APPLICATION CACHE REPLICATION TO SECONDARY APPLICATION(S)

摘要

Replicating a primary application cache that serves a primary application on one network node into a secondary application cache that serves a secondary application on a second network node. Cache portions that are within the primary application cache are identified, and then identifiers (but not the cache portions) are transferred to the second network node. Once these identifiers are received, the cache portions that they identify may then be retrieved into the secondary application caches. This process may be repeatedly performed such that the secondary application cache moves towards the same state as the primary application cache though the state of the primary application cache also changes as the primary application operates by receiving read and write requests.

1. In a system in which there is a primary application that operates at least in part on a first network node and that includes a primary application cache on the first network node, the primary application having an associated secondary application that operates at least in part on a second network node and that includes a secondary application cache on the second network node, a method for at least partially replicating the primary application cache in the secondary application cache, the method comprising:
an act of identifying at least some cache portions identifiers that are within the primary application cache; an act of transferring the identified cache portion identifiers to the second network node; and an act of retrieving into the secondary application cache at least one of the cache portions identified in the transferred cache portion identifiers.
