Abstract: Based on the session initiation protocol (SIP), this paper analyzes some kinds of network structures applied in system, and proposes a mixed network structure for the multi-domain and multi-transmission-medium E-education system. It discusses the principles of such kind of system in detail, and depicts the function of each unit and the method to achieve it, which provides an idea to develop the E-education system.

Key words: Session initiation protocol (SIP), E-education system, Hybrid network

摘要： 以SIP协议为基础，分析了在远程教育应用中的多种网络结构，提出了一种适用于多区域、多种传输媒介的混合式网络结构。论述了基于混合式网络结构的SIP远程教育系统的工作原理，并对各系统组件的功能及具体实现方法进行了全面阐述。为远程教育系统的实现提供了新的思路和方法。
