Document Type and Number:
Japanese Patent JP6578222
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To quickly select a route that hardly causes congestion even if two communication devices communicate on the route via a communication network.SOLUTION: A route selection device 1 lets two communication devices C3 and SV communicate with each other using an indirect route via a particular transfer device OFSex. Then, the route selection device obtains communication speed flow_bps of the communication, communication speed of communication being performed on a direct route not going through the particular transfer device OFSex, and the limit of communication speed on the direct route. Then, the route selection device determines whether or not total of communication speed of communication being performed and communication speed of communication on the indirect route is equal to or less than the limit of communication speed. If the total is equal to or less than the limit of communication speed, the direct route is selected as a route used for communication between the two communication devices C3 and SV.SELECTED DRAWING: Figure 1
