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.

Abstract: A method and apparatus for displaying locally stored content objects is disclosed. In one embodiment, the method comprises receiving a message containing one or more parameters indicative of one or more characteristics of a client, and sending one of a plurality of groups of one or more content objects from a set of content objects to the client based on the one or more parameters, wherein each of the plurality of groups is suited for use with clients having a different set of one or more parameters.

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.

Abstract: A method and apparatus for peer-to-peer video precaching is described. In one embodiment, the method comprises building a user profile, periodically checking for new content of objects in the user profile, maintaining a data base of available objects and location of said objects, and determining the download location of an object requested by a user.

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.
