1. A communications device comprising:
- a control point processor subsystem; and
a network processor, operatively coupled to said control point processor, including;
N interface processors, N>
1;
a plurality of media interfaces;
a plurality of queues coupling the interfaces to the processors wherein the queues provide channels through which data enters and leaves the processors;
memory that stores data passing through said control processor; and
euqueue/dequeue scheduler responsive to control signal to move data from the memory to a selected queue; and
said control point process or subsystem including;
control point function generator that generates and forwards to one of said plurality of media interfaces a guided frame with information that allows said control point processor subsystem access to registers and memories under control of said network processor.

Abstract
A network switch apparatus, components for such an apparatus, and methods of operating such an apparatus in which data flow handling and flexibility is enhanced by the cooperation of a control point and a plurality of interface processors formed on a semiconductor substrate. The control point and interface processors together form a network processor capable of cooperating with other elements including an optional switching fabric device in executing instructions directing the flow of data in a network.
