Introduction of ONOS and core technology
This document provides an overview of ONOS (Open Network Operating System) including: - ONOS is an open-source SDN controller created by ON.LAB to provide carriers with an SDN/NFV solution. - It aims to be carrier-grade with high availability, scalability, and performance through a distributed architecture. - ONOS uses southbound protocols like OpenFlow and Netconf to configure network elements while providing northbound APIs and applications.
