The Spring Festival will be here in a few days. The annual Spring Festival travel rush is about to begin, and train stations and airports are already bustling with people. To say which airport is the most beautiful, it is undoubtedly Beijing Daxing International Airport, which was put into operation just a few months ago. Its dreamlike design attracted countless eyeballs. In fact, the saying "If you want to get rich, build roads first" that people often say when they go home for the New Year has already been extended to the field of civil aviation.
It is reported that the civil air traffic control system guaranteed 34.58 million flight takeoffs and landings during the "Twelfth Five-Year Plan", an increase of 64.9% over the "Eleventh Five-Year Plan" and an average annual growth of 10.03%; the "Thirteenth Five-Year Plan" still maintains With rapid growth, the contradiction between air traffic demand and the relatively tight supply capacity of the airspace system has become increasingly prominent. The construction of Daxing International Airport is a typical example, not only to relieve the air traffic pressure in the capital, but also to promote the economy of southern Beijing and the coordinated development of Beijing, Tianjin and Hebei.
However, for everyone who takes a plane, 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 systems. How can aviation information systems better improve efficiency? Rice Information and Huawei solved the mystery for us.
Anyone who knows something about civil aviation knows that safety is the foundation of the civil aviation industry. Because of this, under some severe weather conditions, the delay rate of civil aviation will greatly increase. But the question is, if the weather is calm throughout the route, can it be done on time?
The answer is yes. In fact, people who fly frequently recently will find that the delay rate has been very low. This is because flying in the winter without large-scale snowfall is much safer than flying in the rainy season in the summer. In the past, on the basis of security, the efficiency of information systems was the top priority.
Nowadays, the civil aviation system has proposed the "four strong air traffic control" strategy of "strong safety, strong efficiency, strong intelligence, and strong coordination". Among them, "strong intelligence" and "strong coordination" are obviously very important for various civil aviation systems. Integrated analysis of data poses new challenges.
It is reported that relevant civil aviation units hope to rationally and flexibly apply various traffic management strategies through continuous monitoring, analysis and negotiation by building the "industry brain" of air traffic flow management - the national flow management system. and measures to improve the operational efficiency of relevant civil aviation units in collaboration with airlines, airports and other related operating units and reduce delays.
The so-called "industry brain" is actually a new smart decision-making tool. The purpose is to ask today's civil aviation information system to fully and effectively utilize air and ground resources and optimize the operation of the system while ensuring safety. Achieve capacity and flow balance.
Previously, the information infrastructure of the civil aviation system mainly came from several global industry giants, such as Airbus and Thales. But now, as the technical capabilities and product quality of domestic manufacturers have been effectively improved, civil aviation systems have begun to consider more domestic equipment at the hardware level.
In terms of informatization, Civil Aviation Systems has long-term cooperation with Nanjing Laisi Information Technology Co., Ltd., a professional information system integrator and service provider under China Electronics Technology Group. In the past many years of civil aviation project implementation, Les Information has not only accumulated rich experience, but also has always adhered to the concept of innovation. It is this development idea that has led Civil Aviation Systems and Rice Information to focus on Huawei, which is the leader in domestic data infrastructure and storage equipment.
As we all know, Huawei started out as a manufacturer of carrier equipment, extending from carrier-grade products downwards, so the 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 for data.
In fact, under 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 kind of data call is the reading and writing of data on the storage device at the infrastructure level. The more frequently the database is called, the higher the performance requirements for the underlying storage device.
It is reported that for the civil aviation national traffic management system, the collection, sorting, and storage of a series of operational data such as flight plans, surveillance, environment, meteorology, static capacity, and flow control measures in traffic management need to be logically A unified traffic management operation database is formed on the network, which is error-free, so that relevant business analysis can be carried out to support the efficient operation of various business subsystems.
In fact, the core database that supports the national traffic management system supports the operation of each business system. With so many flights across the country, data is bound to be generated all the time, so there will be a large IO throughput. Although the data traffic is relatively stable, the calculation, reading and writing frequency is high, and there is no room for error. In other words, the national traffic management system has two main technical requirements for underlying storage: one is performance, and the other is high availability.
It is worth mentioning that Huawei's storage equipment has been outstanding in the domestic market in recent years, far surpassing other brands, indicating that the advantages of Huawei's storage are very obvious at least in the domestic market.
It is reported that through years of accumulation in flash memory technology, Huawei's independently developed HSSD supports hot-swapping of SAS and NVMe dual interfaces. It does not require a SAS controller or SAS Expander and is directly connected to the CPU through the PCIe bus. Effectively improve the performance, reliability and scalability of the system.
According to the relevant person in charge of Rice Information, the database performance test results of this civil aviation project show that under the development environment, the air traffic flow system maintains more than 943 database sessions while smoothly accessing the database during operation. , embodying the value of OceanStor Dorado performance and high availability.
It is worth mentioning that Huawei has also added artificial intelligence technology to OceanStor Dorado all-flash storage. Through multiple types of smart chips and FlashLink smart algorithms, coupled with a full range of end-to-end NVMe architecture, The overall stable storage latency is reduced to less than 1ms, and the read latency even reaches the shortest 80 μs in the industry. This is because the smart chip carries a considerable part of the load of the general-purpose CPU and can accelerate front-end access performance by 20%, for example, shortening the report statistics time by 1/3.
It should be said that fast and stable is not only China Civil Aviation’s commitment to every passenger, but also a requirement for civil aviation information systems, traffic management systems and underlying storage systems.
We know that today in the era of big data, data exchanges between storage devices and computing devices are extremely frequent. At the same time, storage devices need to ensure efficient data transmission, while security and recoverability are equally important.
In fact, OceanStor Dorado's RAID technology uses Huawei's patented algorithm and can support multiple RAID types at the same time. RAID-TP can tolerate three disk failures, thus providing higher availability.
To ensure the high reliability of data, Huawei and Rice Information once had some thoughts on the choice of dual-active or active-standby databases. After detailed demonstrations and multiple rounds of comprehensive testing, both parties finally agreed that Huawei's storage-based active-active solution is not only more efficient and has lower operation and maintenance costs, but can also ensure that core services remain online and carry high-efficiency and high-reliability traffic management. In terms of database operation, it is not inferior to any foreign established products.
It is reported that after rigorous and careful evaluation, Rice Information and Huawei stood out in the extremely competitive bidding process.
After a period of test operation, the system has maintained stable operation and has further won a reputation in the civil aviation industry. Today, in the process of building an "industry brain" for air traffic flow management, Rice Information and Huawei continue to cooperate in depth to optimize system performance.
We know that Huawei regards itself as a "black land" to provide infrastructure services, while partners like Rice Information can focus more on the development of industry business-related solutions and customer service.
The person in charge of Rice Information said: "We all know that Huawei has excellent technical strength. Through nearly two years of cooperation, we have not only experienced the performance, multi-center disaster recovery and intelligence of Huawei's storage equipment, but Our technical strength in operations and maintenance and other aspects, and we also realize the benefits of cooperation with Huawei, which gives us more confidence to meet the new challenges of data integration and analysis of various civil aviation systems.”
Satisfy customers and make us happy. Partners benefit, which is Huawei's core concept in building an industry ecosystem.
As we usher in a new historical moment in 2020 and the 2020s, perhaps the "industry brain" of civil aviation traffic flow management that brings reliability guarantee to air traffic travel is the key to our success in the new era. The new basis for getting rich in the era of “If you want to get rich, build roads first”. The progress of information technology is the guarantee for the sustainable development of thousands of industries today, isn't it?
