<p><P>PROBLEM TO BE SOLVED: To provide a network node capable of reducing an increase in the load of a virtual node and a decrease in data transfer performance. <P>SOLUTION: The network node 1 includes: a tunnel switch 11 for discriminating whether traffic from the external is general traffic or overlay traffic; a flow table 14b for associating the header information of a packet with the processing contents of the packet and recording both as a flow entry; and an overlay flow monitoring function 113 for monitoring an input port in the tunnel switch and the processing contents of the packet of the overlay traffic in the tunnel switch and recording the monitored results in the flow table 14b, wherein the network node processes the packet of the overlay traffic in the tunnel switch based on reference results of the flow table with the header information extracted from the packet of the overlay traffic as a retrieving key. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
