Using Tailored Failure Suspectors to Support Distributed Cooperative Applications.
François J. N. Cosquer, Luı́s Rodrigues, Paulo Verı́ssimo · 1995
This paper presents an approach to effectively support cooperative applications using tailored failure suspectors. Using a group communication subsystem, it is shown how failure suspectors can be configured to model the requirements/semantics of cooperative applications thus avoiding ad-hoc system decisions. This approach is highly relevant in the context of large scale distributed systems like the Internet, where communication high variance and unpredictable delays increase the probability of incorrect failure detection. Applications are presented illustrating how failure suspectors are configured and possibly combined with new feedback techniques in order to implement more powerful cooperative environments.
