Projects in Atomic Commit Protocols

Principal Investigator: P.K. Chrysanthis

The Implicit-Yes Vote protocol is an atomic commit protocol that has been proposed for the future gigabit-networked distributed databases employing strict two-phase locking for concurrency control. By exploiting the network bandwith, IYV eliminates the first phase of the two-phase commit protocol, hence reducing the time required to commit a distributed transaction during normal processing, at the expense of independent recovery of failed participant sites.
