SSCOP信令传输时延分析与检测

Analysis and Detection of SSCOP Signaling Link Transmission Delay

SSCOP协议是ATM宽带网络信令系统数据链路层的一部分,SSCOP信令链路为ATM网络元素之间提供可靠的信令信息传输。信令链路传输时延是ATM网络传输质量的一个重要参数,SSCOP协议的很多重要参数的取值都依赖于传输时延的大小。介绍一种SSCOP信令链路传输时延的检测方法,通过构造一种特殊的SSCOP报文来测试信令网络的传输质量,并计算信令报文的传输时延。对提高ATM信令系统的网络质量和优化SSCOP协议参数具有一定的现实意义。

SSCOP protocol is part of data link layer in signaling ATM broadband networks,which provides reliable transmission of signaling information between the ATM network elements.Signaling link transmission delay is an important parameter of ATM network,and many values of SSCOP protocol parameters are dependent on the delay size.In order to optimize SSCOP protocol parameter and improve the quality of ATM signaling networks,this paper proposes a detection and calculation method for SSCOP signaling link transmission delay,which is achieved by sending a special SSCOP message to detect the transmission quality on both sides and to calculate the transmission delay.
