ONOS와 Raspberry Pi 기반 가상물리 SDN 실증 환경 구축과 응용 개발
The document provides information about setting up an SDN testbed using ONOS and Raspberry Pi. It introduces ONOS, an open source SDN operating system, and provides details on installing and running a single ONOS instance. It also covers setting up and managing multiple ONOS instances in a distributed deployment. Finally, it introduces OpenVirteX, a network virtualization platform, and provides an overview of its key features and the installation process.
