FPGA Hardware Classifiers
Classification is the process of taking a single data stream in and sorting it into
multiple output substreams. The classifier engine on an E Series router is a
combination of PowerPC processors, working with an FPGA for a hardware assist.
In the Differentiated Services (DiffServ) architecture, two basic types of classifiers
exist. The first classifier type is a multifield (MF) classifier. The MF classifier can
examine multiple fields in the IP datagram header to determine the service class to
which a packet belongs.
