摘要
针对Web实时通信(WebRTC)技术,提出一种WebRTC实时通信服务的改进设计方案。方案在客户端侧、服务端侧、客户端与服务端之间的通信等部分对WebRTC进行了改进。改进方案采用了HTML5 WebSocket技术、媒体协商与合成技术、网络地址转换(NAT)/防火墙穿越技术、基于会话发起协议(SIP)栈的信令交互技术、P2P通信安全技术,较好地解决了跨浏览器运行、对客户端侧处理能力的过分依赖和带宽消耗等问题,提高了系统的可扩展性。
This paper describes an improved design for WebRTC technology.With this design,WebRTC communication at client side,server side,and between these two sides is improved.HTML5 WebSocket,media negotiation and synthesis,network address translator（NAT）/firewall traversal,Session Initiation Protocol （SIP） signaling interaction,and P2P communication security are used in this improved design.These solve problems such as cross-browse running,over-reliance on the client-side processing,and bandwidth problems.With this design,they can be made more scalable.
