High performance state-machine replication

Computer systems are usually made fault tolerant through replication. By replicating a service on multiple servers we make sure that if some replicas fail, the service can still be performed by the operational nodes. However once a service is replicated, ensuring consistency among all the copies is not easy. Conflicting requests submitted simultaneously to different nodes can lead to inconsistent states in the replicas and therefore meaningless replies to clients. My research addresses the design and implementation of one of the pillars of replication, atomic broadcast. The goal is to propose solutions for high performance atomic broadcast algorithms that are capable of addressing consistency with low latency and high throughput.
