Abstract:
A method and apparatus are provided for implementing frame alteration commands in a communications network processor. A set of frame alteration instruction templates is defined. A frame alteration instruction template is identified based upon the packet type recognition result of a received packet. A frame alteration instruction stream is generated utilizing the frame alteration instruction template. Each of the frame alteration instruction templates includes different frame alteration commands to be performed on a packet. Pointers to indirect data bytes to be inserted in a packet are stored in the frame alteration instruction templates. The generated frame alteration instruction stream is used by hardware to provide frame alterations.
