Packet data traffic management apparatus

摘要

A packet data network traffic management device comprises a plurality of ports comprising at least a first port, a second port, and a third port; and a plurality of deterministic multi-threaded deterministic micro-controllers, each of the micro-controllers associated with a corresponding one of the ports to control packet data through the corresponding port; and the plurality of multi-threaded deterministic micro-controllers cooperatively operate to selectively communicate data packets between the plurality of ports.

1. A packet data network traffic management device, comprising:
a plurality of ports comprising at least a first port, a second port, and a third port; a plurality of deterministic multi-threaded micro-controllers, each of said deterministic multi-threaded microcontrollers associated with a corresponding one of said ports to control packet data through said corresponding port, each of said deterministic multi-threaded micro-controllers comprises a first hardware thread allocated to managing Incoming data packets on its said corresponding port and a second hardware thread allocated to managing outgoing data packets on said corresponding port, each of said first and second hardware threads are managed in hardware such that each thread executes an instruction on alternating clock cycles; a single memory, said single memory configured such that packet data from each of said plurality of ports may be routed therethrough; and said plurality of deterministic multi-threaded micro-controllers cooperatively operate to selectively communicate data packets between said plurality of ports.
