Design And Implementation Of Whiteboard Implementation Mechanism Based On Webrtc

With the rapid development of Internet technology, the Internet has entered the mobile Internet era. A wide variety of network applications have been developed quickly. The maturity of HTML5make the Web front-end development entered a new era. Web application has more advantages to the Native application. Meanwhile, the extension of the Internet and other industries such as health care, education, and other traditional industries have been gradually begin to merge. Google’s open source technology WebRTC (Web Real-Time Communication) technology will have a tremendous impact on the current Internet industryThis paper studies the technologies of WebRTC, HTML5,WebSocket and Node.js. And elaborates the characteristics and advantages of these technologies and their influence for the Internet industry. By research of the general flow of business meetings and staff training,this paper has developed the web whiteboard demands. The web whiteboard system is divided into three main parts which are whiteboard component, room management module and other functional modules.By using WebRTC and HTML5technology, this paper has built a whiteboard application to realize real-time transmission of the audio and video information, graphics information and text chat information. On this basis, the system has realized the sharing whiteboard sharing graphics, text chat and audio and video chat. According to the demand of the project, the system encrypt the information in the process of data transmissions, which enhance the security of WebRTC when connection is establishing. After system testing, the system can run on the browser of PC end and intelligent mobile terminal to achieve voice and video calls, drawing and text communication. This system provides an effective solution for real-time meeting and employees training in enterprises.
