IP network encounters dilemma, multi-modal smart network is the future development direction

  Industry Watch

  "In the era of the Internet of Everything, it is increasingly difficult for IP networks to meet the needs for service quality in diversified scenarios. Multi-modal Smart Network (PINet) represents the future development direction of network technology and industry." Recently, Academician of the Chinese Academy of Engineering Wu Jiangxing said in an interview with a reporter from Science and Technology Daily.

  It is understood that the network was originally born from basic data services. Due to the limitations of the technology, the TCP/IP protocol that has been developed so far is still based on end-to-end transmission to provide services, and only supports a single IP addressing mode... The qualitative technical characteristics have led to endless network development problems in terms of performance and security.

  In order to solve the bottleneck problem of network development and adapt to the current network application needs of the digital economy era, Wu Jiangxing led the scientific research team to propose a multi-modal intelligent network (PINet). It adopts multi-modal addressing routing technology, embeds new addressing and routing functional elements in the network architecture, and supports the coexistence and collaboration of multi-modal identification such as IP, content identification, identity identification, and geospatial identification. Can greatly enrich the diversity of cyberspace.

The new generation of network services is transforming to system structure innovation

  As the "highway" of digital information, the Internet is taking on more and more tasks in the current society, with more diverse terminal types and continuous development of access methods, such as human-human, human-machine, machine-machine, network-network communication, etc. Becoming the norm, this requires the network to provide diversified, intelligent, efficient and stable services for massive businesses.

  Wu Jiangxing believes that cyberspace must first resolve basic cyber issues. With the slowdown of Moore's Law, the growth of computing power brought about by hardware equipment upgrades has declined, and the gap between computing data and computing power has become larger and larger. The new generation of network services is shifting from relying mainly on technological progress to mainly relying on system structure innovation.

  At present, many new network technology research results have emerged around the world, such as cloud, reconfigurable network, software-defined network, and network function virtualization. But today’s situation is "pearls all over the floor but not a necklace." Therefore, new network technologies urgently need to beaded into chains to build a diversified network environment.

  The multi-modal smart network using multi-modal addressing routing technology builds a real network platform with a considerable scale, and develops applications in smart cities, industrial control networks, scientific experiments, etc., and innovates network architecture systems to make the network functional form It can flexibly and efficiently adapt to the complex and changeable social development needs, making the problems of "high latency", "high cost" and "difficult to control" in traditional networks a history.

Multi-modal intelligent network has "three magic weapons"

  In addition to multi-modal addressing routing technology, Wu Jiangxing said that the core technology of multi-modal intelligent network enabling new infrastructure has "three magic weapons", namely, the network is fully definable, intelligent network management and control, and the network endogenous security structure.

  The first is the network full-dimensional definable technology. Emerging network service forms are emerging in an endless stream, constantly posing new challenges to the carrying capacity of the underlying network equipment, while the traditional network infrastructure is single and functionally closed, and hardware equipment is usually unable to be updated and upgraded in time, resulting in a long-term gap between network service capabilities and application business requirements There is a "generation gap" problem. The full-dimensional definable technology creates a completely transparent basic platform to realize the all-round opening of network element equipment, protocol control, network resources, node capabilities, network interfaces, forwarding control, and load-bearing methods. It is for the development of new network architecture research, testing and The application provides the basic environment.

  The second is network intelligent control technology. Wu Jiangxing emphasized that after the introduction of artificial intelligence technology, an integrated intelligent network management and control mechanism of “perception, decision-making, and adaptation” can be established, and the entire network can be managed and optimized through the intelligent management and control of local nodes in the network. To intelligent perception, autonomous decision-making and automatic execution.

  The third is network endogenous security construction technology. Currently, new Internet security threats such as link and node failures and system vulnerabilities are emerging in endlessly. Network endogenous security construction technology builds a new mimic defense technology based on the concept of "structure determines security" and "system is greater than the sum of parts". Any "detection" or "trial and error" attack may change the current defense scenario and break The periodic effect of unknown threats on the network improves the overall security of cyberspace.
