SDK Shield Product Introduction

##1.1 Product ArchitectureThe "Golden Shield" secure access system consists of three core subsystems: "secure access client components (SDK, shell, etc.)", "secure access server room cluster", and "single instance control panel".Users can change the mode of directly connecting to backend application services through the integration of security access components from the original client program to connecting to local security access components through local IP addresses starting with 127. The security access components will dynamically select the link with the lowest latency to forward data to the security access server cluster, which will then forward the data to the user's backend application server. The entire forwarding process will encrypt and verify the authenticity of the client, and maintain the user's connection status during link switching to ensure uninterrupted TCP and UDP connections. Simultaneously solves the problems of UDP packet loss and out of order, achieving UDP without packet loss or out of order.##1.2 [Product Features]1. The "Golden Shield" secure access system is a new generation of intelligent distributed cloud access system. The access nodes adopt a multi data center cluster deployment mode. In the event of a failure or attack in one data center causing link congestion, the access channel will automatically adjust to other smooth nodes.2. The user connection status is synchronized in real-time between various data centers, and the user is unaware during the node switching process, while maintaining user awarenessTCP and UDP connections are uninterrupted.3. The Golden Shield security access system is deployed on the basis of multiple data centers, multiple lines, and high protection. The overall DDOS protection capability exceeds 2TB, which can effectively prevent high traffic DDOS attacks. All connections will be encrypted and verified to check their authenticity, filter out all untrue connections, achieve large-scale diversified CC attacks without error blocking, and effectively prevent the leakage of user server IP addresses, effectively preventing server intrusion.4. The client component simultaneously enables multi-path and selects the optimal path for data forwarding. When the selected optimal path fluctuates, it will automatically select another new optimal path. No matter where your server is, it can be accessed through the "Golden Shield" platform.5. After adopting the "Golden Shield" access system, the investment in access node services is greatly reduced, and server and operation costs are lowered.6. "Golden Shield" provides access statistics logs and analysis, such as user distribution areas, usage periods, historical online numbers, etc., effectively helping customers achieve precise operations.7. Provide various forms of client components for user integration, including packaging (shell) integration, referencing (calling) integration, SDK (development) integration, and other methods.8. Supported clients: Windows, Linux, Unix, IOS, Android;9. Supported server-side: All server-side applications based on TCP and UDP.10. A professional technical team provides real-time response 24/7, 365 days a year to help users solve all problems encountered in ordering, configuration, integration, and operation in a timely manner��
