Abstract

This paper defines and outlines and proposes a heuristic method to detect unavailability on a practical service created on the Internet. It uses a token that is passed between all the nodes. The algorithm is under trial in a set of servers spanning over multiple administrative domains. This paper confirms that using a simple token passed through the contributing applications servers, is able to detect unavailability without intruding or changing the service that one wants to monitor.
