Abstract
The disclosure provides for a reactive cache coherence protocol that has efficiencies over proactive approaches. Rather than proactively performing remediation when a data item is invalidated, a destination endpoint checks cache coherence upon receiving an indication of a cache hit, and based at least on detecting a lack of coherence, performs a reactive remediation process. For example, the incoherence may be fixed by replacing, as a cached data item, a data block indicated by the cache hit with a replacement data block that triggered the cache hit.
