软交换信令网关中传输协议的探讨

Discussion of Transport Protocols in Signaling Gateway of Softswitch

信令网关是软交换系统的重要组成部分,它用于解决现有No.7信令网与IP网之间的无缝融合问题。本文首先介绍了信令网关协议栈的参考模型,以及IETF建议的流控制传输协议的特点,最后总结了SCTP协议优于TCP协议的一些特性。

As an important department of softswitch system, the signaling gateway （SG） is used to resolve the seamless fusion of No.7 and IP. This paper firstly introduces the reference model of SG protocol stack and the SCTP feature of IETF.Lastly it generalizes the excellent performance that SCTP than TCP.
