Industry Solutions
National railway transportation is a major infrastructure related to national economy and people's livelihood. China has always attached importance to the development of railway transportation. In recent years, the country has continued to increase investment in the railway industry, especially in high-speed railways, emphasized the importance of the development of high-speed railways and urban rail transit, and put forward clear goals for railway construction. During the "Eleventh Five-Year Plan" period, China's investment in railways reached 1.56 trillion yuan. With the deepening of national strategies and development layouts such as "Medium and Long-Term Railway Network Planning", "Transportation Power", "High Speed Rail Going Out", "The Belt and Road" and "New Infrastructure", exploring the transport capacity of existing railway infrastructure has become the main work of railway construction, and informatization has played a more and more important role.
The National Railway Administration is responsible for the unified scheduling and command of railway transportation, arranging the allocation of railway network capacity resources, and playing an important role in China's railway transportation tasks. The state-owned railway group has 18 railway bureaus. The information system of the railway mainly includes passenger service system, integrated dispatching system (operation dispatching system) and disaster prevention and safety monitoring system. The intelligent route selection of data center export links, the stable operation of key core application systems (passenger ticket system, dispatching system), and the intelligent scheduling of multiple data centers are issues that customers are most concerned about.
The SuperAD application delivery product of Hongji provides fast, safe, highly available and flexible intelligent solutions for railway industry customers. The SuperAD L4-L7 server load function can solve the problem of stable operation of key core application systems (passenger ticket system, dispatching system) through rich health check methods and load balancing algorithms. Secondly, SuperAD can achieve flexible scheduling between multiple data centers through intelligent DNS analysis. Users can choose appropriate data centers for access and visit. In addition, the SuperAD application delivery product can also achieve linkage between server load balancing and global load balancing, so that users can visit more stable and fast. The SuperAD application delivery product has a throughput performance of 1G-200G, which can meet the requirements of railway customers for large-scale traffic and high concurrency scenarios.
The system adopts multi-core technology, which greatly improves the processing performance of the SuperAD series application delivery devices. At the same time, the product uses a dedicated super parallel processing architecture, which greatly improves the processing performance of L4-L7 and meets users' current and future expansion needs.
The product fully supports virtualization technology, including device virtualization and virtualization operating systems such as Vmware and KVM. Through the pAPI and eRule interfaces provided by the system, it works well with OpenFlow and SDN to smoothly integrate ADC into the SDN network.
The product integrates multiple functions into one: it can achieve local server load balancing, link load balancing, and also implement global load balancing for multiple data centers. For some special and complex functional requirements, the system supports programmable script eRule, which can deeply customize user needs, which is difficult for many load balancing devices to achieve. These functions provide the device with high cost performance.
The system supports a rich load balancing function for L3-L7 application servers. Through deep analysis of application protocols, it can provide comprehensive application load balancing and content exchange capabilities. It also has a comprehensive application health check mechanism to timely diagnose servers or applications that are abnormal. The system has a cluster mode of primary-backup and multi-device groups to ensure the stability and continuity of enterprise applications.
The system can adopt encryption methods such as HTTPS and SSH for network management, avoiding the security risks caused by direct access to devices in plain text communication. The system also incorporates DDoS attack protection functionality. It can provide SSL decryption and encryption, and integrated with CA and client certificates to formulate flexible policies based on certificate identity for access and authorization.
