A Fault Tolerant Token Based Atomic Broadcast Algorithm Relying On Responsive Property

Mr. Neelamani Samal, Mr. Debasis Gountia, Mrs. Madhusmita Sahu

In the Distributed Environment where shared resources are involved, we have basically two types of
mechanism to allocate the shared resources: either by passing tokens or by having Request and Reply
Messages. In the shared environment, a processor might fail (i.e. may crash which may lead to failure). This paper
proposes a fault tolerant token based atomic broadcast algorithm which does rely on unreliable failure detectors.
It combines the failure detector and a token based mechanism, satisfying responsiveness property. The mechanism can
tolerate processor level faults as compared to the existing system level failure, because the proposed system is relying
on the unreliable failure detector and also rely on the responsive property.
