NETWORK PROCESSOR MIRROR IMPLEMENTATION METHOD AND NETWORK PROCESSOR

摘要

The present invention relates to a network processor mirror implementation method and a network processor. The method includes: a network processor acquiring the message head of an original message which enters a buffer unit from a source port, with the original message being allocated with an index number; carrying the index number within the message head and sending same to a micro-engine unit; performing microcoding on the message head, and acquiring exit information about a mirror from a pre-set mirror list according to the index number; and re-linking the original message in the buffer unit and the microcoded message head to form a mirror message, and sending same out from a mirror port indicated by the exit information about the mirror. The present invention takes advantage of the message forwarding flow in the relevant art to forward a mirror message, wherein the forwarding procedure of mirror messages is flexible and general purpose, having a stronger applicability, and being capable of saving system resources and costs.
