The Developing Applications for ONOS training is a three-day hands-on program designed to enable participants to design, develop, and deploy custom applications on the Open Network Operating System (ONOS) controller. This course focuses on ONOS architecture, intent-based networking, controller APIs, and real-world SDN application development, empowering learners to build scalable, programmable, and production-ready network control applications.

• Understand the architecture, components, and software-defined networking capabilities of ONOS for network application development.
• Set up and configure ONOS development environments for SDN-based application development.
• Develop network applications using ONOS APIs, services, intents, and controller-based programming models.
• Implement topology discovery, traffic management, flow control, and network policy automation.
• Debug, test, and optimize ONOS applications for scalability, reliability, and network performance.
• Build scalable, secure, and production-ready SDN applications using ONOS development best practices.
