Jiang Ming, deputy director of the Network Technology Research Institute of China Telecom Co., LTD., said that Gigabit optical network as a new network infrastructure can effectively help the construction of new industrialization. The Industrial Internet Industry Alliance has included industrial PON as a core technology solution in a number of series of white papers, and the industrial PON application cases and scenarios in the “Guanghua Cup” Gigabit optical network Application Innovation Competition are becoming more and more abundant, and the Gigabit optical network enabling thousands of lines have reached a consensus.

The broad concept of industrial PON is customized network PON, for education, enterprises, transportation, hotel, medical, manufacturing, energy and other industries, using PON technology as a network base to achieve full service. With three network characteristics: a network to the end, production, office, security, wireless and other full coverage; A network bearing, data, voice, video, surveillance and other full bearing; One network integration, data acquisition, AI, edge computing and other technologies integration.

AR-08AE-14293 Jiang Ming introduced that China Telecom has carried out the research and development and practice of industrial PON since 2017, by constantly promoting the evolution and upgrading of industrial PON technology, creating a factory network fusion optical base, realizing data interconnection, providing edge computing functions, docking with the cloud platform to build an industrial data intelligence center, generating cloud based on the network, Ewan generating wisdom, and empowering with wisdom.

Based on industrial PON capabilities,

Innovative industrial control network architecture

Jiang Ming said that based on years of practice, China Telecom has proposed a new industrial control network integration innovation architecture based on industrial PON for the first time for the upgrading and evolution of industrial manufacturing networks, and built a deterministic link capability, intelligent management capability, computing and network integration capability, and high availability network security capability to meet the new trend of intelligent and digital development of industrial sites.

According to reports, the entire network architecture is characterized by autonomy and control, open and universal, with the following six key technologies.

Key technology 1: universal, standardized network protocols and technologies. Industrial PON adheres to the ITU-T standard PON protocol to realize industrial ecological reuse and meet key requirements such as large bandwidth, low delay and high reliability. PON network slicing technology supports the diversified and converged bearing of multiple services in industrial scenarios, improving the adaptation capability of industrial control scenarios.

Key technology 2: High availability network assurance. In addition to the PON network’s own optical link protection protocol, there are multiple types of protection forms such as dual OLT handhold Type D, which match the protection configuration of industrial networks, can achieve on-demand redundancy networking, system reliability up to 99.999%, and provide highly reliable data transmission for industrial production networks.

Key technology 3: Industrial PON safety technology. Through the construction of a “four-fold protection of the whole life cycle” security system, the goal of “defense in depth” of network equipment, “controllable and available” of industrial networks, “impregnable” of sensitive data, and “knowable and perceptible” of security events is achieved.

AR-08AE-14293 Key Technology 4: Intention-driven industrial PON deterministic capability. The deterministic technology system of industrial PON system proposed by China Telecom provides guarantee for control deterministic services in industrial field networks and “reaches the international advanced level”. At the same time, it realizes the demand perception of industrial control business flow and the deterministic scheduling of global PON network automation for industrial control business needs.

Key technology 5: intelligent management ability. Based on SDN and distributed acquisition technology, standardized model abstraction for PON devices and business logic is carried out to meet customers’ intelligent operation and maintenance requirements, realize rapid deployment and orchestration of new services, and support sub-second situational awareness and real-time panoramic view of PON network.

Key technology 6: high performance computer network control integration. Industrial PON network integrates computing power to solve the problem of edge side computing and network isolation, and covers edge application scenarios through computing power expansion, enhances the integration of control and network, and easily realizes cross-level data exchange and application collaboration.
