摘　　要：为了选择适合于容灾系统的传输技术,需要对容灾系统的传输时延进行研究。文章对比分析了基于SAN技术的容灾系统中的几种主流互联技术,以及选用波分技术的优势;采用理论分析和搭建实验平台验证的方法,建立光纤和波分系统的综合传输时延的模型,证明了模型的正确性,进一步得出了影响容灾系统传输时延的主要因素是光纤传输、传输器件时延的结论。in order to select an appropriate transmission technology applicable to the disaster recovery system, there is a need to study the transmission delay in the disaster recovery system. Several mainstream SAN-based interconnection technologies used in disaster recovery systems are compared, and the advantages of choosing tile WDM technology are described. Theoretical analysis and experimental platform authentication methods are used to build an integrated fiber and WDM transmission delay model, which proves the correctness of the model. Furthermore, a conclusion that the major factors impacting the transmission delay in the disaster recovery system are the optical fiber transmission and the transmission device delay is drawn.
