1. A packet data network traffic management device, comprising:

  • a plurality of ports;

    a plurality of micro-controllers, each of said micro-controllers operates to control packet data through a corresponding port of said plurality of ports, each of said micro-controllers is a deterministic micro-controller and comprises a first hardware thread to manage incoming data packets at its said corresponding port and a second hardware thread allocated to managing outgoing data packets at said corresponding port, each of said first and second hardware threads are managed by hardware of the deterministic micro-controller to execute an instruction of the first hardware thread to process an incoming data packet on alternating clock cycles with an instruction of the second hardware thread to process an outgoing data packet; and

    said plurality of deterministic micro-controllers selectively communicate data packets between said plurality of ports.
