Enabling technologies for edge computing
The enabling technologies of edge computing mainly include three aspects: cloud and virtualization, large-capacity servers, and enabling application and service ecosystems.
1) Cloud and virtualization. The separation of hardware and software and the implementation of cloud-based solutions have changed the IT industry in the past 10 years. This transformation enables the success of APPs, software platforms and underlying hardware resources through the use of regulatory processes Ground decoupling. On a platform, we can deploy multiple virtual machines and let them share hardware resources in a controlled and flexible way. Cloud solutions take advantage of these technologies to provide computing and storage resources on demand. More flexibility in network and service deployment. Currently, cloud and virtualization technologies have been utilized by telecom cloud and network function virtualization (NFV). They are changing the way the communications industry has transformed the IT industry in the past 10 years. It is also a key technology for edge computing.
2) Large-capacity server. In a large sense, it refers to the hardware level. Since edge computing moves centralized cloud computing to the edge of the network, the dependence of edge computing on server performance cannot be ignored. High-capacity IT hardware can promote the commercial success of edge computing. For example, large-capacity servers cover almost every aspect involving computer components, such as large-capacity storage (the transition from TB-level mechanical hard drives to solid-state drives), multi-core central processing units (central processing unit, CPU), graphics processing unit (GPU), 10Gbps/100Gbps switches, etc., these can ensure efficient and stable work of the server, because the amount of data at the edge of the network can reach ZB level in the future. The hardware requirements for the server are very large. Edge computing gateway
3) Enable the application and service ecosystem. If cloud and virtualization technologies and dependence on server performance are hard requirements for edge computing, then to make the entire edge computing industry chain more prosperous, software and application supply are needed Businesses develop and introduce market innovation and breakthrough services and applications. After all, edge computing is just a user-oriented platform deployed at the edge of the network. The realization of any function is inseparable from the openness of APP and the deployment of innovative services. Use open standards and APIs, along with familiar programming models, associated tool chains and software development kits, are key pillars that encourage and accelerate the development of new cutting-edge applications or the adaptation of existing applications.
Deployment of edge computing servers
Currently, edge computing servers are independent devices. The white paper briefly gives edge computing deployment suggestions, as shown in Figure 1. The MEC server as a separate device can be deployed in long term evolution (LTE) base stations. On the side, it can be deployed at the cell site (can be 3G or LTE), or at the radio network controller (RNC). The location is very flexible. If you want to decide the specific location of the MEC server deployment, you also need to It is decided according to the specific business type and business scenario.
At present, edge computing has excellent development prospects. Domestic and foreign operators, Internet giants, equipment vendors and chip manufacturers have all deployed the edge computing industry. Multiple edge computing industry alliances are constantly being established, and operators are restructuring base stations and central computer rooms to adapt to In the edge computing business, IT and Internet giants have promoted the edge computing industry and launched various intelligent products for edge computing. Many companies, including China Unicom, also place their hopes on edge computing and strengthen cooperation with Internet companies. It will kick off the digital reform and accelerate China Unicom’s mixed-ownership reform in a more in-depth direction. The content of future edge computing standardization must focus on the standardization of network architecture to adapt to the needs of various business capabilities of edge computing; on the other hand, it must also It is necessary to pay more attention to the integration with specific emerging businesses and expand the influence of edge computing, including Internet of Vehicles, industrial Internet, artificial intelligence, etc. China Unicom will also continue to pay attention to and actively participate in various edge computing standardization efforts and expand edge computing pilot projects. scale, gradually carry out computer room reconstruction work, strengthen cooperation, and jointly create an edge computing industry ecosystem.
