 Ladies and gentlemen, dear friends, I'm Xiao Dong from China Mobile. I'm so glad and very happy to present at the open-infra-love keynote to share our efforts on building China Mobile's digital infrastructure and engagement with open-source communities. The title of my speech is Connection plus Computing plus Capacity opens a new era of digital infrastructure. As a first, I will do share some progress of China Mobile. Currently, China Mobile has built the world's largest telecom network with over 5 million base stations, including 516,000 5G base stations, serving as one-fifth of the world's population. We have 950 million biologists. Our IoT connection is more than 160 million. With a total number of our collections in over 2 billion. As a leading operator, China Mobile already impressed open-source for many years. Our open-source strategy covers network authorization, network authorization, cloud-based radio access network, automated integration, connectivity, and many more. As a major contributor, we have already actively participated in many open-source projects in telecom communities such as OpenNFV, ONAP, O-RUN, AnuQuate, Acrena, XCvilla, S6, and so on. Now, I will focus on China Mobile's participation in the OpenNFV community. We won a CPSA award in the year 2016. And during these years, we have fully rolled out the open-source architectures into China Mobile's digital infrastructures and achieved 5.9-carry grid availability. Currently, China Mobile has three clouds. A natural cloud for 4G and 5G. A public cloud for public service. And an IT cloud for internal service. All of them running on OpenStack. Nearly a quarter of the global number. Meanwhile, as a good member of OpenNFV foundation, China Mobile actively contributions to the community, including more than 30 best practices with more than 10 engineers, such as SPC members and PTRs, and multiple code contributions in various projects. China Mobile is continuously driven innovations from CT to ICT, and now to DOI CT, which means the convergence of DT, OT, IT, and CT. In the future, China Mobile is planning to build production-class computing-class capability digital infrastructures with 5G, B5G, 6G, and 7, which means computing-source network, and ability as a server platform. We regard standardization and open-source as two different forces for the telecom innovation. Now, let's focus on the two important areas which is more important for industry from my view. The first one is the 16 network, which is a very big issue for industry. China Mobile released a white paper on the vision of the network architecture of the 16, in which we called the architecture is distributed on two more six network architectures. We envisioned 20 potential key technologies, including the Airspace Ground Network, the Data Wind Network, and so on, which has been released on the slides. We welcome open-source computing to pick closer attention to the 16 root maps and set up new open-source projects of the area such as the program Rainbow Networks, the Data Wind Network Modelings, and the white box open hardware, and open characters, and so on. The second one is CFN, which we call it Computing Force Network. It is a very big new pair of plans and visions for China Mobile and many operators. It is computer-centric with network services and foundations and deep integration of many key components and technologies, such as network, cloud, big data, AI, security, edge, terminal, and blockchain. We call it ABCD Next, the four key words for the integrated and unified stories. As shown on the slides, we have already built a CFN technology network. We would like to invite all of you and other open-source communities to join us and contribute. Currently, some of the key technologies in CFN has been supported by the open-source project, including eight computers, connecting, heterogeneous computing, completion of load, and computing meeting. But, from my view, the other areas to prototype are not yet rebuilt or integrated, such as the unified operation for computing network works, and in-network computing, and so on. And last, I think time is limited. I want to make a brief introduction. A new era of innovation is upon us along with the first course of the digital economy. The convergence of the DOICT opens a big innovation for all of us. China Mobile recently announced a connection-plus-open-plus-computing-force-plus-capability strategy, and has launched the 6G and the CFN projects. We formally expect open-source to be the main driving force for this innovation. And in this area, such as computing-force-routine, DTN, data-to-network, diversity-computing, abstraction, many innovations expect. We are expecting the open-source community to support. And second for your attention, China Mobile looks forward to work with the community to actively promote open-source and accelerate industry openness and collaborations, which you all enjoy the rest of the open-e-front networking notes, and wish all of you can see China in the future. Thank you.
