<p><P>PROBLEM TO BE SOLVED: To provide a communication system capable of preventing increase of control loads of a path controller by repeatedly setting packet transfer rules to the same packet transfer device in a short time to appropriately set the packet transfer rules to the respective packet transfer devices. <P>SOLUTION: A packet transfer rule generation means 91 generates the packet transfer rules including timer values. A packet transfer device management means 92 sets the packet transfer rules generated by the packet transfer rule generation means 91 to the packet transfer devices 95. In addition, the packet transfer rule generation means 91 differentiates the timer values of the packet transfer rule to packet transfer devices in a section for every section to be determined by dividing a communication path of a packet. Each packet transfer device 95 performs processing to the received packet according to the packet transfer rule during an effective period to be determined by the timer values of the set packet transfer rules. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
