Abstract

A publish/subscribe interface is used to enable a non-publish/subscribe first system (such as an IP network device) to obtain status information about a publish/subscribe device that cannot be pinged by the first system. The first system sends a status request to a domain name server. The status request includes a domain name for the publish/subscribe device. Topic space maintained by a message broker in the publish/subscribe system includes status topics associated with publish/subscribe devices. The status topics contents reflect the current availability of the associated publish/subscribe device.
