Abstract
The emergency alert service responds to receipt of emergency alert messages by filtering, formatting and routing emergency alert information to a variety of different networked appliances and also to remote devices. In this way, a consistent warning message is disseminated simultaneously over many different warning systems, thus increasing warning effectiveness while simplifying the warning task. The system thus provides a common alerting protocol that is simple but quite robust and capable of exchanging all-hazard emergency alerts and public warnings over all kinds of networks.
