Cluster Arbitration via Preemption Representatives

The patent merges multiple independent arbitration mechanisms into a unified arbitration system. A shared arbitration device is introduced that coordinates fault handling across all clusters, ensuring consistent arbitration results. The arbitration device receives fault information from different clusters and coordinates their arbitration processes, transforming independent operations into a coordinated unified action that maintains service continuity.

The patent introduces an arbitration device as an intermediary between clusters. This mediator receives fault notifications from various clusters, manages the arbitration process centrally, and coordinates the survival decisions across clusters. The intermediary ensures that arbitration results are consistent and prevents service interruptions by harmonizing the autonomous fault handling of different clusters.

The patent segments the arbitration system into two distinct parts: a centralized arbitration device that manages coordination and consistency, and local cluster components that execute specific arbitration tasks. This segmentation allows the unified arbitration mechanism to maintain consistency while keeping the complexity localized and manageable. The arbitration device handles the complex coordination logic, while clusters follow standardized procedures.

The arbitration device is designed as a universal component that handles arbitration for multiple clusters simultaneously. It performs multiple functions including receiving fault information from different clusters, managing arbitration processes, and coordinating survival decisions. This multi-functionality reduces overall system complexity by consolidating arbitration capabilities into a single versatile device rather than requiring separate mechanisms for each cluster.

The patent implements a feedback mechanism where the arbitration device receives fault information from clusters across different data centers and uses this information to coordinate arbitration decisions. The arbitration device processes feedback from various clusters and adjusts its coordination to ensure consistent arbitration results. This feedback loop ensures that service availability in one data center does not compromise service access consistency in other data centers.

The patent creates equipotentiality in the arbitration process across all data centers by introducing a centralized arbitration device that applies the same arbitration logic uniformly. This ensures that all clusters, regardless of which data center they belong to, are treated equally during fault conditions. The arbitration device balances the arbitration process, preventing situations where one data center's cluster survival creates inconsistency in other data centers.
