Communication Service Providers’ networks are evolving to virtualized network with deployment of VNFs in the cloud through automation and orchestration. In this workshop, students explore the SDN based cloud connectivity framework and NETCONF/YANG modeling for network configuration. Students steps through various mechanism for underlay and overlay connectivity within a data center for VM connectivity. Once the students have the foundation of all network configuration and troubleshooting related artifacts, they go through various break-fix scenarios to build the problem isolation skills through hands-on exercises.

This course is intended for a technical audience in planning, engineering, deployment, operations, and performance monitoring that has knowledge of packet networking.

After completing this course, the student will be able to:
• Sketch an end-to-end SDN architecture for Service Provider Network
• Sketch the SDN architecture and interfaces and identify protocols for these interfaces
• Understand the role of YANG and NETCONF in configuration of networking appliances
• Step through the data center connectivity and the role of underlay and overlay networks from the perspective of Provider and Tenant
• Identify issues related to basic connectivity for a VM
• Isolate connectivity issues related to VM-VM communication in intra-host and inter-host scenarios
