In a few days, the Spring Festival is coming, and the annual Spring Festival travel rush craze is about to begin. The train station and the airport are already buzzing. To say which airport is the most beautiful, it is undoubtedly the Beijing Daxing International Airport, which was just put into operation a few months ago. Its fantastic design attracted countless eyes for a time. In fact, the phrase "If you want to be rich, build roads first" that you often say when you go home for the New Year has already extended to the civil aviation field.
It is reported that the "Twelfth Five-Year Plan" civil aviation air traffic control system guaranteed 34.58 million flights, an increase of 64.9% over the "Eleventh Five-Year Plan", with an average annual increase of10.03%; The "Thirteenth Five-Year Plan" still maintained rapid growth, and the contradiction between air traffic demand and relatively tight airspace system supply capacity became increasingly prominent. The construction of Daxing International Airport is a typical example, which can not only alleviate the air traffic pressure in the capital, but also promote the coordinated economic development of southern Beijing and Beijing-Tianjin-Hebei.
But for everyone who flies, how to shorten the waiting time and how to avoid flight delays must be the focus of attention. Behind these demands is the upgrade of civil aviation information system. How to improve the efficiency of aviation information system? Mi Information and Huawei solved the puzzle for us.
Anyone who knows something about civil aviation knows that safety is the foundation of the civil aviation industry. Because of this, in some bad weather conditions, the delay rate of civil aviation will be greatly improved. But the question is, if the weather of the whole route is quiet, can it still be on time?
The answer is yes. In fact, people who often fly recently will find that the proportion of delays is already very low, because flying in winter without large-scale snowfall is much safer than flying in rainy summer. In the past, on the basis of security, the efficiency of information system was the most important.
Nowadays, the civil aviation system has put forward the "Four Strong Air Traffic Control" strategy of "strong security, strong efficiency, strong wisdom and strong coordination", in which "strong wisdom" and "strong coordination" obviously pose new challenges to the integration and analysis of civil aviation system data.
It is reported that relevant civil aviation units hope to build the "industry brain" of air traffic flow management-the national flow management system, and use various flow management strategies and measures reasonably and flexibly through continuous monitoring, analysis and consultation, so as to improve the operational efficiency of cooperation between relevant civil aviation units and airlines, airports and other related operating units and reduce delays.
The so-called "industry brain" is actually a new type of intelligent decision-making tool. The purpose is to ask today's civil aviation information system how to make full and effective use of air and ground resources and optimize the balance of capacity and flow under the premise of ensuring safety.
Previously, the information infrastructure of civil aviation system mainly came from several global industry giants, such as Airbus and Terez. But nowadays, with the technical ability and product quality of domestic manufacturers being effectively improved, the civil aviation system has begun to consider more domestic equipment at the hardware level.
In terms of informatization, the civil aviation system has long cooperated with Nanjing Rice Information Technology Co., Ltd., a professional information system integrator and service provider under China Electronics Technology Group. In the implementation of civil aviation projects in the past few years, Mi Information has not only accumulated rich experience, but also adhered to the innovative concept. It is this development idea that makes the civil aviation system and rice information focus on Huawei, the leader of domestic data infrastructure and storage equipment.
As we all know, Huawei started as an operator's equipment and extended from telecom-grade products, so its quality can naturally be guaranteed. In the IT product line, the closest thing to the database is storage. In other words, storage is the infrastructure of data.
In fact, below the application system is the core database, and each application system calls the data in the core database to support the operation of each business system. This data call is to read and write the data on the storage device at the infrastructure level. The more frequently the database is called, the higher the performance requirements of the underlying storage devices.
It is reported that for the national traffic management system of civil aviation, it is necessary to logically form a unified traffic management operation database to collect, sort out and store a series of operation data such as flight plan, monitoring, environment, meteorology, static capacity and flow control measures in traffic management, so as to carry out relevant business analysis and support the efficient operation of various business subsystems.
In fact, the core database supporting the national traffic management system supports the operation of various business systems. So many flights in the country will inevitably produce data all the time, so it will produce a great IO throughput-although the data traffic is relatively stable, the frequency of calculation, reading and writing is very high, and there is no room for any mistakes. In other words, the national traffic management system mainly has two technical requirements for the lower storage: one is performance, and the other is high availability.
It is worth mentioning that in recent years, Huawei storage equipment stands out in the domestic market, far exceeding other brands, indicating that the advantages of Huawei storage are obvious at least in the domestic market.
It is reported that through years of accumulation in flash memory technology, the HSSD independently developed by Huawei supports dual-interface hot plug of SAS and NVMe, and is directly connected to CPU through PCIe bus, without the need for SAS controller and SAS expander, which effectively improves the performance, reliability and scalability of the system.
According to the person in charge of Mi Information, the database performance test results of this civil aviation project show that in the development environment, the air traffic flow system keeps more than 943 database sessions while accessing the database smoothly, which reflects the performance and high availability value of OceanStor Dorado.
It is worth mentioning that Huawei has also added artificial intelligence technology to OceanStor Dorado all-flash storage. Through multi-type intelligent chips and FlashLink intelligent algorithm, and all-round end-to-end NVMe architecture, the overall storage stability delay is reduced to below 1 ms, and the reading delay even reaches the shortest 80 μs in the whole industry. This is because the smart chip carries a considerable part of the load of the general CPU, which can accelerate the front-end access performance by 20%, for example, shorten the time of report statistics by 1/3.
It should be said that speed and stability are not only the promise of China Civil Aviation to every passenger, but also the requirements of civil aviation information system, traffic management system and bottom storage system.
We know that in today's era of big data, data exchange between storage devices and computing devices is extremely frequent. At the same time, although storage devices need to ensure efficient data transmission, security and recoverability are equally important.
In fact, OceanStor Dorado's RAID technology adopts Huawei's patented algorithm, which can support multiple RAID types at the same time, among which RAID-TP can tolerate three disk failures, thus providing higher availability.
In order to ensure the high reliability of data, Huawei and Mi Information have thought about the choice of active database and active database. After detailed argumentation and multiple rounds of all-round testing, both parties finally agreed that Huawei's storage-based dual-active solution not only has higher efficiency and lower operation and maintenance costs, but also can ensure that the core business is continuously online, and the database operation is not lost to any foreign established products, with efficient and reliable traffic management.
It is reported that after a rigorous and meticulous review, the cooperation between Mi Information and Huawei stood out in the extremely competitive bidding process.
After a period of testing and operation, the system runs stably and has won a good reputation in the civil aviation industry. Nowadays, in the process of building the "industry brain" of air traffic flow management, Mi Information and Huawei continue to cooperate deeply to optimize system performance.
We know that Huawei regards itself as a "black land" and provides infrastructure services, while partners such as Mi Information can focus more on solution development and customer service related to industry and commerce.
The person in charge of Mi Information said: "We all know that Huawei's technical strength is excellent. Through the cooperation in the past two years, we not only realized the technical strength of Huawei's storage equipment in terms of performance, multi-center disaster recovery, intelligent operation and maintenance, but also realized the benefits of cooperation with Huawei, which made us more confident to cope with the new challenges of data integration and analysis of civil aviation systems. "
Satisfying customers and benefiting partners is the core concept of Huawei to build an industry ecosystem.
As we usher in the new historical moment of 2020 and 265438+ 1920, perhaps the "industry brain" of civil aviation air traffic flow management to ensure the reliability of air traffic travel is the new foundation for us to get rich in the new era. The progress of information technology is the guarantee for the sustainable development of thousands of industries in Qian Qian today, isn't it?
