China’s 5g has officially entered the stage of large-scale commercial, and the business scenario with large demand for edge side connection ushers in a new opportunity of vigorous development. In this trend, the demand for edge enabling drives the capacity of cloud computing to sink, and distributed cloud has become a new trend in the evolution of computing architecture. As the integration hub of 5g and distributed cloud, MEC edge cloud technology architecture is gradually clear, attracting all parties in the industry to speed up the deployment. The integration of 5g and distributed cloud is accelerating the edge enabling “new infrastructure” and effectively helping the digital transformation of traditional industries.
5g era, multi vertical industry ushers in a new opportunity for vigorous development
As a new engine to drive the development of digital economy, 5g has become a strategic highland for the development of various countries. 2019 is regarded as the first year of global 5g business. The United States, South Korea and other major countries in the world have accelerated the process of 5g business, and China’s basic telecom enterprises have been awarded 5g licenses. In 2020, three basic telecom operators will speed up the construction of 5g network, and China’s 5g network will officially enter the stage of large-scale commercial deployment.
5g technology promotes the cross generation upgrading of edge side connection capability, and the pace of vertical industry application is gradually accelerated. Compared with 4G mobile communication technology, 5g can achieve greater bandwidth, wider connection and lower delay. Specifically, 5g user experience rate can reach 100mbit / s to 1GBIT / s, base station connection density can reach 1 million per square kilometer, and transmission delay can reach millisecond level.
At the same time, 5g network integrates it technology, and effectively improves the transmission quality and management ability of differentiated services through flexible network slicing technology. With the large-scale commercial deployment of 5g, industrial Internet, digital media and other industries have gradually carried out commercial deployment in 5g integration, and smart medical, Internet of vehicles, smart city, digital agriculture and other fields have also explored and practiced in 5g application.
Distributed cloud emerges as the times require and becomes an important force of “new infrastructure”
The edge enabling demand drives cloud computing capacity to sink, and distributed cloud has become a new trend of computing architecture evolution. The massive edge connection scenarios generated by 5g era drive cloud computing to a more global distributed combination mode. Distributed cloud or distributed cloud computing is a new mode of cloud computing from single data center deployment to multi data center deployment in different physical locations, and from centralized architecture to distributed architecture expansion, which plays an important role in supporting the wide application of 5g, Internet of things and other technologies. According to the different deployment location, the size of infrastructure, the strength of service capacity and other factors, distributed cloud generally includes three business forms: Center cloud, regional cloud and edge cloud.
The distributed cloud accelerates the construction around the cloud edge, and becomes an important force under the tide of “new infrastructure”. Various types of manufacturers, including telecom operators, Internet cloud service providers and so on, have tried to sink the central cloud function to the edge of the network through edge cloud services, edge node management platform and other cloud edge collaborative products. How to get through the channel between the center cloud and the edge cloud, strengthen the management ability of the center cloud on the service and application of the edge cloud, and realize more intelligent and secure cloud edge resource collaboration is the core of the current distributed cloud construction.
Under the wave of “new infrastructure”, distributed cloud will run through the communication network infrastructure, new technology infrastructure and computing infrastructure, and support the traditional fields such as industry, agriculture, transportation and energy to build integrated infrastructure, which will gradually play an important role.
MEC edge cloud is the integration hub of 5g and distributed cloud
As the integration hub of 5g and distributed cloud, MEC edge cloud relies on CT network elements such as UPF and it resources such as computing and storage. Cloud computing technology is used to further software and modularize network functions, and it virtual resources are deployed to achieve lightweight and real-time computing power. Compared with traditional cloud computing, MEC edge cloud emphasizes the combination of connectivity and computing power, including a complete architecture covering the resource layer, virtualization layer, platform layer and application layer, and emphasizes the unique capabilities of local streaming, network capacity opening and network resource management.
