Abstract: The invention provides a method and apparatus for advanced network intrusion detection. The system uses deep packet inspection that can recognize languages described by context-free grammars. The system combines deep packet inspection with one or more grammar parsers (409A-409M). The invention can detect token streams (408) even when polymorphic. The system looks for tokens at multiple byte alignments and is capable of detecting multiple suspicious token streams (408). The invention is capable of detecting languages expressed in LL(I) or LR(I) grammar. The result is a system that can detect attacking code wherever it is located in the data stream (408).

Abstract: A classification method and system for possible content alteration of a media work may include criteria regarding content that is feasible for alteration. Such criteria may be maintained in records that are accessible to an interested party. Some embodiments may include a record of primary authorization rights applicable to a possible content alteration. A further embodiment feature may include a record of secondary authorization rights applicable to substitute altered content incorporated in a derivative version. Various exemplary techniques may be used to provide audio and/or visual substitution options in a derivative version of the media work in accordance with applicable alteration guidelines.

Abstract: A method for translating information of balancing loads among bus segments to provide a load balanced bus system. The method includes the steps of displacing bus connection balancing loads from a least significant bit location of a digital device bus by an offset factor and translating information between the balancing load and a the digital device bus within a switch by circularly shifting the information by a number of bits equivalent to the offset factor.
