enterprise's internal network and external network,as well as the Internet.The article focuses on describing the cross-network transmission mechanism and security guarantee system of the audio and video security exchange technology.Tests have shown that using this technology the railway cloud video conferencing system's video and audio data can be transmitted in a secure,efficient,and real-time manner between railway enterprise's internal and external networks,thus supporting simultaneous group meetings between the internal and external networks and meeting the application requirements of daily railway meetings and emergency command,providing key technical support for the digital transformation of railway.
