On July 31, 2022, the 2022 China (Ningbo) New Infrastructure and Digital Economy Summit Forum was successfully held. Sun Telecom was invited to participate in this forum. This forum aims to further promote the exchange and connection of related enterprises, technical forces and industrial resources in the field of digital new infrastructure.
The new infrastructure uses new generation information technologies such as Mobile Internet, 5G, Internet of Things, Big Data, Cloud Computing and AI to promote the process of digital economy comprehensively. Entering the era of new infrastructure, enterprises need to build their own optical network environment first. Through the Space-earth integrated communication network and Cloud-Network Integration to help the development of the digital economy.
Space-Earth Integrated Communication Network
New infrastructure requires strong and stable communication network support. Comprehensively upgrade the communication network infrastructure, form a high-speed ubiquitous, interconnected, and integrated communication network support system, and promote cloud-network collaboration and computing-network integration.
Space-earth integrated communication network integrates the satellite network with the traditional terrestrial optical fiber network, and consists of a space-based backbone network, a space-based access network, and a ground-based node network. Data relay satellites operating in GEO orbit, “Pigeon”, “Iridium”, OneWeb, Hongyan Project, etc. Put the processing, switching, network control and other functions on the star to complete. Global seamless coverage is achieved through the interconnection of satellite-to-ground optical links, and the system can operate independently of ground nodes.
The space segment integrates all kinds of owned and leased GEO and orbital communication satellites and manages them in a unified manner, thereby providing resource guarantees for various users in land, sea, air and space. The satellite resource pool uses L, S, C, Ku, Ka and other spectrum resources, the scale can be adjusted according to needs, and provides mobile or broadband services through the ground coverage of multi-point beam antennas. The ground segment consists of infrastructures such as hub ports and earth stations, as well as core networks, IT systems, and edge clouds. Upgrade the existing earth station to form the ability to connect the sky, the earth, and the cloud network, and realize the interconnection and interoperability of heterogeneous networks.
“All-optical networks (AON) technology allows data to be transmitted without any electrical processing, which can result in farther transmission distances. AON technology is used in Telecom Network, FTTH, Data Center, Cloud Computing and Internet of Things (IoT), etc.” As the fiber optic solutions provider Sun Telecom said, the all-optical network will evolve from a bandwidth-driven pipeline network to an experience-driven cloud-based network, and needs to have five characteristics of the deterministic bearer, full-service access, network flattening, operation and maintenance automation, and cloud-optic integration. Based on the quality of rigid pipelines Connectivity, consolidate the bearing base of the digital economy.
The Cloud-Network integration is the core driver and essential connotation of new infrastructure, and the digital base of new infrastructure. Through the high-speed interconnection between different resource pools of the same cloud service provider, the differences in business relationships caused by different distribution regions of user cloud hosts in practical applications can be resolved to ensure network stability and transmission security. Or high-speed interconnection between public cloud resource pools between different cloud service providers, breaking through the resource barriers of different manufacturers, and realizing the interconnection of cross-cloud service providers and cross-cloud resource pools.
Optical fiber networks, 5G and other network infrastructure have become the infrastructure that is as important to the national economy and people’s livelihood as water and electricity. The new infrastructure is inseparable from the infrastructure of the optical fiber network. Only by steadily laying the foundation for the network, building a communication network that integrates the sky and the earth, and implementing the integration of the cloud and the network, can we move into the new infrastructure era, meet the needs of computing power development, and promote the development of the digital economy.
