Appl. No.:

10/875792

Inventors:

Daniel R. Seligman - Needham MA, US
David L. Shepard - Marlborough MA, US
Mark W. Sylor - Nashua NH, US

Assignee:

Computer Associates Think, Inc. - Islandia NY

International Classification:

H04L 12/42

US Classification:

370449, 370503

Abstract:

A method of processing data received at a local system in response to polling a remote device, wherein the local system includes a local clock, the method involving: sending a first poll to the remote device; receiving a response from the remote device to the first poll, the response to the first poll containing data and a time stamp indicating when the remote device responded to the first poll; for the data received in response to the first poll, computing a first time by using both a time that was derived from the local clock for a previous poll of the remote device and also the time stamp contained in the response to the first poll; comparing the computed first time to information that the local system stored in connection with the first poll, wherein the information that the local system stored in connection with the first poll was derived from the local clock; and determining how to process the data received in response to the first poll based on comparing the computed first time to the information that the local system stored in connection with the first poll.

International Classification:

H04L 12/28
G06F 15/173

US Classification:

Abstract:

A method of merging a list of newly found network elements and a list of previously known network elements includes arranging the newly found network elements in a hierarchical structure, and determining one or more device matches between each network device in the list of newly found network elements and one or more network devices in the list of previously known network elements. The method further includes, for each of the one or more device matches, determining one or more network element matches between the newly found network element and the corresponding previously stored network device. The method also includes updating the previously found network device corresponding to each of the one or more device matches with the corresponding newly found network device.

International Classification:

G06F 17/30

US Classification:

707634

Abstract:

The present invention provides a method, system and computer program product for replication control using eventually consistent meta-data. In an embodiment of the invention, a method for replication control using eventually consistent meta-data is provided. The method includes replicating data in a replication data processing system of nodes coupled to one another over a computer communications network. The method also includes replicating meta-data representing the state of the replication data processing system into a data structure of eventually consistent meta-data. Finally, the method includes managing the replication of the data according to the replicated meta-data.