The new model of distributed cloud urges telecom operators to take the lead in accelerating the edge side layout. China Telecom relies on its own advantages to form a “2 + 4 + 31 + X” distributed cloud resource layout; China Unicom will complete MEC layout construction in all provinces and key cities by the end of 2020; China Mobile has carried out MEC edge cloud application pilot in more than 20 places in 10 provinces. At present, the trend of construction is to build MEC edge room on the edge side of 5g network closer to users, or to use the existing edge room for transformation to increase the number of MEC edge cloud nodes. The key deployment sites are generally in vehicle, factory, port, indoor, building, hospital, park and other application scenarios.
5g + distributed cloud improves user experience in digital media industry
Relevant surveys show that at present, more than 70% of the fragmented time of China’s intelligent end users is “consumed”. In the entertainment applications represented by live video, short video and games, the digital entertainment industry has entered the explosive growth stage. In the face of surging user traffic and increasingly fierce market competition, the digital media industry explores to rely on emerging technologies to achieve business model innovation and improve user experience.
5g + distributed cloud can help the video industry cope with massive users and surging traffic. Data shows that video users in China are the first user group in the whole network. In order to meet the needs of high definition and fluency under high concurrent and large traffic, major cloud service providers have launched video cloud products based on distributed cloud, providing end-to-end solutions for the video industry through the product SDK, edge nodes all over the country and strong cloud edge collaboration capability. In the future, as 5g is gradually commercialized, a new generation of video experience such as 4K video and VR live broadcast will enter the daily life of the public.
5g + distributed cloud can promote the game industry to create a new upgrade experience. On the one hand, through distributed cloud, the game picture rendering can be placed on the user’s edge side to reduce the discomfort caused by high delay and low refresh rate, and realize the complete AR and VR game experience; On the other hand, for large-scale multiplayer online games, players in the same area can connect through the same edge node nearby, effectively reducing the interaction delay.
5g + distributed cloud accelerates the digitization process in traditional fields
In industrial, production and other application scenarios, the real-time processing of massive data collected by terminal devices, model training, data mining and analysis and other requirements put forward high requirements for computing and collaborative scheduling capabilities of edge side and cloud. The distributed cloud mode supported by 5g network fully combines the advantages of edge computing and cloud computing, and becomes the mainstream mode to accelerate the digital process of industry, agriculture and other industries.
In the industrial manufacturing scene, the intelligent factory platform based on distributed cloud gives computing power to the edge nodes of the industrial scene, which is convenient for timely detection of anomalies, and achieves predictive maintenance of production equipment through centralized data analysis of the central cloud. In the future, with the characteristics of high speed, low delay and high reliability of 5g network, cloud side collaboration in data, resources, applications, security, operation and maintenance can be realized more efficiently. Managers can operate field devices more quickly and accurately through the central cloud, and further realize intelligent operation management and digital production.
In the livestock breeding scenario, the edge gateway deployed on the farm side can receive the data uploaded from the sensors worn by pigs, cattle, sheep and other livestock, and coordinate the data to the central cloud after real-time processing, so as to analyze and master the livestock distribution, feed consumption, epidemic data, etc. in the first time. In the future, taking the “express train” of 5g network can further solve the problems of incomplete network coverage and difficult access to large-scale equipment faced by intelligent animal husbandry, ensure the timeliness and accuracy of livestock information collection, and realize networked, digital and intelligent breeding.
With the accelerated large-scale deployment of 5g and the wave of “new infrastructure”, the integration of 5g and distributed cloud has a good development environment. At this stage, we should focus on core technologies and application scenarios to make continuous breakthroughs. On the one hand, it is suggested that all parties in the industry focus on the key technologies such as cloud edge collaboration, heterogeneous computing and distributed reasoning to enhance the maturity of core technologies; On the other hand, we should start from the edge enabling effect, promote the practical experience in the fields of digital media and production, and constantly explore the deployment and application mode of 5g + distributed cloud in typical business scenarios.
In a word, the accelerated integration of 5g and distributed cloud will provide a solid infrastructure for the digital era where everything is interconnected and computing is ubiquitous, which is worthy of the unremitting efforts of all parties in the industry!
