<p><P>PROBLEM TO BE SOLVED: To send an encrypted IP packet out to a communication path having QoS, corresponding to the service of the IP packet, without having to send any request to a device providing the service at all. <P>SOLUTION: A relay device transfers an IP packet as a packet, obtained by encapsulating an encrypted capsule packet using a capsulated header from a first device to a second device associatively stores encryption information associated with encryption used by the first device to generate the IP packet and route information showing a path to the second device; and determines a route to the second device, based on the encryption information contained in a capsulated header of an IP packet received from the first device. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
