INPUT LINE INTERFACE DEVICE AND PACKET COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce a post-stage processing load for performing routing control by efficiently housing the packets of a high speed line. SOLUTION: A packet assigning means 11 divides variable length packets, and assigns and outputs those variable length packets to parallel lines. Flow group classifying means 12-1 to 12-n classify the packets into flow groups for each of the parallel lines. A sequence number applying means 13 applies sequence numbers to the packets corresponding to the flow groups or independently. Buffering means 14-1 to 14-n perform the buffer storage and reading of the packets applied with the sequence numbers, and controls the arrangement of the packets in the flow groups. A flow assignment switch 15 assigns and outputs the packets to each flow group.
