Firewall traversal method, equipment and system based on web page browser communication

Abstract

The invention provides a firewall traversal method, equipment and system based on web page browser communication. A source terminal sends signaling messages including port limited signs to a WebRTC server, sign information of a first port and a media stream corresponding to communication interaction are sent to a corresponding second port of a websocket server according to the address information of the websocket server in signaling response messages fed back by the WebRTC server and the sign information of the first port, the second port belongs to an open port corresponding to the source terminal, the websocket server forwards the media stream to a target terminal through a port corresponding to the sign information of the first port according to the address mapping relation which is stored in the WebRTC server and corresponds to the sign information of the first port, therefore, firewall traversal based on the web page browser communication in enterprise networks is achieved, communication safety of enterprise intranets is guaranteed, meanwhile, and flexibility of communication services and the compatibility and coupling degree of existing communication services are improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular to a method, device and system for traversing a firewall based on web browser communication. Background technique [0002] With the development of the Internet and the release and deployment of HTML5, web browsers can realize web real-time communication (Web Real-Time Communication, WebRTC). WebRTC is a technology that supports web browsers for real-time voice conversations or video conversations. Web page video conferencing, the standard is the web page hypertext application technology protocol, the purpose is to provide real-time communication (Real-Time Communications (RTC)) capabilities through the browser to provide simple javascript, this technology is widely used in enterprise networks. [0003] However, in the enterprise network, in order to ensure information security, firewalls are usually used to restrict certain ports of employees' com...

Problems solved by technology

[0003] However, in the enterprise network, in order to ensure information security, firewalls are usually used to restrict certain ports of employees' computers, for example, only port 80 is allowed.

Therefore, when an employee uses the real-time communication function based on a web browser on his own computer, that is, the source terminal, to communicate with a target terminal outside the corporate network, if the dynamic communication port negotiated by the source terminal and the target terminal through the web real-time communication WebRTC server is blocked by the firewall restrictions on the use of the device, it is impossible to directly conduct voice or video communication between the source terminal and the target terminal
