A method and apparatus for processing network frames by embedding control information achieves an efficient frame processing system within a network processor (NP). The layer type of the frame can be quickly determined by the layer processing components of picocode running on the NP by examining control...http://www.google.ca/patents/US6760776?utm_source=gb-gplus-sharePatent US6760776 - Method and apparatus for processing network frames in a network processor by embedding network control information such as routing and filtering information in each received frame
