Abstract: A time-interleaved analog to digital converter (ADC) circuit includes an input signal amplitude detector configured to determine an input signal amplitude of an analog input signal, a multi-tone signal generator configured to generate a plurality of analog and digital sinusoidal signals having an amplitude dependent on the determined input signal amplitude, and an analog input summing module configured to provide a summed output analog signal from the analog input signal and the analog sinusoidal signals. A time-interleaved ADC has an input coupled to receive the summed output analog signal from the analog input summing module and configured to provide a timing skew-calibrated digital output signal from the summed output analog signal. A digital output subtractor module is configured to provide a digital output signal at an output of the circuit from the digital output signal from the time-interleaved ADC and the digital sinusoidal signals from the multi-tone signal generator.

Abstract: The method for implementing mechanisms for Layer 7 context accumulation for enforcing Layers 4, 7, and verb-based rules is presented. The method comprises: receiving stream data, and identifying a packet in the stream. If the packet includes Layer 7 headers: for each Layer 7 header: determining content of the packet identified by a Layer 7 header's identifier; and parsing the content to extract firewall input data. If one or more rules at least partially match the firewall input data, determining that a particular rule also includes additional information that cannot be found in the firewall input data; performing a DPI on the content to determine whether at least a portion of the additional information is found in the content; extracting additional input data from the content and adding it to the firewall input data; and applying the rules to the firewall input data to process the packet.

Abstract: The method for processing interleaved Layers 4, 7 and verb-based rulesets is presented. The method comprises receiving stream data; identifying a packet in the stream; parsing the packet to extract firewall input data; and determining that one or more rules at least partially match the firewall input data. If any of the rules also include additional information not found in the firewall input data, a DPI is performed to determine whether a first portion of the additional information is found in the packet. If no first portion of the additional information is found, a full DPI is performed to determine whether a second portion of the additional information is found in the packet. If the second portion is found, additional input data is extracted from the packet, and added to the firewall input data. The rules are applied to the firewall input data to determine whether to transmit the packet.

Abstract: A method for monitoring network conditions by receiving a first condition definition describing a first network condition to be monitored in a network and an activation definition, determining a network topology of the network, and compiling the first condition definition to generate a first data plane component, a first control plane component, and an activation component. The method also includes deploying the first data plane component into a data plane of the network, where the data plane component captures and synthesizes a first stream of network events to generate a first modified stream of network events. The method also includes deploying the control plane component into a network operating system for the network. The control plane component receives and correlates the first modified stream of network events. The method also includes deploying an activation component that, upon receiving the correlated stream of events, initiates the activation definition.

Abstract: In one implementation, a network device is configured to implement an intra switch transport protocol. The intra switch transport protocol is configured to determine a window size according to a predetermined bandwidth and a round trip time between a plurality of ingress ports and an egress port. The network device is configured to sending at least one data packet from an ingress port to an egress port without first receiving any acknowledgement from the egress port. The network device continues to send packets and increment a counter accordingly until the counter reaches the window size. The network device ceases transmission of subsequent data packets and/or queues subsequent data packets based on the counter exceeding the window size.
