| 摘要 |
The invention reduces load on a controller (control apparatus) accompanying propagation of path information when a centrally controlled network and an existing network are connected. A communication system is provided with: a plurality of communication nodes; a control apparatus that controls the plurality of communication nodes based on path information collected using an internal border gateway protocol; and a path information processing apparatus that is provided with: a first path information processing unit that receives, via communication node(s) connected to an other autonomous system, among the plurality of communication nodes, path information from the other autonomous system using an external border gateway protocol, and a second path information processing unit that reports the path information received by the first path information processing unit to the control apparatus using an internal border gateway protocol. |
