ABSTRACT:
The present invention is provided with a pipeline for performing in a conveyor-belt style, the processing of obtaining the necessary information for performing an operation after judging the operation to be performed, of the Swap, the Push, and the Pop, and obtaining the output channel information, based on the content of the shim header of the MPLS packet and the information set in advance. The header controller sequentially supplies a top shim header of each packet received from a plurality of lines to the pipeline and performs an actual operation on the top shim header of each packet, based on the obtained information. As the result of the pop operation, when there exists a shim header that becomes a top newly, it repeats the above processing starting from a stage of supplying the shim header of the new top to the pipeline again. Namely, the pop processing of the MPLS packet is not collectively performed at once but performed by looping the pipeline.
