System and method for parsing frames

摘要

A system for parsing frames including a first cell extraction circuit (CEC) configured to identify a first cell from a first frame, a first parser engine operatively connected to the first CEC, where the first parser engine is configured to generate a result based on the first cell, and a first forwarding circuit operatively connected to the first parser engine and configured to forward the result, where the first CEC, the first parser engine, and the first forwarding circuit are associated with a first frame parser unit.

1. A network system for processing frames, comprising:
an input block coupled to a data cross-connect network and able to receive data organized in a stream of frames; and a frame parser ring coupled to the input block and configured to generate a plurality of frame results in accordance with the stream of frames, wherein the frame parser ring includes a plurality of frame parser units organized in a logically ring shaped structure with a priority, wherein the frame parser ring includes a first frame parser unit having highest priority in the frame parser ring and a second frame parser unit having lowest priority in the frame parser ring, wherein the first frame parser unit receives a first frame of the stream of frames and the second frame parser unit outputs at least a portion of the first frame with a first result.
