【摘要】：WebRTC (Web Real-Time Communications)技术提供以浏览器为通信媒介的音视频实时通信功能,并且无需依赖桌面客户端。基于WebRTC的通信模式越来越卞富多样,作为一个处在发展阶段的通信系统,需要保证系统的架构具有高内聚低耦合的特性,需要增强系统的可扩展性、可重用性。本文研究的通信模块作为WebRTC系统的核心基础模块,为WebRTC系统提供最核心的实时通信功能和即时通信功能,为今后WebRTC系统的扩展和开发提供底层技术支撑。本文针对通信模块中的实时通信业务开发架构进行了研究与分析,设计并实现了选定的优化架构方案,该方案将通信模块划分为三个层次:应用层、会话层、连接层。各个层次各司其职,下一层为上一层提供服务,增加了系统的灵活性,增强了通信模块的可扩展性、可重用性,同时为二次开发提供了开发接口,为丰富多样的通信方式的开发提供了便捷。本文设计并实现了 WebRTC系统中的即时通信子模块,为用户提供基于浏览器的即时通信业务。即时通信功能的实现采用环信IM平台的服务器来作为即时通信服务器,环信IM平台可以为用户提供高可靠、高效率的即时通信功能。即时通信客户端的开发过程中,基于实时通信的开发架构思想,分为三个层次来依次扩展实现,即通过对应用层、会话层、连接层做扩展开发,从而实现即时通信基本功能、好友相关功能、群组相关功能。最后,本文对WebRTC系统中的通信模块进行了功能测试和性能测试,测试结果表明WebRTC系统中通信模块的实时通信业务和即时通信业务都能够可靠运行。
[Abstract]:WebRTC / Web Real-Time Communications (WebRTC) technology provides real-time audio and video communication with browser as communication medium, and does not depend on desktop clients. Bian Fu communication mode based on WebRTC is becoming more and more diverse. As a communication system in the development stage, it is necessary to ensure that the architecture of the system has the characteristics of high cohesion and low coupling, and to enhance the extensibility and reusability of the system. As the core basic module of WebRTC system, the communication module studied in this paper provides the most core real-time communication function and instant communication function for WebRTC system, and provides the underlying technical support for the extension and development of WebRTC system in the future. In this paper, the architecture of real-time communication service development in communication module is studied and analyzed, and the optimized architecture is designed and implemented. The scheme divides the communication module into three levels: application layer, session layer and connection layer. The next layer provides the service for the upper layer, increases the flexibility of the system, enhances the extensibility and reusability of the communication module, and provides the development interface for the secondary development. It provides convenience for the development of rich and diverse communication modes. In this paper, we design and implement the instant communication submodule in WebRTC system, which provides users with instant messaging services based on browser. The instant messaging function is realized by using the server of the Ring IM platform as the instant messaging server. The ring IM platform can provide users with high reliability and high efficiency instant messaging function. In the development process of instant messaging client, based on the development architecture of real-time communication, it is divided into three levels to expand the implementation in turn, that is, by developing the application layer, session layer and connection layer, so as to realize the basic function of instant communication. Friends related function, group related function. Finally, the function and performance of the communication module in the WebRTC system are tested. The test results show that the real-time communication service and the instant messaging service of the communication module in the WebRTC system can run reliably.
