1. A method for converting data packets between a plurality of different packet formats including a first packet format, a second packet format, and a predefined generic packet format, comprising:

  • receiving a first data packet from a communication port, wherein said first data packet has said first packet format;

    a first processor converting the first data packet having said first packet format to a data packet having said predefined generic packet format, wherein said first processor converting the first data packet having said first packet format to said data packet having said predefined generic packet format is operable to convert a data packet having any of said plurality of different packet formats to the predefined generic packet format;

    the first processor providing said data packet having said predefined generic packet format to a crossbar switch;

    the crossbar switch selectively routing said data packet having said predefined generic packet format to a second processor;

    the second processor retrieving the data packet having said predefined generic packet format from said crossbar switch;

    the second processor converting the data packet having said predefined generic packet format to a second data packet having said second packet format, wherein said second processor converting the data packet having said predefined generic packet format to said second data packet having said second packet format is operable to convert the data packet having said predefined generic packet format to a data packet having any of said plurality of different packet format;

    providing said second data packet having said second packet format out a communication port.
