Protection switching methods and systems for electronic devices

摘要

Per-interface electronic device protection switching systems and methods are disclosed. An electronic device and each communication line interface provided in the device are monitored, and device information and interface information are generated. The device and interface information is periodically sent to a mate electronic device in a protection group to which the electronic device belongs. Mate device information and mate interface information are also received by the device from the mate device. Activity states of each device interface are controlled based on at least one of the device information, the interface information, the mate device information, and the mate interface information.
