Liu Yanjie: The existing network can not meet the needs of vehicle networking

At the 2014 China Future Network Development and Innovation Forum and the Global SDN Open Network Summit, academician Liu Yanjie of China Academy of Engineering said that the Internet is gradually penetrating into the real economy from the traditional "consumption" field. The new network forms such as industrial Internet, energy Internet and vehicle networking are emerging, but the traditional internet is difficult to meet the demand of real economy in the aspect of service quality guarantee. Liu Yanjie called on China to seize the future research and planning in the field of network, and actively explore new technical framework to meet the needs of Internet development.

Liu Yanjie that the Internet is an inevitable trend in the field of information consumption and e-commerce to the productive entity economy. GE's "Industrial Internet" and Germany's "Industrial 4.0" concept will bring great commercial value to the real economy. However, the current Internet architecture faces a series of challenges in terms of reliability, real-time, service level and mass data processing.

In the field of intelligent transportation, domestic telecom operators and SAIC, FAW, Changan, Chery, BYD, Geely and other strategic cooperation has been signed, and other domestic and foreign auto companies are also in cooperation to negotiate. However, the new business requirements emerging in the field of intelligent transportation, such as to solve the problem of avoidance, vehicle lane control, safety-assisted driving and so on, generally require network transmission delay below 50 milliseconds, some applications require 10 milliseconds, or even 3 milliseconds, traditional network technology can not overcome network latency problem. Liu Yanjie called on China to seize the future research and planning in the field of network, and actively explore new Internet technology framework to meet the needs of a variety of emerging business development.

It is understood that Google, Microsoft, at&t, IBM and other global mainstream operators and equipment manufacturers in the future network, the United States and Japan, the European Union and other countries in recent years has launched a series of national future network test facilities projects. Based on the SCN (Service customization Network) architecture, China's first future network test net has now covered 26 cities nationwide, realizing the interconnection of the relevant test networks in the United States and the European Union. The 80 teams in China also carried out experimental verification for this framework.

Liu Yanjie, a "pretend to be a geek", said that the so-called SCN service custom network, simple to understand is the user needs what kind of network services, can customize what kind of network. The SCN will build a network system with service quality assurance, and the operators can construct a new industrial ecosystem based on the differentiated needs of users. Liu Yanjie admits that our SCN framework needs a process to go international and expand its application in the international arena. Because of the current countries in the future network construction has a lot of input, international standards of competition will become more and more intense. At present, the Future Network Innovation Research Institute of Jiangsu, Open Network Foundation (ONF) and the next Generation Internet Engineering Center have begun to cooperate in the future of network experience sharing, international standard setting, product cooperation, research and development resource sharing, test network construction and so on.
