The lack of accuracy in such systems comes from the use of timeouts to suspect the failure of a site, a technique that may trigger false suspicions. H. Orman, E. Menze, S. O'Malley, and L. Peterson. A fast and general implementation of Mach IPC in a network . In 3rd Usenix Mach Conf. The lack of accuracy in such systems comes from the use of timeouts to suspect the failure of a site, a technique that may trigger false suspicions.
Live detection is based on lack of response from a site, i.e. timeouts.
Accurate detection, on the other hand, cannot be based on communication since the network is assumed to be asynchronous. A fast and general implementation of Mach IPC in a network . The socket based implementation uses the socket interface provided by the Lites Unix server. We have yet to explore alternatives for cross machine communication. Interoperability SR programs running on top of Mach will not exist in isolation, they will need to interact with non SR programs.
