PACKET RELAY APPARATUS, PACKET TRANSFER METHOD, AND COMMUNICATION SYSTEM

摘要

A packet relay apparatus having one or more communication interfaces coupled to a network, a processor coupled to the one or more communication interfaces, and a memory coupled to the processor, said packet relay apparatus holds path information including a plurality of combinations of a final destination and a next transfer destination of a packet, and conditions for applying individual combinations of the path information; determining, on the basis of information included in a received packet, whether or not the received packet satisfies the condition for applying each combination of the path information; and transferring the received packet to one or more next transfer destinations of one or more combinations of the path information associated with the condition determined to be satisfied and including a final destination identical to final destination information included in the received packet.

1. A packet relay apparatus comprising:
one or more communication interfaces coupled to a network; a processor coupled to the one or more communication interfaces; and a memory coupled to the processor, wherein the packet relay apparatus holds path information including a plurality of combinations of a final destination and a next transfer destination of a packet and conditions to apply individual combinations of the path information, and wherein the packet relay apparatus is configured to:
determine whether a received packet satisfies any of the conditions to apply individual combinations of the path information based on information included in the received packet; andtransfer the received packet to one or more next transfer destinations of one or more combinations of the path information associated with a condition determined to be satisfied and including a final destination identical to final destination information included in the received packet.
