ETSI announced Wednesday that its two-week NFV Plugtests interoperability event that took place from 23 January to 3 February in Spain yielded a whopping 98% success rate – at least for specific features.

For features such as network service on-boarding, instantiation and termination, 98% of the interoperability tests succeeded. For more complex operations like scaling and network service updates, very encouraging initial results were observed. The test plan, overall results and lessons learnt during the Plugtests are fed back to ETSI NFV ISG.

“The results for the setup and termination groups were near perfect, achieving almost 100% success for both”, says Pierre Lynch, vice chairman of the NFV Testing, Implementation and Open Source working group. “The results for the three other groups, while encouraging, showed that there is still work to be done on those areas. But this is to be expected, since the scale operations are quite complex, and the specifications have not been completed yet. Receiving feedback on the Stage 2 specifications is valuable for the ETSI NFV ISG as they are currently working on data modelling and can take those into account.”

ETSI said 35 commercial and open source implementations were tested for interoperability, including 15 virtual network functions, nine management and orchestration solutions, and 11 NFV platforms. More than 160 engineers were involved in the preparation of the Plugtests, 80 of them on-site, coming from a diverse community of NFV implementers, including vendors and key Open Source projects such as ETSI OSM, Open Baton, OPEN-O and OPNFV.

During the two week intense testing phase, test sessions were organized in several parallel tracks, ensuring that all participants had at least one test session scheduled any time and that a maximum number of combinations could be tested. Each day ten different combinations of management and orchestration (MANO) and VIM&NFVI (NFV platform) were scheduled, with up to four virtualized network functions (VNFs), to be tested on each of them during the day.

Overall, 160 different combinations of VNF, MANO and VIM&NFVI were tested for interoperability and over 1500 individual test results were reported.

The test plan developed by ETSI’s Center for Testing and Interoperability, focused on validating ETSI NFV Release 2 end-to-end capabilities including management of descriptors and software images, as well as life cycle management of network services and virtual network functions. It consisted of 26 test cases, classified in several groups going from onboarding and instantiation, through different types of scaling and network service updates to terminate and teardown operations.
