    Emerging Software-Defined Networking (SDN) paradigm has been widely affecting most networking fields. However, the real-world SDN application for inter-domain routing management is still limited since the routing exchange among wide-area networks is quite complicate due to the extreme scale of global Internet connectivity. Several SDN-leveraged routing ideas are being proposed to improve the routing exchange among wide-area networks. Thus, in this paper, an on-going experience for experimenting and validating the inter-domain routing proposals over OF@TEIN federated testbed in Asia is shared. By focusing on the design and implementation of monitoring deployment for visibility support, we try to identify practical key points and provide improved monitoring for validating the performance and anomaly of the exchange. Other design considerations are also discussed together with possible future research directions

    Deploying and Evaluating OF@TEIN Access Center and Its Feasibility for Access Federation

    For the emerging software-defined infrastructure, to be orchestrated from so-called logically centralized DevOps Tower, the shared accessibility of distributed playground resources and the timely interaction among operators and developers are highly required. In this paper, by taking OF@TEIN SDN-Cloud playground as a target environment, we discuss an access center effort to address the above requirements. In providing the developer presence via the proposed access center, the inherent heterogeneity of internationally dispersed OF@TEIN resources is setting a unique challenge to cope with the broad spectrum of link bandwidths and round-trip delays. The access capability of deployed access center is experimentally verified against a wide range of access network conditions, which would be extended for futuristic access federation with appropriate identity management and resources abstraction for multiple developers and operators

    Leveraging ONOS SDN Controllers for OF@TEIN SD-WAN Experiments

    In this paper, we discuss on-going experiments at OF@TEIN Playground to evaluate the feasibility of SD-WAN (software-defined wide area network) solutions by leveraging open-source ONOS (open network operating systems) SDN controller. In order to explore efficient solutions in building SDN-enabled WAN, we utilize distributed cloud-based resources to inter-connect them by employing legacy-friendly L3 routing instead of L2-focused overlay tunnels
