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. %G English %2 https://inria.hal.science/hal-01056495/document %2 https://inria.hal.science/hal-01056495/file/019_Microsoft_Word_EUNICE_2010finalupdate_28Final_Version_29_v1.pdf %L hal-01056495 %U https://inria.hal.science/hal-01056495 %~ IFIP-LNCS %~ IFIP %~ IFIP-LNCS-6164 %~ IFIP-TC %~ IFIP-TC6 %~ IFIP-WG6-6 %~ IFIP-EUNICE %~ IFIP-2010
