Abstract
A system an method for efficiently providing access by a large number of clients to objects located at a large number of information servers. A non-bottleneck solution is provided to sharing load among servers by migrating or replicating objects over from highly loaded servers to less highly loaded servers. Objects that experience low loading are deleted to make room for more highly used objects and to permit make space for new objects. A naming service is provided to provide rapid access to a replica of a requested objects, while avoiding directing access requests to servers from which replicas of requested objects have been deleted. Hierarchical ordering of replication and naming functions permits a variety of particular access methods to be realized.
