Abstract: A ProbeSystem for one or more Replicas is disclosed. For each replica, the Probe System includes a ProbeHead that updates a Head field in a Target Record pertaining to the Replica and a ProbeEcho that updates an Echo field in the TargetRecord. The Head field includes a time stamp and an epoch value. The Echo field includes a latency value and an epoch value. The fields are such that, during reporting, the ProbeHead can analyze the TargetRecord for the replica to determine the latency between one or more paths between the Replica and other Replicas. The ProbeSystem has a peer-to-peer shared nothing architecture and applies to a large class of high-replica, distributed and high-scale cloud storage systems and services.

Abstract translation: 披露了一个或多个副本的ProbeSystem。 对于每个副本，Probe系统包括一个ProbeHead，用于更新与Replica有关的目标记录中的Head字段和更新TargetRecord中的Echo字段的ProbeEcho。 头字段包含时间戳和时期值。 回波场包括延迟值和时期值。 这些字段使得在报告期间，ProbeHead可以分析复制副本的TargetRecord，以确定副本和其他副本之间的一个或多个路径之间的延迟。 ProbeSystem具有点对点的无共享架构，适用于大型高复本，分布式和大规模云存储系统和服务。
