SYSTEM AND METHOD FOR NETWORK RECOVERY FROM MULTIPLE LINK FAILURES

摘要

Methods and systems for fast and reliable network recovery from multiple link failures. In accordance with one example of the method, a master node receives a request from a transit node having a blocked port to open the blocked port for data forwarding, wherein the blocked port is associated with a restored link. The master node starts a health-check timer and transmits a health-check message on its primary port to determine that all failed links of the network are restored. Upon determining that the health-check message is received at its secondary port, the master node transmits a message to each transit node indicating that all failed links are restored. Upon determining that the health-check message is not received at its secondary port before the health-check timer lapsed, the master node transmits a message to the transit node to open the blocked port associated with the restored link for data forwarding.
