<P>PROBLEM TO BE SOLVED: To make effective use of a band in link aggregation without changing the order of packets in flow units. <P>SOLUTION: A hash operation circuit performs hash operation on a received packet to determine one of selection circuits to be an output destination by using a hash value. A selection circuit control unit registers priority, hash operation, and hash value, etc. in flow units, or deletes registered items, in a selection circuit management table each time a new packet is received or according to an interrupt from a buffer circuit or an interrupt for link down information from a physical IF. The selection circuit on either side transmits, under control of the selection circuit control unit, a received packet to one of buffer circuits according to control information and priority. <P>COPYRIGHT: (C)2013,JPO&INPIT |
