| Abstract: | 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. |
