摘要： The method includes receiving, by a data plane definition language compiler, a first data plane definition describing customized functionality of a data plane of a first network application, and compiling the data plane definition to generate a first set of customized data processing modules and a program interface that allows a control plane of the network application to access the first set of customized data processing modules. The method also includes loading the first set of customized data processing modules into a data plane container, wherein the network application is executed via a network operating system, and wherein, upon execution of the network application the customized data processing module causes the data plane container of the network application to process packets differently than prior to loading the customized data processing module in the data plane container.

摘要： A content search system determines whether an input string matches a negative regular expression that includes a negative pattern and an optional positive pattern. If the input string matches the positive pattern and does not match the negative pattern, a match between the input string and the negative regular expression is indicated. The positive pattern and the negative pattern may be compared to the input string in a single pass of the input string. The content search system may be implemented in a content addressable memory (CAM) device. The negative regular expression may specify a particular portion of the input string, such as a range of characters or bytes of a data packet, in which the negative pattern should not match for a match between the negative regular expression and the input pattern to be indicated.

摘要： A content search system includes CAM device, a compiler, and an image loader. The CAM device, which includes a plurality of rows of CAM cells and a number of counter circuits selectively interconnected by a programmable interconnect structure (PRS), performs regular expression search operations. The compiler selectively converts the regular expression into a number of various bit groups, and the image loader loads corresponding bit groups into the CAM cells, into a number of memory elements that control configuration of the PRS, and into the counter circuits.

摘要： A content search system for determining whether an input string matches one or more rules includes a parser, a rules database, and a search engine. The parser, which has an input to receive the input string, is to extract one or more selected portions of the input string to form a filtered input string, and is to generate a rule select signal in response to the selected portions of the input string. The rules database stores a plurality of sets of rules. The search engine is to compare the filtered input string with a selected set of rules selected in response to the rule select signal.
