Digital simulation for the integrated imformation transmission network of a certain power company is performed, the QoS under three configuration schemes, i.e., without QoS configuraiton, with simple differnece service configuraiton and with MPLS network configuration, are compared. Comparison resutls show that the configuration scheme of MPLS network can implement the load balance among link circuits and possesses fault self-recovery mechanism, so the failure elements can be quickly detected and the switching over of data flow among label switched paths can be realized. The fault recovery time is within miliseconds, therefore the QoS of power system realtime information can be ensured effectively and the QoS of various non-realtime information can be considered as well.
