  • Amortizing dissipated power and current demand in a ternary content addressable memory
    Patent number: 10825521
    Abstract: To use larger capacity TCAMs while avoiding various packaging and power management issues of TCAMs, pre-processing can be performed on TCAM lookup requests to intelligently pipeline lookup requests according to a defined power budget that is based on TCAM and power supply specifications. Dividing lookup requests based on a power budget smooths the instantaneous current demand and dynamic power demand. This intelligent pre-processing of lookup requests allows lookup requests that satisfy a power budget based threshold to still complete within a single clock cycle while nominally reducing performance for those lookup requests that would not satisfy the power budget based threshold. When a lookup request will not satisfy the power budget based threshold, the lookup request is split into searches targeting different memory blocks of the TCAM.

  • Network device implementing two-stage flow information aggregation
    Patent number: 9906495
    Abstract: A network security device includes a network flow statistics processing engine to process network flow information related to network flows. The network flow statistics processing engine includes a first processing stage performing per-flow information aggregation and a second processing stage performing per-destination system component information aggregation, with each processing stage implementing a threshold-based data export scheme and a timer-based data export scheme. In this manner, up-to-date flow information is available to peer system components regardless of the varying flow rates of the network flow.
