1. In a Private Network to network Interface (PNNI) based Asynchronous Transfer Mode (ATM) network a method of determining a complex node representation for a logical node in a peer group, said method comprising the steps of:

  • generating a list of border nodes located within said peer group, each border node corresponding to a port in said logical node;

    generating a plurality of tables, each table associated with a particular metric within a particular class of service, each table populated with a plurality of elements, each element representing an optimum metric between an associated pair of ports;

    dividing the total range for each metric into M bins representing a subrange of said total range and placing said plurality of elements in said bins in accordance with an element'"'"'s value;

    choosing a bin having an element count greater then a threshold and setting a default spoke value in accordance with the percentage of a value within the subrange of the bin corresponding thereto; and

    wherein M is a positive integer.
