摘要：Each network of data processing systems within a system of networks is assigned a unique network identifier when connected to the system. Each data processing system within a given network is assigned a unique host system identifier when the data processing system is added to the network. When a new object is added to a given data processing system, a unique object identifier is constructed with three fields, including a high order field containing the network identifier for the network in which the object is being added, a next order field containing a host system identifier for the data processing system to which the object is being added, and an object identifier unique for all objects within the host data processing system. The combination of the three identifiers results in a single, unique object identifier which is unique for all objects across the system of networks and data processing systems. The host data processing system need not be connected to any other data processing system or network at the time the object is added to guarantee that the object identifier is unique across the entire system of networks. Therefore, the object may be added to a database of objects distributed among a plurality of data processing systems and accessed by an application communicating, when bandwidth is available, with other data processing systems over the Internet.
