Abstract
A variety of techniques are disclosed for efficient liveness monitoring in a reliable publish/subscribe multicast system having at least one broker and at least one subscriber, by: at the broker, sending (310) a status request message to the subscriber, and at the subscriber, sending (350) a status response message to the broker to indicate liveness. Status responses by subscribers may be suppressed when at least a chosen minimum number (>=1) of subscribers send a response. This suppression (320-340) uses a system of 'response claim' messages and random back-off timers. These provide the advantage that the efficiency of network usage is improved by reducing the number of unwanted packets that are sent.
