Abstract

A method for service protection and an access device are provided. The method includes: the continuity fault detection of service level is performed at a service path between an access node and aggregation node, and a maintenance end point for performing the continuity fault detection of service level is configured at the access node and aggregation node; when the access node detects the continuity fault detection of service level, a standby physical link of a main physical link is activated, so that the standby Label Switching Path (LSP) and standby pseudo wire of the standby physical link are available; the service with fault is switched from the main pseudo wire carrying the service to the standby pseudo wire, wherein the main pseudo wire is the pseudo wire carried by the main LSP at the main physical link, and the standby pseudo wire is the pseudo wire carried by the standby LSP at the standby physical link. By using the method, the service protection process is simplified, and the protection methods of various services such as unicast, multicast and so on are integrated.
