Appl. No.:

11/089844

Inventors:

Allen Samuels - San Jose CA, US
Paul Sutter - San Francisco CA, US
Robert Plamondon - Blodgett OR, US

Assignee:

Orbital Data Corporation - San Mateo CA

International Classification:

H03M 7/34
H03M 7/38

US Classification:

341 51, 341 65, 341 67, 707102, 707204

Abstract:

A compression method and apparatus identifying candidates for compression by selectively fingerprinting shingles or overlapping subsets of an input dataset and creating a set of characteristic input fingerprints based on fingerprint value. In some cases, the characteristic fingerprints are selected based on the relative value of the fingerprints with respect to other fingerprints in the same cluster. Potential matches may be identified and confirmed by comparing the characteristic input fingerprints with fingerprints associated with a history. Advantageously, some examples according to the current invention may be applied to input data such as: data, files, bit streams, byte streams, packet streams and previously encoded, compressed and/or encrypted data. In some cases, the number of fingerprints selected per cluster, the cluster size, the shingle size or shingle configuration, the size or configuration of the overlap between successive shingles, and the configuration for adding entries to a history, may be adaptively configurable.

International Classification:

H04L 12/28
H04L 12/56

US Classification:

370394

Abstract:

The integrity of a data stream transmitted over a network is protected by adjusting the sequence number, the port number, or another field of a data packet field, for a number of data packets so that the data packets will be considered either valid or invalid by a downstream receiving device. Data packets that have such a field adjusted can be thought of as being rotated outside of a valid range or window, as defined for a network connection. This field of a rotated data packet can be further adjusted, through de-rotation or re-rotation, for various applications. Downstream devices can thus respond to the data packets depending on the state of the rotation.

International Classification:

H04L 12/56
G08C 25/02

US Classification:

370394, 714748

Abstract:

One or more flow control modules, implemented on various types of network topologies, provide a number of functionalities for controlling the flow of IP packets (such as TCP/IP packets) over a network connection. The flow control modules may be implemented within a sender and/or receiver or may be deployed into a network as a separate device without requiring significant additional resources.

US Classification:

37039521, 370412, 370433

Abstract:

A method and system for optimizing network traffic settings and for providing information on projected optimization of transformed traffic for a network includes: providing a traffic descriptor for sampled traffic data of the network; transforming the traffic data and extracting information on the transformed traffic data; and providing the traffic descriptor and the information on the transformed traffic data for analysis. The information can be a transformation traffic descriptor or a delta between untransformed and transformed network traffic. The traffic data and the transformed traffic data can then be modeled based the traffic descriptor and the information, respectively. Bandwidth requirements and quality of service settings for optimizing network performance for a service level can be provided based upon the traffic data model. Information on projected optimization of transformed network traffic can also be provided for the service level based upon the transformed traffic data model.
