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.
