The document outlines a methodology for pre-deployment validation of Network Functions Virtualization Infrastructure (NFVI) to ensure it meets the requirements for Virtual Network Functions (VNFs). It emphasizes the importance of early detection of faults and bottlenecks using simple test cases and provides a flexible testing framework called Yardstick for verifying infrastructure compliance. Additionally, it includes references to various test cases and metrics for assessing NFVI performance.

3. NFV infrastructure
Questions
• Does the NFV infrastructure fulfil the basic VNF type requirements?
• Is the NFV infrastructure under test suitable for the target VNF application?
3
The golden rule: find as many faults/bottlenecks as early as possible, using
simple test case or combinations of test cases.

4. Pre-deployment validation of NFVI

• Use simple test cases or test suite to verify
the infrastructure compliance to VNF
requirements.
• Used for judging if the target VNF is capable
of running on a NFV infrastructure.
• Provide a chance to find any potential
hardware fault, system limit or bottleneck at
an earlier stage.
