Abstract: A quaternary content-addressable memory includes multiple entries configured to match a lookup word, with each of these entries including multiple cells and with the lookup word including multiple lookup bits for matching corresponding cells of each of the entries. Each of the cells is individually configurable to be in one of multiple states identified by two bits, with these states including a first matching state for matching a value of a corresponding bit of the lookup word with the value having a first matching value, a second matching state for matching the value of the corresponding bit having a second matching value, a wildcard state for matching the value of the corresponding bit having either the first or the second matching value, and an ignore state for indicating to ignore the cell in determining whether or not the entry to which the cell belongs matches the lookup word.

Abstract: Methods and systems for implementing a switch box (S-box) in a cryptographic application are described. An input to the S-box is converted from a Galois field representation GF(N2) to a Galois subfield representation GF(N)2. The input is converted using a generating polynomial of the form x2+Ax+B, where A and B are elements in GF(N) and where A has a value other than unity. The multiplicative inverse of the Galois subfield representation GF(N)2 is determined. The multiplicative inverse is converted back to the Galois field representation GF(N2). An affine transformation of the multiplicative inverse is then performed.

Abstract: Weighted random scheduling is preformed, which may be particularly applicable to packet switching systems. For each particular input of multiple switch inputs, a request to send a packet to one of the outputs of the switch is generated by weighted randomly selecting one of the outputs to which the particular input has one or more packets to send. One of the requests is granted for each different one of the outputs for which one or more requests were generated. Packets are sent between the inputs and the output corresponding to the granted requests. The weighted random selection is typically weighted based on the number of packets or bytes to send to each of the outputs by a corresponding input of the inputs, the last times packets were sent from a corresponding input of the inputs to each of the outputs, and/classes of service associated with packets to send to each of the outputs by a corresponding input of the inputs.

Abstract: 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.

Abstract: A present invention Galois field multiplier system and method utilize lookup tables to generate one partial product term and one feedback term in one clock cycle. In one embodiment, a Galois field multiplier system includes a plurality of shift registers, a plurality of exclusive OR components, a partial product lookup table, and a feedback table lookup table. The plurality of shift registers perform shift multiplication operation and are coupled to the plurality of shift registers that perform addition operations. The partial product lookup table and feedback lookup tables are selectively coupled to the exclusive OR components and values from the partial product lookup table and feedback lookup tables are fed into the selectively coupled exclusive OR components. Coefficients of the partial product term and feedback term are utilized as indexes to the partial product lookup table and feedback lookup table respectively.
