<p>A method for the Ethernet Private Line (EPL) service maintenance in the Automatic Switched Optical Network (ASON) is provided by the present invention, which includes the following steps: the head node receives or detects that the connection information of the head node and the end node in the EPL service is inconsistent; the head node and the end node perform rollback operation, so that the connection information of the head node and the end node can return to a consistent state. A system for the EPL service maintenance in the ASON network is also provided by the present invention, which includes a head node detection module, a head node rollback module and an end node rollback module. The present invention solves the problem that the connection information of the head node and the end node is inconsistent in the EPL service, and ensures the normal operation of the EPL service.</p> |
