  • Patent number: 11575595
    Abstract: A digital crosspoint switch of a network switching system (NSS) replicates input data received via a first network interface to a first data processing port of a data processing card. The input data includes a digital market data feed comprising market-data packets. The crosspoint switch has internal crosspoint ports and external crosspoint ports. The data processing card includes a programmable logic device and a plurality of data processing ports connected to the internal crosspoint ports. The NSS includes a plurality of network interfaces connected to the external crosspoint ports. The data processing card processes the input data and generates processed data on the second data processing port at least in part by only including market-data packets that meet a first predetermined filtering criterion in the processed data. The crosspoint switch replicates the processed data from the second data processing port to the second network interface.

  • Patent number: 10917335
    Abstract: Method and systems for data switching, including receiving first input data at a network switching system comprising a crosspoint switch and a data processing card; transmitting the first input data from the crosspoint switch to the data processing card; making a first determination, by the data processing card, that the first input data meets a first pre-determined filtering criterion; and transmitting, based on the first determination, the first input data from a first crosspoint switch port of the crosspoint switch towards a first client.

  • Patent number: 9674118
    Abstract: A digital networking system includes a digital crosspoint switch, a host controller, and a data processing card that includes a programmable logic device such as a field-programmable gate array (FPGA). The host controller is operative to configure both the data processing card and the digital crosspoint switch in accordance with commands received over a user interface. The system is configurable to direct incoming data through the crosspoint switch to the data processing card for processing, and then back through the crosspoint switch for distribution to one or more network ports. The processing performed by the data processing card may include, among other options, feed filtering of a digital market data feed for use in high-frequency trading applications.
