ABSTRACT:
Disclosed is a method for handling fault between an Egress LSR and an Egress data device connected with it, including the following steps: an Egress Label Switching Router (LSR) transmitting fault information to an Ingress LSR after detecting a fault of an Egress Work link connected with it; the Ingress LSR adjusting a service flow transmission according to the received fault information. When there exists an Egress Protect link in the network, the present invention can transmit the service flow through the Egress Protect link, thus it is guaranteed that the service flow can be transmitted to the Egress data device; and the service flow is not transmitted when there is no Egress Protect link in the network, thus the waste of network resources is avoided.
