COMMUNICATION NODE, CONTROL DEVICE, COMMUNICATION SYSTEM, PACKET PROCESSING METHOD, AND PROGRAM

摘要

In exercising role-based access control in a centralized control network, the load imposed on a control apparatus or a communication node is to be suppressed. A communication node comprises: a first table for matching against first information in a header of a packet received and deciding an attribute or a right of a source of the packet; a second table for matching against second information in the header of the packet received and finding content of processing for the packet from the source of the packet having the attribute or the right as decided using the first table; and a packet processing unit that, on receipt of the packet, decides the attribute or the right of the source of the packet, using the first table, and that thereafter finds, using the second table, the content of processing for the packet from the source of the packet having the attribute or the right as decided using the first table.
