Query: AllConcur: Leaderless Concurrent Atomic Broadcast (Extended Version)   Many distributed systems require coordination between the components
involved. With the steady growth of such systems, the probability of failures
increases, which necessitates scalable fault-tolerant agreement protocols. The
most common practical agreement protocol, for such scenarios, is leader-based
atomic broadcast. In this work, we propose AllConcur, a distributed system that
provides agreement through a leaderless concurrent atomic broadcast algorithm,
thus, not suffering from the bottleneck of a central coordinator. In AllConcur,
all components exchange messages concurrently through a logical overlay network
that employs early termination to minimize the agreement latency. Our
implementation of AllConcur supports standard sockets-based TCP as well as
high-performance InfiniBand Verbs communications. AllConcur can handle up to
135 million requests per second and achieves 17x higher throughput than today's
standard leader-based protocols, such as Libpaxos. Thus, AllConcur is highly
competitive with regard to existing solutions and, due to its decentralized
approach, enables hitherto unattainable system designs in a variety of fields.
