Abstract
A method, a system and a storage medium for network failure protection belonging to the field of network technologies. The method comprises: allocating, for each forwarding link of the ring topology, a protection ring bit position opposite to the direction of a working path; newly adding BRFT for storing adjacent forwarding table entries related to forwarding along the direction of the protection ring bit position; and when a BIER message is forwarded along the working path, if a BFR detects that the downstream adjacency fails, searching for entry content of the BTAFT, finding the correlation between the link bit position of the fault forwarding link and the protection ring bit position, and forwarding, on the basis of entry content of the BRFT, the BIER message to the opposite end fault point of the opposite end along the direction of the protection ring bit position.
