通信システムおよびトポロジー情報作成方法
Document Type and Number:
Japanese Patent JP5644775
Kind Code:
B2
Abstract:
Provided is a communication system that includes a plurality of packet transfer units and a control unit which controls each packet transfer unit, in the communication system of which, a communications network used for each packet transfer unit to transfer packets, and a communications network used for the control unit to control each packet transfer unit can be integrated into one kind. The control unit transmits a reply request to each packet transfer unit. The packet transfer unit, upon receiving the reply request, transmits the reply request from a port other than that through which the packet transfer unit has received the reply request. Upon receiving the reply request, the packet transfer unit also returns a reply including information on ports of the local packet transfer unit, the reply being transmitted through a path for the control unit. On the basis of the reply transmitted from each packet transfer unit, the control unit creates topology information, the topology information including port interconnection information relative to ports provided at the control unit and each port of the packet transfer units.
