Abstract

An apparatus for distributing software implements directory services of a network to provide data for controlling a distribution of software. A software object may be any electronic representation of data of any type, from a single byte, to a complex application, or the like. A directory services computer, responsible for maintaining a data store of inter-related logical entities may store a distribution object containing all distribution information associated with a distribution. Distribution information may include a listing of targets, actual entities represented as logical entities in the data store, which are to receive a distribution of a software object. The directory services computer provides instantiations of various portions or an entire data store to be read by various nodes or computers throughout a network or internetwork. Accordingly, an individual computer, such as an individual client or workstation may read information in a distribution object, identified itself as a target of a distribution, and pull the designated software object, completing the distribution to itself. Distribution may also be effected by a workstation from a remote source node to a remote destination node. Authorizations, timing, targets, and software objects, may all be identified in a distribution object.

Claims

1. An apparatus for distributing software, the apparatus comprising:

a network interconnecting a plurality of nodes including a source node storing software;

a directory services node storing a network directory services system comprising directory services objects having attributes and managed by a directory services executable, each directory services object corresponding to an entity and operably related in a hierarchical tree to others of the directory services objects, the hierarchical tree reflecting the relationships between the entities;

the directory services node being operably connected to the network and programmed to maintain a distribution object of the directory services objects, the distribution object corresponding to the software and containing attributes comprising distribution-controlling data for controlling distribution of the software, the software being independent from the directory services executable;

a workstation node operably connected to the directory services node to retrieve the distribution-controlling data from the distribution object of the directory services node and programmed to distribute the software in accordance with the distribution-controlling data.

2. The apparatus of claim 1, wherein the software is embodied in a software object, and the workstation node is programmed to distribute the software object to the workstation node.

3. The apparatus of claim 2, wherein the distribution-controlling data further comprises a set of distribution parameters, for controlling the distribution, and an identification corresponding to the software object.

4. The apparatus of claim 3, wherein the distribution object is recognizable by the workstation node, and contains the distribution parameters.

5. The apparatus of claim 4, wherein the distribution object further comprises a distribution list identifying targets, selectable from the logical entities, the targets corresponding to actual entities to receive the distribution of the software object.

6. The apparatus of claim 5 wherein:

the logical entities are interrelated in a hierarchy comprising a plurality of levels, each logical entity pertaining to a corresponding level; and

the distribution list contains targets selected from more than one of the levels.

7. The apparatus of claim 4, wherein the distribution parameters include scheduling data for controlling scheduling of the distribution of the software object.

8. The apparatus of claim 7, wherein the scheduling data is effective to schedule a parallel distribution of the software object to a plurality of workstation nodes.

9. An article of manufacture comprising at least one memory device containing data structures comprising:

a directory services system comprising directory services objects having attributes and managed by a directory services executable, each directory services object corresponding to an entity and operably related in a hierarchical tree to others of the directory services objects, the hierarchical tree reflecting the relationships between the entities;

software to be distributed, the software having a directory services object corresponding thereto and being independent from the directory services executable;

a distribution executable programmed to distribute the software;

a distribution object of the directory services objects, the distribution object corresponding to the software and containing attributes comprising distribution-controlling data to be used by the distribution executable for controlling distribution of the software.

10. The article of claim 9, wherein the data store is stored in a directory services memory of a directory services node in the network.

11. The article of claim 9, wherein the software is stored in a software object in a source node memory of a source node in the network.

12. The article of claim 9, wherein the distribution executable is stored in a workstation memory in a workstation node, in the network, to be executed by the workstation node.

13. The article of claim 12, wherein the actual entity is the workstation node.

14. The article of claim 9, wherein the distribution object further comprises an identifier corresponding to a software object.

15. The article of claim 9, wherein the distribution object further comprises a distribution list identifying targets selected from the logical entities and corresponding to actual entities to receive the distribution of a software object.

16. The article of claim 15, wherein:

the logical entities are interrelated in a hierarchy comprising a plurality of levels, each logical entity pertaining to a corresponding level; and

the distribution list contains targets selected from more than one of the levels.

17. The article of claim 9, wherein the distribution object further comprises scheduling data for controlling scheduling of the distribution of a software object.

18. The article of claim 17, wherein the scheduling data is effective to schedule a parallel distribution of the software object to a plurality of workstation nodes in the network.

19. A method for distributing software, the method comprising:

providing a network comprising nodes, including a directory services node, a source node, and a workstation node;

providing a network directory services system associated with the directory services node and comprising directory services objects having attributes managed by a directory services executable, each directory services object corresponding to an entity and operably related in a hierarchical tree to others of the directory services objects, the hierarchical tree reflecting the relationships between the entities;

providing in the source node in the network software, independent from the network directory services system, to be distributed;

providing a distribution object as one of the directory services objects, having attributes comprising distribution-controlling data; and

providing a distribution executable for accessing the distribution object and controlling distribution of the software in accordance with the distribution-controlling data.

20. The method of claim 19 further comprising:

providing for execution by the workstation node, the distribution executable programmed to distribute the software from the source node to the workstation node in accordance with the distribution-controlling data in the distribution object.

21. The method of claim 20, further comprising:

providing the software embodied as a software object; and

executing, by the workstation node, the distribution executable to distribute the software object.

22. The method of claim 21, wherein the distribution object contains an identifier corresponding to, and designating for the distribution, the software object.

23. The method of claim 21, wherein the distribution object further comprises a distribution list identifying targets, selected from the logical entities and corresponding to actual entities to receive the distribution of the software object.

24. The method of claim 23, wherein:

the logical entities are interrelated in a hierarchy comprising a plurality of levels each containing logical entities; and
