Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for generating a new routing path through the router of a packet network by permitting respective filter rules generated based on the path on a packet flow through the router to regulate a physical path through the router. SOLUTION: A path related to respective packet flows is decided based on service quality supply information and network topology information. The group of single or plural filter routers is generated concerning the pertinent router based on the path related to the packet flow through the router. Respective filter rules regulate the physical path through the pertinent router. The selected filter rule is applied to the respective packets of the packet flow and the respective packets pass through the corresponding path through the pertinent router. In a network 100, for example, the routers 102-107 decide a logic path based on a multi-commodity flow routing method.
