Abstract: A network packet broker comprising a plurality of source ports for receiving incoming data packets, a plurality of destination ports for transmitting outgoing data packets, a switch chip arranged to direct incoming data packets from a source port to a destination port based on a configurable set of rules, and a port for receiving a configuration model from a user interface. The configuration model comprises a set of maps and a set of filters, each map specifying at least one source port and at least one destination port, and each filter specifying a condition under which a packet of interest may pass the filter. A rule generator is provided to convert the configuration model into a set of rules for configuring the switch chip. The rule generator is arranged to convert a plurality of maps into a set of rules which the switch chip can implement in one pass.
