In the post-covid-19 era, the acceleration of smart city mobility by "new infrastructure" will boost smart cities into the fourth wave of development, characterized by ICT technologies that will penetrate deep into the core business transformation areas of cities, with the result that more and more cities will undergo digital transformation. Urban intelligent body is about to come out, urban intelligent body contains 4 main parts: intelligent application, intelligent hub, intelligent connection, intelligent interaction, for the important part of the intelligent connection part - F5G all-optical connection, just like the physical city in the water network, power grid, transportation network, gas network, F5G all-optical network is the infrastructure of the digital city, is the base of urban digitalization.
<h1 class="pgc-h-arrow-right" data-track="2" > the development of e-government networks to build four key value propositions</h1>
The digital base of the urban intelligent body is built with the F5G all-optical network to support the basic operation of the entire city, which can be built from four value points.
First, co-ordination. The traditional e-government network is a chimney structure, each commission has a private network, including a private network and transmission lines, these private networks bring duplication of construction and waste of resources, there are also difficulties in communication, information is not shared and other issues. Taking a medium-sized city as an example, the survey found that there are more than 70 government networks in this city. Based on the principle of overall planning, based on the bearing of a network to coordinate, to plan, to intensive construction, to share resources, it will inevitably rely on the bottom of the urban optical network base. This base connects the various commissions and offices, sinks the street office community, and reaches the application level, integrating the originally scattered multiple private networks into a network to achieve the integration of the number of private networks from N to 1. Overall planning and construction can reduce the construction and operating costs of urban infrastructure networks, and at the same time bring about an improvement in efficiency. The survey found that through overall planning and construction, the operating costs of urban networks can be reduced by 30% and the efficiency can be increased by 40%.
Second, security. F5G brings together upstream and downstream manufacturers, operators, design institutes and standards organizations, etc., and China has the ability of the whole industry chain from optical fiber, devices, equipment to applications, and is also far ahead in terms of industrial standards and patents. In terms of business bearing, the use of frequency division multiplexing methods to physically distinguish the business of each commissioning bureau; the use of time-division multiplexing, the use of time-division multiplexing, the same commissioning bureau of different departments of the business for physical differentiation, the use of these hard pipeline technology to build a city-exclusive unified network, for the development of the city to provide a safe and stable connection base.
Third, green. From the perspective of the entire network development process, carbon emissions need to be based on three "revolutions". The first revolution was the media revolution, which used more energy-efficient information and communication media, that is, replacing network cables with optical fibers. The main material of optical fiber is silicon, silicon is widely abundant in nature, resources are inexhaustible, unlike copper and other non-ferrous metals, resources are limited. In terms of architectural revolution, the traditional campus network is a three-layer architecture, with core layer, aggregation layer and access layer. The all-optical network replaces the network equipment of the aggregation layer with the unconnected optical device, reducing the computer room space by 90% and the cable resource by 80%, reducing carbon emissions by 60%. In the recycling revolution, the service life of optical fiber is 30 years, which can reduce carbon emissions by 75% relative to the entire life cycle of copper wire. Experiments by the German Ministry of Environment and Nature Conservation have shown that by playing high-definition video, fiber-optic-based FTTH technology, the carbon emission of video playback per hour is only 2 grams, while copper wire is 4 grams. Based on this conclusion, more investment should be made to expand the fiber optic network.
Fourth, be efficient. Urban all-optical network is the basis of wireless, IP and other networks, is the basic base of urban cloud and applications, using all-optical connection, high-quality and efficient service of various applications, cloud services, to achieve data interconnection, so that "one network communication office" more convenient, so that "one network unified management" more efficient.
<h1 class="pgc-h-arrow-right" data-track="25" > the advantages of radio and television to help the construction of e-government networks</h1>
To coordinate the construction of an e-government network, two basic conditions are required: optical fiber resources and a professional operation and maintenance team. Radio and Television has the licenses of "Internet Domestic Data Transmission Service" and "Domestic Communication Facilities Service Business", and Radio and Television has sufficient urban optical fiber resources and a professional operation and maintenance team, which can effectively help the government solve the problems of network fiber source and operation and maintenance after network construction is completed. Taking the Guizhou radio and television network as an example, the radio and television optical fiber network realizes the whole network at the provincial, municipal, county, township and village levels, and implements the integration of government, civil and commercial innovative formats such as smart policing, smart education, smart tourism, smart medical care, smart city, and digital village on a large scale, and has rich experience in operation and maintenance.
Through the survey, it was found that radio and television, as an excellent full-service comprehensive service provider in China, has four major advantages:
First of all, strong resource capabilities: computer rooms and optical fiber resources can achieve full regional coverage, which can provide fast network access services for government customers;
Secondly, rich experience in operation and maintenance: Radio and Television has a professional and skilled, flexible and efficient maintenance team, and has accumulated rich experience in operation and maintenance in many years of practice;
Third, rich business platform capabilities and strong technical strength: Radio and Television relies on the advantages of publicity outlets and builds related platforms to provide a variety of business services for government customers;
Finally, rich project delivery and government business maintenance capabilities: Radio and Television has a deep understanding of the network construction requirements of the government, enterprises and institutions, and has undertaken a number of large-scale private network construction, and has rich delivery and operation and maintenance capabilities.
Through the construction of F5G all-optical base through radio and television, the following changes can be brought to the e-government network:
First, security improvements. Abandoning the traditional e-government network using the method of renting a naked optical fiber direct connection or renting bandwidth, a unique private network to carry the e-government network, and the "National E-government Network Technology and Operation Management Specifications" require the e-government network to use a dedicated transmission network, the use of hard isolation technology to build the transmission backbone of the e-government network to match the specification requirements, the use of time-division multiplexing and frequency division multiplexing to physically isolate each service, to ensure the security of service transmission;
Second, scalability is improved. Relying on this F5G all-optical network of radio and television, it realizes that the service jumps into the cloud and brings a deterministic ultra-low latency experience; service expansion only needs to expand the corresponding resources on this private network to support the fast service on-line;
Third, the efficiency of O&M has been improved. Dedicated to the private network, it can operate and maintain from the perspective of the entire network, and the network operation and maintenance, fault demarcation, resource coordination, etc. can be considered uniformly; using OTDR+GIS technology, it can actively manage optical fiber resources, actively identify potential threats to services, and change passive operation and maintenance to active operation and maintenance;
Fourth, the utilization rate of resources has increased. The originally scattered multi-private network is integrated into a private network, and the business is unified planning, which brings about the improvement of resource efficiency and the reduction of operating costs.
Shanghai has won the heavyweight Global Smart City Award and has become a pioneer in the development of smart cities. Shanghai has achieved such outstanding results, which is inseparable from the blessing of the F5G all-light base. Relying on the F5G all-optical network built by Oriental Cable, shanghai e-government network is unified into a network, which covers 16 districts, 22 units and 33 thematic applications in the city, realizing "one screen view of Shanghai, one network management of the whole city, cross-level linkage". As a government service brand in Shanghai, "One Netcom Office" has been online for more than a year, and has accessed more than 2,000 service items, the number of personal real-name users has exceeded 20 million, and citizens and enterprises have become more and more "as convenient as online shopping". At present, Shanghai's "One Netcom Office" has greatly reduced the working time, greatly reduced the number of work materials, and greatly improved the praise rate, which has effectively enhanced the sense of gain of citizens and enterprises.
