摘要
探讨了软交换中多协议导致的复杂性,研究了协议组内及协议组间的协议关系处理,设计了通用PDU,考虑了软交换的可扩展性,可用性方面的问题.借鉴SIP-T协议的机制,在通用PDU中广泛采用信息翻译和信息封装共存的方式,实现了系统的高效性和信息的完整性.揭示了协议关系分类和协议分组对软交换设计的必要性和有效性.最后利用UML对软交换进行了设计.
This paper discussed the complexity of softswitch because of its multi-protocol property. How to deal with the protocol relationships in each protocol group or between different protocol groups was studied. Generic PDU was designed. The extensibility and availability of softswitch were also under consideration. Based on a mechanism of SIP-T, the information translation mode and information encapsulation mode coexisted widely in the generic PDU, by which the high efficiency of system and integrality of information were ensured. The necessity and validity of protocol relationship and protocol grouping were proved. UML was used to design the softswitch.
