A design and implementation of cluster heartbeat network for efficient fault detection

To achieve fault tolerance in a server cluster,fault detection capability is a primary prerequisite. efficient fault detection is prompt,correct and complete. this paper revisited the technique called reactive failure detection (rfd) that dynamically predicts a heartbeat delay from a cluster node. we also identified the requirements to deploy rfd in actual servers. a new cluster heartbeat network with concurrency is proposed to use push and pull interaction during live monitoring and determining node's status. the prototype of the new model is tested on a platform running multiple independent web applications and analyzed for its implementation and design correctness.
