Abstract

Replicating modifications of a directory that include receiving in a source directory service for a source directory requests for modifications in the source directory and transmitting, from the source directory service to a duplicate directory service for a duplicate directory asynchronously in parallel over a plurality of data communications connections, requests for the same modifications in the duplicate directory. In typical embodiments, a duplicate directory may replicate a subtree of a source directory, receiving requests for modifications may include receiving in the source directory service requests for modifications in the subtree in the source directory, and transmitting requests may include transmitting requests for the same modifications in the subtree in the duplicate directory.

Claims

1. A method for replicating modifications of a directory, the method comprising:

receiving in a source directory service for a source directory requests for modifications in the source directory; and

transmitting, from the source directory service to a duplicate directory service for a duplicate directory asynchronously in parallel over a plurality of data communications connections, requests for the same modifications in the duplicate directory.

2. The method of claim 1 wherein:

the duplicate directory comprises a subtree of the source directory;

receiving requests for modifications further comprises receiving in the source directory service requests for modifications in the subtree in the source directory; and

transmitting requests further comprises transmitting requests for the same modifications in the subtree in the duplicate directory.

3. The method of claim 1 further comprising identifying requests for related serial operations, wherein transmitting requests further comprises transmitting identified requests for related serial operations on the same data communication connection.

4. The method of claim 3 wherein requests for related serial operations further comprise a request to modify a schema of an entry and a subsequent request to modify the entry.

5. The method of claim 3 wherein requests for related serial operations further comprise a request to create or move an entry having a child and a subsequent request to modify the child.

6. The method of claim 3 wherein requests for related serial operations further comprise a request to delete or move a child of an entry and a subsequent request to modify the entry.

7. The method of claim 3 wherein requests for related serial operations further comprise a request to modify an entry and a subsequent request to modify the entry.

8. The method of claim 1 further comprising bracketing, by the source directory service, a plurality of requests as an atomic transaction, wherein transmitting requests further comprises transmitting bracketed requests of an atomic transaction on the same data communications connection.

9. An apparatus for replicating modifications of a directory, the apparatus comprising a computer processor and a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:

receiving in a source directory service for a source directory requests for modifications in the source directory; and

transmitting, from the source directory service to a duplicate directory service for a duplicate directory asynchronously in parallel over a plurality of data communications connections, requests for the same modifications in the duplicate directory.

10. The apparatus of claim 9 wherein:

the duplicate directory comprises a subtree of the source directory;

receiving requests for modifications further comprises receiving in the source directory service requests for modifications in the subtree in the source directory; and

transmitting requests further comprises transmitting requests for the same modifications in the subtree in the duplicate directory.

11. The apparatus of claim 9 further comprising computer program instructions capable of identifying requests for related serial operations, wherein transmitting requests further comprises transmitting identified requests for related serial operations on the same data communication connection.

12. The apparatus of claim 9 further comprising computer program instructions capable of bracketing, by the source directory service, a plurality of requests as an atomic transaction, wherein transmitting requests further comprises transmitting bracketed requests of an atomic transaction on the same data communications connection.

13. A computer program product for replicating modifications of a directory, the computer program product disposed upon a signal bearing medium, the computer program product comprising computer program instructions capable of:

receiving in a source directory service for a source directory requests for modifications in the source directory; and

transmitting, from the source directory service to a duplicate directory service for a duplicate directory asynchronously in parallel over a plurality of data communications connections, requests for the same modifications in the duplicate directory.

14. The computer program product of claim 13 wherein the signal bearing medium comprises a recordable medium.

15. The computer program product of claim 13 wherein the signal bearing medium comprises a transmission medium.

16. The computer program product of claim 13 wherein:

the duplicate directory comprises a subtree of the source directory;

receiving requests for modifications further comprises receiving in the source directory service requests for modifications in the subtree in the source directory; and

transmitting requests further comprises transmitting requests for the same modifications in the subtree in the duplicate directory.

17. The computer program product of claim 13 further comprising computer program instructions capable of identifying requests for related serial operations, wherein transmitting requests further comprises transmitting identified requests for related serial operations on the same data communication connection.

18. The computer program product of claim 13 further comprising computer program instructions capable of bracketing, by the source directory service, a plurality of requests as an atomic transaction, wherein transmitting requests further comprises transmitting bracketed requests of an atomic transaction on the same data communications connection.
