 Hello, I'd like to do a product update for Black and Coldplay. My name is Dima, I'm from Huawei Telecom. American.com, so he asked me to do it. What's Black and Coldplay? First of all, probably not familiar, it's a SDN controller for Neutron. We tried our best to have an approach that is lightweight, distributed and keep the Coldplay's really small. And we do it with open switch and open fold and we try to rely on any databases you might want, by keeping it blackboard and distributed. That's about it, like one sentence about being full. We started in Kylo, we have about 20 contributors in the last release, mainly from Huawei and Fibrom. We are a small project. In Pyke we did quite a lot, actually, with our small come out hands. We are trying to finish a lot of MBMs to have the support for Kubernetes and other containers more easily by having several networks in Singapore. We also tried to merge service function training. It's an implementation of the API defined by network in SFC, a separate project. We will support MBMs for the first part. It's mainly done and we will try to bring ganassage in the next phase of the future. We did the makeover of our existing network services like security groups and port security for to support IPv6. We added another cloud services like table discovery to support the food to add more support for IPv6 tenants. We started working on non-merging widget build, the dynamic routing. The core base right now is also an implementation of a neutral and non-cranly product. We added a support for Casano database for our northbound backup to finish our Ansible deployment labels also in this release. So we need to close Ansible right now. First thing that we did is port security, QS, the port QS. We implemented the GCP marking that first came with the applications. We implemented distributed SNAP. It's a lesson model that allows you to go out of your computer directly without going to the network. No, I think in DVR it's basically a switch computer to be in its own network node in the sense of being able to support SNAP. We also did some major heavy lifting inside our cloud base to make the addition of new services much easier. For the driver, just Twin Park will be done for you. We have some nice specs about this. Next thing we want to do for QAINs, we always want to implement more network services, so we are looking to implement LBUS V2, and for us and any other network services, but in one of the Japanese suggestions we are happy to hear. We are exploring currently to support not just OpenWizWizWiz, and it's like iPod on the IPPF. It's not something we have a very clear idea about, but we think that we can get as well. We think of integrating other agent types like OpenWizWiz agent, so we can have both Dragonflow and OpenWizWiz agent deploy at the same environment in case you want to try us out or to roll in migration. We'll bring it on when you want to start working on a VM-level quality of service which aggregates all the traffic of 1VM and just one port. We're doing a bunch of stuff, but that's the main thing that we're going to do for QAIN. That's about my list. We want to see in practice what my mission is to deploy us, whether it's packaging or features that we need that we should have. We're also looking for more developers and contributors to help us review and design and implement all those open-breads. Sorry, I will answer that. So we... Sorry, can you repeat the question? Yeah, I will repeat the question. The question was, did we have some scalability testing for the Dragonflow? And the answer is we have. We've done scalability on the control plane for our Dragonflow as it is a control... as the controller. We've done the benchmarking that was actually presented in Barcelona. We had help from StratoAG who were gracious to contribute 40 servers on their cloud and we've actually done benchmark for 4,000 Dragonflow controllers. The test was to try and run Dragonflow to distribute and to implement the updates for the integration, sub-integration, port-creation, and deletion. We called first a single controller on each server, so we had about 36 of them. And we used Redis as the database with three charts, each chart had the replication, so six Redis. And after we getting this baseline, the performance was about three ports a second and we didn't try to optimize that was maybe a performance of a neutral and arm setup and not a great control. But we just wanted to see how that gets changed when we go from 36 controllers to 4,000 controllers. And we were very surprised to learn it just didn't affect all the others. So we get the same exact performance for 4,000 controllers. So, I think it's difficult. Yeah, so we didn't try more than 4,000 because we ran out of hardware and we will actually do that if we get more machines or someone wants to test that. Obviously, to run on Dragonflow and not Dragonflow access and not to make a subscriber, so it should be pretty easy to migrate to the tool. Well, we have this blueprint on allowing Dragonflow and other type of agents to work together. So, we hope that you can deploy just, I don't know, 10% of your machines as Dragonflow and then see how it goes and have this rolling upgrade working. Is that something that needs to be done in Dragonflow version or can it be done? Currently in the process of doing it, can I use the fighting version of Dragonflow to rely on anything specific in the neutral code base or is that just a release? I think you might run into some trouble. I haven't tested it myself. I think it's something. The compatibility or this interoperability should be very vague? I don't think it will be vague but I hope it will be vague.
