摘要: 针对互联网存在的实时服务集成问题,提出基于会话初始化协议(SIP)的异构实时服务集成平台,利用SIP URI对实时服务进行编址,并将其封装为接口统一的原子服务,采用服务注册和应用层路由的方式实现原子服务的调用,以P2P方式进行实时信息传输,确保系统的可扩展性,通过实现原型系统——公众交通出行服务系统,验证了该平台的可行性。

关键词: 实时, 服务集成, 服务调用, 会话初始化协议

Abstract: Aiming at the problems of integration of real-time services in Internet, an heterogeneous real-time services integrated platform based on Session Initiation Protocol(SIP) is proposed, in which, real-time services are assigned SIP URI address and encapsulated into atomic services with uniform interface. Atomic services are invocated by service-register and application-layer-routing mechanisms. Considering scalability of the platform, real-time information is transferred by P2P method. By implementing the prototype system, the public traffic guide system, the feasibility of this platform is proved.

Key words: real-time, service integration, service invocation, Session Initiation Protocol(SIP)
