Abstract

Abstract: The QoS-enabled measuring and routing system is designed and realized by adopting the OpenFlow. The abilities of measuring link delay， load and packet loss are realized by utilizing the interactive messages between the controller and the OpenFlow-enabled switch. In order to solve the problem of multiple constraints during QoS routing， a multiple constraints routing algorithm is improved and realized with the QoS metrics (link delay， load and packet loss) considered. The experimental results show that the system proposed is able to measure the QoS metric and change the routing path based on QoS measurement， and it meets the needs of system design.

Key words: OpenFlow, SDN(software defined networking), QoS measurement, routing arrangement, multiple constraints
