Mobile Internet WebRTC and Related Technologies

This paper describes an improved design for WebRTC technolo- gy. 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 all used in this improved design. This solution solves cross- browser running problem of WebRTC applications, reduces reli- ance on client-side processing capability, and reduces band- width consumption. With this design, WebRTC also become more scalable.
