Mechanisms for failure detection and mitigation in a gateway device

A method is capable of detecting and mitigating failure conditions associated with gateway devices. According to an exemplary embodiment, the method includes receiving a first announcement regarding service associated with operation of a gateway device (440), determining a classification of the first announcement (510), initializing a timing interval based on the classification of the first announcement (520), and providing an error message if a second announcement of a same classification as the first announcement is not received before the timing interval expires (530). The gateway device isconsidered to be operating properly if the second announcement of the same classification as the first announcement is received before the timing interval expires.
