Document Type and Number:
Japanese Patent JP6527488
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily obtain a large scale network if a conventional router and interconnected OFS clusters are expanded.SOLUTION: An OFC 1 which controls OFS#1-#6, which are arranged on an internal NW connected to an external NW through a plurality of conventional router, to control packet transfer, includes: an internal NW route control unit 13, including RE 4-1 to 4-6 in each OFS#1-#6, which calculates a route to the internal NW; an external NW route control unit 12, including an RE 4-C in an OFS cluster 2 in which OFS#1-#6 are clustered, which calculates a route to the external NW; and a flow entry generation unit 113 which, in a flow entry generated for each OFS#1-#6, sets an outflow destination of a packet, to which a destination in the external NW is set, from the OFS cluster 2 to be an output IF of an OpenFlow switch which is connected to the conventional router to transfer to the destination in the external NW.SELECTED DRAWING: Figure 5
