It includes basic functions and high availability capabilities. This document aims to standardize products and solutions. It focuses on global accelerator services. The goal is to improve services from providers. It also helps users choose appropriate services. Global Accelerator (GA) is a network acceleration service. It relies on high-quality BGP bandwidth to function. It uses global transmission network to achieve global network access. This service can reduce the impact of network problems. These problems include latency, jitter, and packet loss. The goal is to maintain service quality. GA instances optimize TCP, HTTP, and HTTPS connections. They can terminate TCP sessions nearby and uninstall SSL. This further enhances the acceleration effect. 2 Basic functions 2.1Overview This indicator is defined as the functions of nearby access and connection networking. 2.2Acceleration area coverage Covering major cities in China and at least 2 overseas regions. 2.3Networking Supports connectivity between public cloud acceleration area and origin server. 2.4Network acceleration 1)Supports connectivity between public cloud acceleration area and origin server; 2)Supports protocol acceleration for various transmission modes; 3)Supports routing strategies that dynamically detect line quality.; 3 High availability capabilities 3.1 Overview This metric defines the disaster recovery capability. 3.2 Intelligent DNS resolution 1)Assign an IP address to the nearest one via domain name resolution; 2)Different IPs are assigned for same domain name in varied regions; 3)Supports manual or automatic switching of nearby IP addresses. 3.3 Redundant link mechanism 1) Traffic automatically switches to redundant lines if one line fails. 2) Configure and modify related routes. 3) Redundant nodes or links are automatically switched. 3.4 Load on the origin server Origin server load mechanism is supported: 1)Configure and modify the load area of the origin server. 2)It can switch to the load area during network faults for service. 3.5 Health check mechanism 1)Supports Layer 4 and Layer 7 health checks for services; 2)Health checks can be configured for various acceleration regions; 3)The detection health check mechanism works properly. 4 O&M management features 4.1Overview This indicator represents O&M management for acceleration. It is important when providers offer solutions to customers. 4.2Resource monitoring Resource monitoring Verify that the O&M system has the function: 1)You can view the running status of the origin server and link; 2) You can view the network resource usage of GA. 4.3Alarm management 1)Alarm threshold configuration is supported; 2)Alarm policy configuration is supported; 3)Support email or SMS notification and alarm function (optional). 4.3 Fault management 1) Support to quickly locate faults; 2) Automatic line fault detection is supported. 4.4Log management Support log viewing and downloading. 5 Metering and billing accuracy 5.1Overview This metric ensures accurate metering and billing for providers. 5.2 Metrological accuracy 1)Metering accuracy of network resources; 2)Metering and billing based on user-defined requirements. 6 Security Considerations 6.1Overview This indicator is defined as the provision of comprehensive security considerations. 6.2 Account Management User identity authentication is supported. 6.2Network access control 1)Support access control of security policies such as WAF; 2)Blacklist and whitelist can be configured for access control. 6.3 Attack protection It enables configuration and control of access frequency and bandwidth. It also supports DDoS attack detection and protection. 6.3Security and compliance Providers must support data encryption according to laws. This includes security assessments of transmitted data. 7 IANA Considerations This document has no IANA actions. 8.References 8.1 Normative references to the reference documents The listed documents are essential provisions of this document. Dated references apply only to the corresponding version. Undated references refer to the latest version available.
