How to do a pre-deployment NFVI validation quickly and

efficientlyJing Lu, Huawei technologies Co., LTD

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.

Pre-deployment validation of NFVI

4

• 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.
