Abstract

A system and method is provided for optimizing a SyncML slow sync between a proprietary client and server. When a slow sync is detected, the client and server can depart from the normal SyncML protocol and process summary data without having to compare all items on a field-by-field basis.

Claims

1. A method for optimizing a slow synchronization between a client and a server, comprising:

sending, by the server to the client and responsive to receiving a synchronization package having missing or corrupt synchronization anchors, a request to initiate a slow synchronization process;

receiving, by the server, a slow synchronization package;

determining, by the server and from the slow synchronization package, whether the client is designated proprietary; and

processing, by the server and only upon the client being designated proprietary, the slow synchronization package, wherein

the slow synchronization package includes only summary data related to documents stored at the client.

2. The method of claim 1, wherein

the summary data includes a unique identifier and a timestamp associated with the documents.

3. The method of claim 1, wherein

the summary data does not include the documents.

4. The method of claim 1, wherein

the request to initiate the slow synchronization process includes a request to the client to send all of the documents stored at the client.

5. The method of claim 1, wherein

the processing the slow synchronization package deviates from the slow synchronization process.

6. The method of claim 1, wherein

the client sends the summary data only upon the server being designated proprietary.

7. The method of claim 1, further comprising:

comparing, by the server, a unique identifier and a timestamp, obtained from the summary data, for each document stored at the client, with a unique identifier and a timestamp for each document stored at the server; and

sending, by the server to the client and based upon a determination of a mismatch, a status indicating a document to be sent to the server by the client.

8. A computer hardware system configured to optimize a slow synchronization between a client and a server, comprising:

at least one processor, wherein the at least one processor is configured to initiate and/or perform;

sending, by the server to the client and responsive to receiving a synchronization package having missing or corrupt synchronization anchors, a request to initiate a slow synchronization process;

receiving, by the server, a slow synchronization package;

determining, by the server and from the slow synchronization package, whether the client is designated proprietary; and

processing, by the server and only upon the client being designated proprietary, the slow synchronization package, wherein

the slow synchronization package includes only summary data related to documents stored at the client.

9. The system of claim 8, wherein

the summary data includes a unique identifier and a timestamp associated with the documents.

10. The system of claim 8, wherein

the summary data does not include the documents.

11. The system of claim 8, wherein

the request to initiate the slow synchronization process includes a request to the client to send all of the documents stored at the client.

12. The system of claim 8, wherein

the processing the slow synchronization package deviates from the slow synchronization process.

13. The system of claim 8, wherein

the client sends the summary data only upon the server being designated proprietary.

14. The system of claim 8, wherein the at least one processor is further configured to initiate and/or perform:

comparing, by the server, a unique identifier and a timestamp, obtained from the summary data, for each document stored at the client, with a unique identifier and a timestamp for each document stored at the server; and

sending, by the server to the client and based upon a determination of a mismatch, a status indicating a document to be sent to the server by the client.
