标题： On Orchestrating Parallel Broadcasts for Distributed Ledgers

摘要： 本文介绍了并发展了“票务”概念，通过该概念，分布式系统中的节点协调原子广播。 本文研究了不同的票务制度，这些制度允许并行性，同时防止慢速节点阻碍整体进展。 它引入了一种混合方案，结合了受控和非受控票务制度，在适应性和弹性之间取得平衡。 性能评估展示了受控和非受控票务制度在静态和动态场景下如何提高异构资源系统的吞吐量，其中受控票务制度表现更好，因为它适应性更强。 最后，它展示了使用混合票务制度如何能够同时享受受控制度的适应性和非受控制度的活跃性保证。 显示英文摘要

摘要： This paper introduces and develops the concept of ``ticketing'', through which atomic broadcasts are orchestrated by nodes in a distributed system. The paper studies different ticketing regimes that allow parallelism, yet prevent slow nodes from hampering overall progress. It introduces a hybrid scheme which combines managed and unmanaged ticketing regimes, striking a balance between adaptivity and resilience. The performance evaluation demonstrates how managed and unmanaged ticketing regimes benefit throughput in systems with heterogeneous resources both in static and dynamic scenarios, with the managed ticketing regime performing better among the two as it adapts better. Finally, it demonstrates how using the hybrid ticketing regime performance can enjoy both the adaptivity of the managed regime and the liveness guarantees of the unmanaged regime.
