“…Overall, AllConcur+ achieves comparable throughput to AllGather, a non-fault-tolerant distributed agreement algorithm, and, especially at scale, significantly higher throughput and lower latency than other fault-tolerant algorithms, such as AllConcur [53], LCR [26] and Libpaxos [57]. Moreover, our evaluation of various failure scenarios shows that AllConcur+'s expected performance is robust with regard to occasional failures.…”

“…When no failures occur, AllConcur+ achieves between 79% and 100% of the throughput of AllGather, a non-fault-tolerant distributed agreement algorithm. When comparing with other fault-tolerant algorithms-AllConcur [53], LCR [26] and Libpaxos [57]-AllConcur+ outperforms them both in terms of throughput and latency: It achieves up to 6.5× higher throughput and up to 3.5× lower latency than AllConcur; up to 6.3× higher throughput and up to 3.2× lower latency than LCR; and up to 318× higher throughput and up to 158× lower latency than Libpaxos. Moreover, our evaluation of failure scenarios shows that AllConcur+'s expected performance is robust with regard to occasional failures.…”

Many distributed systems work on a common shared state; in such systems, distributed agreement is necessary for consistency. With an increasing number of servers, these systems become more susceptible to single-server failures, increasing the relevance of fault-tolerance. Atomic broadcast enables fault-tolerant distributed agreement, yet it is costly to solve. Most practical algorithms entail linear work per broadcast message. AllConcur-a leaderless approach-reduces the work, by connecting the servers via a sparse resilient overlay network; yet, this resiliency entails redundancy, limiting the reduction of work. In this paper, we propose AllConcur+, an atomic broadcast algorithm that lifts this limitation: During intervals with no failures, it achieves minimal work by using a redundancy-free overlay network. When failures do occur, it automatically recovers by switching to a resilient overlay network. In our performance evaluation of non-failure scenarios, AllConcur+ achieves comparable throughput to AllGather-a non-fault-tolerant distributed agreement algorithm-and outperforms AllConcur, LCR and Libpaxos both in terms of throughput and latency. Furthermore, our evaluation of failure scenarios shows that AllConcur+'s expected performance is robust with regard to occasional failures. Thus, for realistic use cases, leveraging redundancy-free distributed agreement during intervals with no failures improves performance significantly.

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 17× 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. *
