Intel Zhang Xu: the integration of communication and computing will be the key to 5g
with the proposal and Prospect of ITU and domestic and foreign 5g vision and demand, and the research on 5g key technologies of industrial chain acceleration, it can be seen that 5g will gradually develop towards software defined network and virtualization based on a variety of physical layer and network layer technologies. At the same time, how to integrate diverse technologies to serve business will be the key to 5g development
in this regard, Zhang Xu, director of Intel, pointed out that in addition to the revolutionary transformation of the traditional physical layer and network layer technology, the future 5g development will have a more far-reaching impact on the integration of communication and computing
To avoid affecting the measurement accuracy of the equipmentEdge computing will play a role in improving user experience
there is no doubt that 5g will put more emphasis on user experience, so what new experience will 5g bring to users? In other words, what disruptive applications will appear in 5g
in Zhang Xu's view, the business in 5g era is actually very difficult to predict
looking at the development of mobile communication, compared with the evolution of technology, the development of business is often more unpredictable, which is not only affected by the degree of development of the sample as a disk, but also by various factors. For example, from 2G to 3G, if there is no opportunity for apple, users may not experience the benefits of high-speed network so soon, and a large number of mobile terminal applications may not emerge so soon. From 3G to 4G, the business development is also unpredictable. At the beginning of 4G research, for example, HD video was predicted to be the killer application of 4G, but in fact, a small number of users watch video through 4G networks. Instead, various social networking applications have become the mainstream. The same is true for 5g applications in the future. It remains to be seen whether the currently predicted emerging businesses such as virtual reality and augmented reality will become 5g's killer businesses
Zhang Xu believes that although the types of services cannot be accurately predicted, it is certain that in the 5g era, the end-to-end delay will be smaller, which is an important guarantee for users to achieve a good business experience. In Zhang Xu's view, whether it is personal applications such as virtual reality and augmented reality, or industrial applications such as industrial control, reaction time is crucial. He first cited Google glasses as an example. When using Google glasses, the terminal immediately displays real-time relevant information in front of the user through search and calculation for the objects concerned by the user, so as to achieve the effect of augmented reality, which requires a relatively short reaction time. If a large number of calculations need to be uploaded to the remote server for completion, and the calculation results are returned to the user, the user's eyes have long been removed. Another example is holding concerts or ball games. In such scenarios, users are very dense. Many users are downloading data while uploading data, but all traffic is centered on local content. In this case, if the data is uploaded to the remote server and then downloaded from this server, it is also a great burden for the core
there are many scenarios like this. If we simply rely on improving network performance and reducing delay, it is difficult to meet the requirements of future services. Zhang Xu believes that edge computing will be an important way to solve this problem, which is why edge computing has become a hot spot in recent years. Zhang Xu pointed out that in the future 5g application scenarios, many application scenarios have put forward requirements for edge computing, such as vehicle communication, virtual reality and augmented reality, which need to deploy computing power closer to users rather than relying on cloud servers
support network slicing through sdn/nfv to achieve rapid network customization
Zhang Xu pointed out that the requirements for operators in the 5g era are also more complex. In addition to traditional broadband mobile applications, M2M applications and vertical industry applications also need to be supported. Transparent pipelines will not meet the requirements of 5g. If the previous smart pipeline was icing on the cake for operators, with the increasing pressure of operating costs and network expansion, intelligence and customization will become necessary to meet the needs of different applications and industries
on the one hand, for operators, users' needs will be more diverse and dynamic, and at the same time, they need to meet the different needs of different users and businesses for the network. Some need large bandwidth, and some need low delay. Operators first need to identify different needs in order to provide users with satisfactory services
on the other hand, operators have to face the challenge of sustainable operation. Unrestricted use of resources is naturally the simplest way to maximize the satisfaction of users. However, in practice, while meeting the needs of businesses and users, operators also need to consider the issue of operating costs. Operators need to deploy computing resources more effectively and make full use of the resources of the whole network. Therefore, from the perspective of operators, networks must be intelligent, and intelligent introduces the standard background and content of GB 8624 (2) 012, which shows the computing power of networks and customization of networks. How to realize the dynamic allocation of network resources has become a key consideration for operators, which is why SDN and nfv technologies have received widespread attention. Its purpose is to reduce the cost of operation and maintenance and provide customization capabilities
the whole industry chain promotes the development of terminals
for ordinary users, the changes of wireless communication are first reflected in terminals. Zhang Xu pointed out that terminals in the future not only need to meet the requirements of low power consumption and diversification, but also need stronger computing power and lower processing delay
The requirement of5g is not only for the network, but also for the terminal and the cloud. When the 5g network can be connected, whether the cloud can process hundreds of millions of users at the same time, and whether the terminal processing time can be guaranteed, that is, from the terminal to the network, from the cloud, from hardware, software to communication, users can enjoy the real 5g experience. This is a whole chain development. Zhang Xu said that, for example, the most commonly used tcp/ip end-to-end protocol stack provides a better compromise between performance and stability under the conditions of wired network and low-speed network, but it is not suitable for the network with low delay and high bandwidth in the future, and needs further improvement
the current computing capacity of the terminal can not handle the data volume under the high bandwidth in the future, while meeting the requirements of low delay. 5g is not only the improvement of communication rate, but also the close connection between communication and computing to truly meet the needs of users and reflect to the terminal, which requires stronger integration ability, computing ability and real-time response ability. Therefore, for terminals, chip design, OS, software design, and the combination with networks need to be developed
