 Hello, my name is Karlsund Rosenüvel. I am co-founder and CTO of EA NTC, the European Advanced Networking Test Centre. We are an independent test lab for telecommunications solutions based in Berlin in Germany, and we're very proud to be present here at the OpenStack Summit in Barcelona, showcasing three demos of our NFV interoperability and performance tests. So on the side here, you can see the different areas that we keep ourselves busy with regarding NFV, telco cloud testing at this time. We're looking at interoperability and we're looking at performance in two different scenarios. So let me start with the interoperability. The industry has established a lot of ecosystems already, so they are usually vendor-based or based around open source solutions. Now, after all, service providers want to select in the end from any kind of solutions independent of the ecosystem. So our job is really to test the interoperability between the NFV infrastructure and the virtualized network functions and the management orchestration solutions across the whole industry. We do this initiative called the new IP agency, that's a non-for-profit association, and members are testing with us already for more than a year the interoperability of NFVIs to VNFs. We're creating more programs as we go. Currently we keep ourselves busy with VNF manager interoperability and in January next year we're going to collaborate with Etsy on a plug test that they will run on management orchestration interoperability. So far regarding interrupt testing, now the other question is how do we prove, validate and help the industry progress the performance of NFV solutions? After all, the business cases will only work if the solutions actually perform and are efficient per node. Now, we partner with Intel Network Builders program in this case. Intel Network Builders sends us specific vendor solutions and we test them for performance. This is a very individual program, so we've tested Adva Ensemble, which is a v-switch, just a packet forwarding solution on an atom platform. We tested Meta-Switches parameter session border controller, that's a policy management and voice over IP session border controller solution. And we tested recently Sandvines traffic steering engine, that's a virtualized load balancer. So all of these solutions are very diverse and we have to evaluate them, not only from the bottom up throughput latency, the basics, but we really have to look at the application use cases, how our service provider is going to use them. The key in doing realistic and to end performance tests is really to look at the use cases from the application point of view. In the same way we do this in more custom vendor tests that we conduct at ENTC, lately with Cisco and Juniper, before with other vendors such as Nokia as well. One of the live demos we're showing here is Juniper's STNFV orchestration for a cloud CPE solution, where Juniper provided an orchestrator that would actually not only control the data center, but also control the end to end STN path as well. So there is lots more to do, there are many activities that we're running, so stay tuned for more tests to be published. The interesting fact here is that all of these solutions in the industry that we've tested so far are based on OpenStack, so that's an interesting and very encouraging commonality. So with that, thank you very much for your attention, thank you.
