Efficient Transparent Optimistic Rollback Recovery for Distributed Application Programs
Existing rollback-recovery methods using consistent checkpointing may cause high overhead for applications that frequently send output to the “outside world,” since a new consistent checkpoint must be written before the output can be committed, whereas existing methods using optimistic message logging may cause large delays in committing output, since processes may buffer received messages arbi...
متن کاملOptimistic Fair Exchange with Transparent Signature Recovery
We propose a new protocol allowing the exchange of an item against a signature while assuring fairness. The proposed protocol, based on the Girault-Poupard-Stern signature scheme (a variation of the Schnorr scheme), assumes the existence of a trusted third party that, except in the setup phase, is involved in the protocol only when one of the parties does not follow the designated protocol or s...
متن کاملAsynchronous Optimistic Rollback Recovery Using Secure Distributed Time
In an asynchronous distributed computation, processes may fail and restart from saved state. A protocol for optimistic rollback recovery must recover the system when other processes may depend on lost states at failed processes. Previous work has used forms of partial order clocks to track potential causality. Our research addresses two crucial shortcomings: the rollback problem also involves t...
متن کاملA Fast Rollback-Recovery Scheme based on Optimistic Message Logging
This paper presents an eecient rollback recovery scheme based on the optimistic message logging. To speed up the recovery process, the rollback point of the failed process is broadcast and other processes asynchronously make the rollback decision based on the vector time. Asynchronous recovery process usually causes two possible problems: One is the message delivered from an invalid state inter...
متن کاملImplementation and Performance of Transparent Rollback-recovery in Manetho
We describe the implementation and performance of rollback-recovery in Manetho. During failure-free operation, Manetho maintains an antecedence graph which records the \happened before" relation between certain events in the distributed computation. The antecedence graph is used in combination with checkpointing and volatile sender-based message logging to simultaneously achieve low failure-fre...
