SCTP协议特性与应用方式的研究

Research on protocol feature and applicability of SCTP

通过与TCP的对比,对SCTP的多宿、多流和面向消息等主要的协议特性和两个非常重要的扩展特性,部分可靠性与动态地址重配置进行了分析。对SCTP在信令传输之外其他领域中的可能的应用方式进行了讨论。提出了利用SCTP的特性构建基于移动通信网络的远程实时系统的设想;对使用SCTP重新实现一些传统的网络服务的可应用性进行了分析;讨论了移动SCTP作为一种地址切换管理机制对Internet移动性的支持。

By comparing SCTP with TCP, the main features of SCTP such as multi-homing, multistreaming, message-oriented and two important protocol extensions, partial reliability and dynamic address reconfignration, are analyzed. Some possible applications of SCTP other than signal transmission are discussed： constructing remote real time system over public mobile communication network with SCTP, implementing some traditional applications with SCTP to improve service performance and using mobile SCTP as a soft handover management scheme to support Internet mobility.
