| Abstract(in English) | For network optimization and high-availability based on SDN, it is required to monitor the state and quality of every link in real time, and the active measurement, in which probe packets flow over all links, is essential. We previously proposed a framework of network-assisted location of lossy links on OpenFlow networks. In the framework, a series of multicast probe packets are transferred along a measurement route covering every full-duplex link in each direction only once; and then the controller retrieves the number of arrivals of those packets at input ports on different switches and compares them to locate high loss-rate links. To reduce the number of accesses to switches until locating all lossy links by efficiently narrowing the possible locations of lossy links, a trade-off between the number and length of terminal paths in the measurement route should be controlled. Therefore, in this paper, we propose an Eulerian cycle-based design of measurement routes and show it finds a proper route to reduce the number of accesses to switches depending on the size of networks and the packet loss rates of normal links. |
