Abstract
A method may receive, at a first node, a first message with a first message data structure from a second node. The first message data structure may include a counter for each resource of a plurality of resources that is indicative of a most current age of a master copy of the resource known by the second node. The first node may include a current data structure with a counter for each resource that is indicative of a most current age of the master copy of the resource known by the first node. The method may determine whether at least one counter in the current data structure is older than the corresponding counter in the message data structure. The method may update the counter that is older, e.g., to learn the most current age of the master copy of the resource known by the second node, based on the determination.
