Abstract:
To detect performance degradation and identify causal links promptly in OpenFlow networks, this paper presents the design of a scheme to actively measure the performance of all physical links from a single measurement point based on the controllable feature of individual traffic flow provided in OpenFlow. In the scheme, the measurement paths from a measurement box (called a “beacon”) are calculated to comprehensively cover all links and the probing packets are transmitted along elaborately defined routes in cooperation with the OpenFlow controller and multiple switches. Diagnosing the link performance of an entire OpenFlow network with a single beacon is expected to reduce operational costs, such as deployment and maintenance costs of beacons. In addition, reducing the number of flow-entries for active measurements on OpenFlow switches is considered to save the resources of OpenFlow switches. The effectiveness and feasibility of our solution are demonstrated through model emulations.
