1. A method comprising the steps of:
- using a control point function located in a control ;
point processor to generate a guided frame;
using a device driver in said control point processor to send the guided frame to one of a plurality of media interfaces associated with a network processor;
using Medium Access Control hardware in said media interfaces to recover the guided frame;
storing the recovered guided frame in a memory; and
routing said stored guided frame to an entity identified in said guided frame.

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.
