PROBLEM TO BE SOLVED: To provide a route selection device capable of efficiently selecting a traffic communication route that guarantees SLA.SOLUTION: Next hop node selection means 91 stochastically selects a next hop node from among a plurality of next hop node candidates on a hop-by-hop basis from a traffic transmission source node as a start point. When one next node is selected, performance determination means 92 determines whether or not communication performance in a route from the transmission source node to the next hop node satisfies a criterion provided in a service level agreement. If the communication performance is determined to satisfy the criterion, the next hop node selection means 91 further selects a subsequent next hop node. If the communication performance is determined not to satisfy the criterion, the next hop node selection means 91 starts afresh the next node selection from the selection of a next hop node to the transmission source node. |
