Abstract:
In a secure fast packet switch, having a plurality of input ports and a plurality of output ports, a method of determining which port in the plurality of output ports data that is received on one input port in the plurality of input ports is to be sent to, the method comprising the steps of:determining a physical layer address of a sending node;determining a physical layer address of a receiving node;determining an input port in the plurality of input ports that the data was received on;determining if the physical layer address of the sending node and the physical layer address of the receiving node are an allowed combination;determining a magnitude of a node identification number of the sending node;determining a magnitude of a node identification number of the receiving node;obtaining outbound port information from a first predetermined location in a data structure stored in a memory if the magnitude of the node identification number of the sending node is greater than the magnitude of the node identification number of the receiving node; andobtaining outbound port information from a second predetermined location in the data structure stored in the memory if the magnitude of the node identification number of the sending node is less than the magnitude of the node identification number of the receiving node.
