Abstract
In a routing switch a technique for routing messages from an input port to an output port involves storing a plurality of sets of routing information in the routing switch, each set associated with a value of a header of the message. The technique involves grouping outputs which are suitable for outputting the same message. In the routing network, unicast packets include multiple headers and multicast packets include single headers. Sequence numbers of packets in the message are encoded in the packets by use of a longitudinal checksum. In the routing switch, messages are prioritized for routing in dependence on a priority allocated to the respective header.
