Abstract: Conflict resolution during data synchronization may be improved by sending an update version along with a synchronization request to a user having previously received a different update version from the user.

Abstract: Dynamic switching between mirrored and non-mirrored implementations is provided by formatting a system to operate in a simulated mirrored mode. A null location is used as a placeholder for a storage location that can be subsequently added. The null location is replaced in whole or in part by the storage location when actual mirrored node is desired, thereby making the switch to actual mirrored mode appear dynamic and transparent to a user. A first location is designated as a first part of a mirror, and the null location is designated to simulate a second part of the mirror. Data and/or operating systems may be mirrored.

Abstract: A method for detecting a presence of a device on a network, and determining if an address exists for the device within the network. If it is determined that the address exists, recall the existing address of the device. Additionally, if it is determined an address does not exist for the device, generate and store an address for the device.
