Title:
CONTROLLER, NETWORK SYSTEM, AND FLOW MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/181541
Kind Code:
A1
Abstract:
A reception unit (210) receives an addition request frame for requesting the addition of a new flow. When the addition request frame is received, a first search unit (241) uses a network information database (280) to perform a first search that searches for a scheduling and a path that are assignable to the new flow without changing the schedulings and paths of the existing flows. When no scheduling and no path that are assignable to the new flow are found by the first search, a second search unit (242) uses the network information database to perform a second search that searches for a scheduling and a path that are assignable to the new flow by changing the schedulings and paths of the existing flows. A response unit (260) transmits an addition response frame.
