As Wireless, Wireline and Cable service providers transform their networks with the deployment of SDN and NFV, the challenge of network planning moves from an individual network function perspective to that of the Network Functions Virtualization Infrastructure (NFVI) perspective. This course is focused on the computer, networking, and storage requirements that the NFVI needs to support to operate and deploy all the VNFs. The course covers the fundamental differences in planning between PNF and VNF for capacity, availability, and reliability as well as application performance. Student team and lab-based exercises will reinforce the course material. The class is focused on student hands-on exercises. The exercises will be both workbook team-based exercises as well as interactive lab exercises. The lab exercises will focus on the role OpenStack Heat and Ceilometer play in automating the virtualized network performance and reliability activities.

This session is intended for leaders in technology organizations interested in learning about the technologies and drivers for Network Virtualization at Wireless, Wireline and Cable service providers.

After completing this course, the student will be able to:
• Illustrate the difference in network planning of PNFs and VNFs
• List the resource planning models for compute, network, and storage of the NFVI
• Demonstrate the role of OpenStack Heat and Ceilometer in managing a virtualized network
• Compare and contrast the VNF deployment options on NFVI planning
• Identify the role of SDN on network resource planning
• Illustrate the impact of orchestration on NFVI planning including the resources required to run the NFV-O
• List impact of the deployment and architectural choices on NFVI resources
