Seasons alternate, fluctuating hot and cold, and it is often the season of frequent colds. Especially in the alternation of autumn and winter seasons, it is even more chilly, every piece of warm clothes will be on the court, and autumn clothes and long pants will all appear. In addition to enriching the "equipment", medicines to prevent colds, as well as humidifiers, skin care and lip care cosmetics, are all indispensable.

But from a scientific point of view, the most important thing to prevent colds and health problems of changing seasons is to learn to match different clothes according to different climates, look! sky! gas! Pre! report! - is the most important!

With the development of meteorological science, the ability of human weather forecasting has been significantly improved. For example, next year, the Beijing Meteorological Bureau will release the warning information of sudden and severe weather such as rainstorm and lightning more than 1 hour in advance, the accuracy rate of 24-hour rainstorm forecast is not less than 65%, and the meteorological service guarantee capacity for major events will reach the international advanced level. ! With the 24-hour accurate weather forecast updated from time to time, people can plan their clothes, arrange travel reasonably, and avoid the harm of bad weather to themselves, not to mention the cold!

The rapid development of meteorological forecasting not only requires the support of basic sciences such as aerodynamics, dynamic meteorology, and climatology, and branch disciplines such as radar meteorology and satellite meteorology. The advancement of meteorological science and technology also relies on cloud, big data, and virtualization. Assisted by ICT technology.

The Beijing Meteorological Bureau makes full use of advanced cloud technology to build basic business resources, uses virtualization technology and distributed technology to build virtualized resource pools, supports business needs for network resources, computing resources and storage resources, and provides its own meteorological informatization and intelligence. Provide strong foundation support.

At the same time, they also fully learned from the past experience that the network has become a bottleneck in the entire business operation, and believed that the reliability, flexibility, and transparent monitoring of the network have become urgent issues that need to be solved in the operation and maintenance of the entire ICT system. Because the construction of the basic network system and the security level protection system directly affects the reliability, security and availability of the entire meteorological business system. It has become an inevitable necessity to re-plan and construct the basic network system and security-level protection system from an overall perspective, and to coordinate and integrate the existing network system.

At the same time, the Beijing Meteorological Bureau is also responsible for the 2022 Beijing Winter Olympics meteorological service guarantee project. The basic network needs to carry a variety of key services such as the refined smart weather service system, the refined smart weather forecast system, and the early warning information release system. For high-frequency and high-quality business operations, only a large-bandwidth, ultra-stable, high-reliability, high-security, and programmable basic network can meet the needs of meteorological modernization services and lay a solid foundation for the meteorological guarantee of the Winter Olympics.

Huawei is honored to assist the Beijing Meteorological Bureau in the construction of a new network and to support the weather service guarantee for the Winter Olympics. Through Huawei CloudEngine 12800 series high-end data center switches, a new generation of high-performance, high-density, high-latency CloudEngine 6800 series data center switches, as well as T-class next-generation firewall USG9560 and next-generation AI firewall USG6000E and other products, an early warning center of Beijing Meteorological Administration will be built. Set up a core exchange area, connect the early warning center data center network, audio and video network, management network, office network, government extranet, external network, Internet, national early warning information release center, and district early warning information release centers, and realize the boundaries of each region isolation. In the data center network, SDN is used to build a large two-layer network structure, which connects hardware devices such as servers and distributed storage to resource pools to achieve 40G aggregation and 10G interconnection switching capabilities, and meet the requirements of big data mining analysis and business system interaction in the next three to five years. For the needs of the network, it can fully cope with a large number of weather forecasts and real-time event guarantees during the future Winter Olympics. In addition, in the office network (floor access), Huawei uses security protection measures to isolate and protect it independently from other areas to improve the security of the office network and meet the design requirements of Class III.

During the network construction of the early warning center of the Beijing Meteorological Bureau, Huawei has always regarded information security as one of the important links in the network construction process. The protection levels of communication security, computing and host security, application and data security, and physical environment security meet the national information system security level protection requirements.

The new basic network system and security level protection system have greatly improved the technical level and business capabilities of the basic network of the Beijing Meteorological Bureau. It will not only carry all the meteorological services of the Beijing Meteorological Bureau, such as high-performance computing, climate services, weather forecast services, and office services. business, and will also carry the Winter Olympics meteorological service guarantee project. In the future, during the preparations for the 2022 Winter Olympics and the Winter Paralympics and during the competition, Huawei's IP network will help the Winter Olympics Meteorological Center to collect and analyze relevant weather service requirements, compile and implement weather service plans, and undertake various weather support services. Warm and considerate, let the Winter Olympics be cold and not "cold".

No longer afraid of fluctuating hot and cold, no longer being defeated by unexpected cold currents, we have advanced networks to support advanced meteorological technology and connect T-level atmospheric data. Advance forecast, real-time calibration, dress warmly, and travel reasonably, all because we have the weather forecast!
