摘要:
A method, apparatus and system for Ethernet Ring Protection (ERP) are disclosed. The system includes: a node which detects a link fault blocks the port connected with the faulty link after the link on the ring is faulty, and sends a fault alarm message to adjacent nodes; and the adjacent nodes judge whether the state of the node changes from the normal state to the faulty state according to the received fault alarm message, and clear the forwarding table of the node if such is the case.
