Industry Solutions
With the popularity of multiple operators in China approaching saturation, the incremental market has become a saturated one, and the entire operator communication system has become increasingly complex, such as complex customer personalization, scene diversity, etc. Faced with the complexity of the system, the traditional architecture formed in the past and the solution based on this architecture are increasingly difficult to adapt to various complex requirements. At the same time, as a key basic service provider, operators carry the entire Internet's most basic and core data interaction and transmission, and the importance of connecting business systems and network complexity exceeds that of general enterprise networks. Moreover, operators' external business systems often access millions of users. Therefore, the security and reliability of their business systems are crucial.
Cloud computing has become a key weapon for the three major telecom operators to respond to the ICT convergence trend and avoid becoming a pipeline service provider. Each operator invests heavily in cloud computing, from the construction of large-scale data centers at the lowest level to the cloud resource management platform at the upper level, to many service forms such as cloud-based hosting, cloud storage, and elastic computing that directly face their own businesses and third-party users. By assigning dedicated computing resources to different business applications, hardware servers are managed as resource pools to build a flexible architecture, convenient management, efficient data centers.
Operators have numerous internal and external business systems with huge data volumes, requiring non-stop services for 7 x 24 hours. How to achieve high reliability of data center multi-live support and business systems is a challenge that operators must face when building network systems. At the same time, operators' networks must achieve 99.999% stability, and equipment must also meet high-performance, high-expansion, high-stability, power redundancy, hard disk redundancy and other telecom-grade features to fully guarantee the reliable delivery of core business systems.
With the comprehensive popularization of intelligent terminals and online applications, the era of big data has arrived. In this rapidly growing network with huge data volumes, no matter how good the existing infrastructure network links are, there will be many problems such as critical application downtime and slow access speeds. How to improve the performance of operators' applications in cloud architectures and ensure high availability of application systems is also a major issue facing operators' cloud environments.
Hongji technology has always been committed to continuously adding more intelligent features to the network to provide advanced application flexibility for enterprises to maintain a leading position. Hongji's application delivery products can provide a variety of leading server performance optimization technologies, security protection measures, application acceleration and other functions while significantly reducing operating costs. They can successfully provide critical business applications with the best flexibility to fully meet their business needs.
In the scenario where multiple data centers have multiple exit links, two Hongji SuperAD devices are deployed at each data center exit link to achieve bidirectional load balancing of data center exit links. Through intelligent DNS technology of global load balancing, user access is intelligently resolved, guiding users to access nearby data centers and intelligent distribution between data centers to ensure that user requests arrive at data centers through optimal paths, avoiding single link failure at exits and data center failures. Hongji SuperAD devices deployed in the intranet support HTTP, SIP and other application protocols to achieve 4-7 layer load balancing for core business systems such as operators' BOSS systems, CRM systems, call center systems, billing systems, etc., ensuring high reliability and availability of application access.
The Hongji VirtualAD series application delivery product is designed to adapt to the current development of data centers, the current network status, and the rapid growth of application requirements. The system adopts the latest multi-core multi-processor technology and provides high-performance 4-7 layer application processing capabilities. The unique SPOS operating system not only provides high performance but also has rich 7-layer features and flexible health check functions to ensure the availability and reliability of applications. The VirtualAD product series can run on VMware, KVM, and Hyper-V platforms, demonstrating excellent performance and stability.
The flexible eRule advanced script technology and custom health check scripts can more accurately detect packet content for unparalleled flexibility in managing application traffic in the network. The system supports various application optimization techniques, including caching, compression, connection reuse, and SSL offloading, combined with wide area network load balancing and link load balancing to maximize users' access experiences.
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.
