Repairman Models for Replicated Data Management: A Case Study

  title={Repairman Models for Replicated Data Management: A Case Study},
  author={Ing-Ray Chen and Ding-Chau Wang},
Pessimistic control algorithms for replicated data permit only one partition to perform update operations at any time so as to ensure mutual exclusion of the replicated da ta object. Existing availability modeling and analyses of pessimistic control algorithms are constrained to either site-failure or link-failure only models, but not both, because of the large state space which needs to be considered. Moreover, the assumption of having an independent repairman for each link and each site has… CONTINUE READING
