Abstract: A Replication and Synchronization Engine (RSE) provides a user of a mobile computer with a consistent namespace of resources available to a network despite the connection status of the computer. The specifications (names) of the resources as viewed by the user when the computer is connected to the network are identical to the names as viewed by the user when the computer is disconnected from the network. RSE provides such a consistent namespace by maintaining complete, local replicas of a user-selected subset of these resources at the mobile computer, along with local "name-only" representations of the remaining resources. The resources maintained by RSE may include any network resource, such as a server, volume, directory, file, printer queue and other object, that the mobile computer can access.

Abstract: A private network is built by first allowing a pre-determined number of client systems to connect directly to a server system. After this occurs, additional client systems requesting connection are furnished with the addresses of client systems already connected within the private network. Each of the additional client systems then makes connections with a multiple number of client systems to receive information from the server system. Each of these client systems subsequently accepts connections from up to a second pre-determined number of client systems to which it transmits information received from the server system.
