| Abstract(in English) | In recent year, OpenFlow is becoming popular as a technology supporting cloud services and server virtualizations.Accordingly, in order to maintain a high quality of large-scale OpenFlow networks, active measurement-based real-time performance and status monitoring schemes have been studied.Our previous study focused on the packet loss rate of each link on an OpenFlow network as an indicator of communication quality.In this report, we focus on the packet delay variation as an indicator of communication quality and propose a method to efficiently monitor the packet delay variation of each link in both direction.In the proposed method, measurement packets are multicast-transferred traversing all links in both directions from a measurement terminal at a constant time interval and each switch acquires statistics of the arrival time interval of the measurement packets, which can be used to estimate the link packet delay variation.We also efficiently identify the links with large delay variations (larger than a threshold) by an appropriate order of retrieving the observed statistics from switches.Its effectiveness has been shown through simulation on a large-scale network topology.We also have investigated the impact of the position of the measurement terminal. |
