<p>Any policy route control defined in a virtual network (VN) configuration is realized without packet transfer to the controller when a new flow occurs. Specifically, in VN, regarding the policy route control by which a redirect is performed between a virtual interface (VI) corresponding to a physical switch (PS) and VI defined only on a virtual node, the physical interface linked to the transfer destination of VI is specified to set a switch operation as the policy filter in PS. When redirect transfer is performed in VN based on a policy, it is determined whether the static setting or the dynamic setting triggered by a terminal detection is performed, based on the information regarding whether the VN policy is a rule corresponding to an actual PS port or not, and the transfer rule corresponding to the policy is preliminary set to the flow table determining the switch operation of PS.</p> |
