摘要
下一代网络是基于分组交换的网络。SIGTRAN作为下一代网络中专门用于传输信令的传输层协议,对信令传输的可靠性、时延等问题起着至关重要的作用。QoS问题是IP网络中的关键问题,也是下一代网络中需要重点考虑的问题。SIGTRAN协议在设计的时候就考虑到了许多保证QoS的措施,从而保证了下一代网络中信令消息的传输性能。文中简要介绍了SIGTRAN协议的体系结构,给出了SIGTRAN中的QoS定义,分析了SIGTRAN中的各种QoS保障措施,最后对这些QoS保障措施进行了总结。
Next generation network is based on packet switch. Transport layer protocol of SIGTRAN that is special for the signal transmission plays a very important role in keeping the reliability of the signal transmission. QoS is the key issue in IP network, and need be considered seriously in next generation network. During the design of SIGTRAN, control mechanisms of QoS have been considered. Accordingly it ensues the transmission performance of signal information. This paper introduces the system of SIGTRAN protocol and the definition of QoS in SIGTRAN. Control mechanisms of QoS are analysed in detail and summarized in the end.
