 I'm really excited to be here today at the SD1 Summit Paris 2019 with the Cisco team as well as the Riedel Networks team. Michael and Joachim, hi guys. Can you tell us a little bit more which conclusions you've made from speaking to all the companies present here today as well as the service providers? One thing I noticed is that there are so many manufacturers and as well there are many overlay network service providers, but there are not so many managed network service providers like us for example, right? So there is there's many overlay network but less underlay network and less transport network service providers which is probably of the interest of certain enterprise customers as far as we believe in it. Joachim, would you agree? Yes, principally you have three types of companies here. These are the classical carriers, Zingtail, Korea Telecom, us as an example. The manufacturers of course Huawei, Juniper, Cisco of course and of course over the top the overlay network providers. The system integrators who sell services on top of the SD1 solutions and add value to or hope to add value to the customer. Thank you and just to understand in your opinion where do you see SD1 going in the next upcoming years? Maybe what you see here and I think the SD1 summit is a start here is that SD1 is a commodity. It's a clear must for the underlying network to manage the network to manage all the different types of access and over the top there are the applications and there's the future probably. So whether it's one acceleration whether it's firewall security in a total and I think services we do not know yet about whether it's related with SDN with all the network virtualization functions which we do not have yet and I think the market is also not yet ready but will come in the future much much more than we see today. It's funny though that the industry is already talking about the future right but today probably four to ten percent of the overall networking market is suffered if I then whereby all the other things are more traditional transport networks right and that might change in the next five years from ten ninety to ninety ten but the future will tell us we're not a wisdom teller sorry.
