Explore the core features and technology behind Diandian Accelerator
Next-Generation WireGuard Protocol
Diandian Accelerator fully implements the WireGuard protocol, with a codebase only 1/100th that of IPsec, yet it delivers 3-5 times the transmission speed. A leaner codebase means a smaller attack surface and higher security, allowing you to enjoy top-notch speed without worrying about privacy breaches.
Audited No-Logs Policy
Diandian Accelerator adheres to the strictest no-logs policy in the industry—we do not log your connection times, accessed websites, IP addresses, or any browsing data. This policy has been independently audited by the internationally recognized security agency Cure53, with a comprehensive report publicly released to ensure every claim can withstand scrutiny.
Millisecond-Level Smart Connections
Diandian Accelerator boasts a smart routing engine that monitors latency and load conditions of global nodes in real-time, automatically matching you to the optimal route. One-click connection brings latency down to as low as 15ms, ensuring a seamless experience whether you're in video conferences, online gaming, or streaming 4K content.
Coverage in Over 80 Countries
Diandian Accelerator has deployed over 3000 high-speed servers across more than 80 countries and regions, including North America, Europe, Asia Pacific, South America, and the Middle East. Each server operates in pure RAM mode, erasing all data upon reboot, effectively eliminating the risk of data retention at the hardware level.
One Account, 6 Devices Online Simultaneously
With a single Diandian Accelerator account, you can concurrently protect your phone, computer, tablet, smart TV, and router—up to 6 devices online at once, allowing family members to share a secure network without extra costs. After configuring your router, you can even protect IoT devices that do not support accelerator.
24/7 Professional Customer Support
Diandian Accelerator has a bilingual customer support team available around the clock, offering assistance in Chinese and English. Whether you face issues with installation, connectivity, or account management, you can receive immediate, professional help through online chat or email, with an average response time of under 2 minutes.
In-Depth Analysis of Protocol Technology
Understand how the cutting-edge routing protocols used by Diandian Accelerator provide extreme speed and security.
WireGuard Core Architecture
Diandian Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard achieves full accelerator functionality with only about 4000 lines of code, whereas traditional IPsec requires over 600,000 lines. A simplified codebase results in a smaller attack surface, lower latency, and higher throughput. In our internal testing, the handshake speed of the WireGuard protocol is 3 times faster than IKEv2 and 8 times faster than IPsec.
Noise Protocol Framework Encryption
Diandian Accelerator's WireGuard implementation utilizes the Noise Protocol Framework for key exchange, employing Curve25519 for ECDH key agreement, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been extensively validated in academia and industry, providing proactive security against quantum computing attacks.
Smart Protocol Switching
In certain network environments, the UDP traffic of WireGuard may be restricted. Diandian Accelerator features built-in smart protocol switching, automatically detecting network conditions and seamlessly switching between WireGuard, IKEv2, and our proprietary obfuscation protocol to ensure stable connections in any environment. The entire switching process occurs within 500 milliseconds, making it nearly imperceptible to users.
Multi-Hop and split routing
Diandian Accelerator supports multi-hop connections, allowing data to relay through two or more acceleration servers for an extra layer of privacy for users in need of maximum anonymity. Additionally, the split routing feature lets you choose which applications go through the accelerator and which connect directly to the local network, achieving the best balance between performance and security.
Encryption and Privacy Protection
Multi-layer encryption technology and stringent privacy policies comprehensively protect your digital life.
AES-256-GCM Encryption Standard
Diandian Accelerator utilizes AES-256-GCM encryption mode to secure all transmitted data. AES-256 is currently the encryption standard approved by the US National Security Agency (NSA) for protecting 'top secret' information. Even with the most powerful supercomputers, it would take billions of years to crack. Each connection generates a unique session key, ensuring forward secrecy.
DNS Leak Protection
Diandian Accelerator runs its own private DNS server cluster, with all DNS queries processed through an encrypted connection, eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection, ensuring your real IP address is never exposed under any circumstances. You can verify your protection status at any time using the built-in leak testing tool.
Kill Switch
Diandian Accelerator's network lock feature (Kill Switch) immediately disconnects all internet traffic in the event of an unexpected acceleration connection drop, preventing any data from leaking in an unencrypted state. This feature supports both system-level and application-level modes: system-level protects all traffic, while application-level only protects specified applications, offering maximum flexibility to users.
RAM-Only Pure Memory Servers
Diandian Accelerator's 3000+ servers operate in pure RAM mode. This means there are no hard drives on the servers, with all data processed solely in memory. Upon each server reboot, all data is completely cleared. Even if a server is physically seized, no user data can be extracted. This represents the highest level of data protection standard in the industry.
Streaming and Entertainment Optimization
High-speed connections specially optimized for streaming and online entertainment, allowing you to enjoy exciting global content.
4K Ultra HD Streaming Support
Diandian Accelerator's high-speed nodes are specially optimized to consistently handle the demands of 4K ultra HD (2160p) video streaming. Whether for high-definition movies, live sports events, or music videos, Diandian Accelerator provides a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can reliably exceed 500Mbps.
Gaming Acceleration and Low Latency
Diandian Accelerator is optimized for online gaming. Our intelligent routing engine automatically selects the route with the lowest latency to game servers. In our tests, latency to Asia-Pacific game servers is as low as 10ms, and as low as 60ms to North America servers. DDoS protection features prevent you from being targeted by malicious attacks during gameplay.
P2P and Torrent Download Optimization
Diandian Accelerator enables P2P optimization across nodes in over 30 countries. We do not restrict the bandwidth or speed of P2P protocols like BitTorrent, while ensuring your download activities remain shielded from ISP monitoring and throttling through encrypted connections. Port forwarding can boost seeding efficiency and support faster upload speeds.
Smart Content Acceleration Technology
Diandian Accelerator's proprietary SmartRoute technology intelligently identifies the type of content you are accessing and automatically selects the most optimized transmission path. During video watching, it switches to a streaming-optimized node; during file downloads, it connects to high-bandwidth nodes; and for web browsing, it prioritizes low-latency nodes. The entire process is fully automated with no manual intervention required.
