1. A method for routing incoming messages across a boundary of a cluster of computer nodes, the cluster connected to one or more networks, comprising the steps of:

  • reading a software communication protocol number in a message header of the message to recognize an incoming message as a software communication protocol port type message, the message having a destination address of a gateway node within the cluster of computer nodes;

    locating and reading a software communication protocol port number in the message header of the software communication protocol port type message;

    matching both the software communication protocol port number and the software communication protocol number to an entry in a message switch memory, the matched software communication protocol port number entry being associated with a software communication protocol port specific function which selects a routing destination for the message from a plurality of possible destinations, the destination being a computer node in the cluster; and

    routing the message to the computer node destination.
