Explore the core features and technology behind Xiyou Accelerator
| Feature | Details |
|---|---|
| Next-gen WireGuard Protocol | Xiyou Accelerator fully implements the WireGuard protocol, with only 4,000 lines of code compared to IPsec's 600,000 lines, achieving speeds 3-5 times faster. Its streamlined code means a smaller attack surface and enhanced security, allowing you to enjoy ultimate speed without worrying about privacy breaches. |
| Audited No-Logs Policy | Xiyou Accelerator enforces the industry's strictest no-logs policy—no recording of connection times, websites accessed, IP addresses, or any browsing data. This policy has been independently audited by the renowned security firm Cure53, with a full report available, ensuring that every promise stands up to scrutiny. |
| Milliseconds-Level Intelligent Connection | Xiyou Accelerator’s intelligent routing engine continuously monitors the latency and load of global nodes to automatically match you with the optimal connection. With a one-click connection and latency as low as 15ms, you can enjoy a seamless experience whether for video conferencing, online gaming, or 4K streaming. |
| Nodes Across 80+ Countries | Xiyou 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, thereby eliminating any possibility of data retention at the hardware level. |
| One Account, 6 Devices Online Simultaneously | With a single Xiyou Accelerator account, you can protect your smartphone, computer, tablet, smart TV, and router simultaneously—up to 6 devices at once, allowing your entire family 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 | Xiyou Accelerator features a bilingual support team fluent in Chinese and English, providing 24/7 online assistance. Whether you need help with installation, connection issues, or account management, you can get instant, professional help via online chat or email, with an average response time of under 2 minutes. |
In-Depth Protocol Technology Analysis
Discover how the cutting-edge routing protocols utilized by Xiyou Accelerator deliver exceptional speed and security.
| Feature | Details |
|---|---|
| WireGuard Core Architecture | Xiyou Accelerator has built a new connection engine based on the WireGuard protocol. WireGuard implements full accelerator functionality with only about 4,000 lines of code, whereas traditional IPsec requires over 600,000 lines. More streamlined code results in a smaller attack surface, lower latency, and higher throughput. In our internal tests, the handshake speed of the WireGuard protocol is 3 times faster than IKEv2 and 8 times faster than IPsec. |
| Noise Protocol Framework Encryption | Xiyou Accelerator's implementation of WireGuard uses 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 widely validated in both academia and industry, offering forward-looking security against quantum computing attacks. |
| Intelligent Protocol Switching | In certain network environments, UDP traffic from WireGuard may be restricted. Xiyou Accelerator has an intelligent protocol switching feature that automatically detects network conditions and seamlessly switches between WireGuard, IKEv2, and our proprietary obfuscation protocol, ensuring a stable connection in any environment. The entire switching process is completed within 500 milliseconds, virtually imperceptible to users. |
| Multi-Hop and split routing | Xiyou Accelerator supports multi-hop connections, allowing data to be relayed through two or more acceleration servers, providing an extra layer of privacy for users requiring extreme anonymity. Meanwhile, the split routing feature lets you choose which applications use 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 technologies and strict privacy policies comprehensively protect your digital life.
| Feature | Details |
|---|---|
| AES-256-GCM Encryption Standard | Xiyou Accelerator uses AES-256-GCM encryption mode for all transmitted data. AES-256 is the encryption standard approved by the NSA for protecting 'top-secret' level information. Even with the most powerful supercomputers today, it would take billions of years to break. Each connection generates a unique session key, ensuring forward secrecy. |
| DNS Leak Protection | Xiyou Accelerator operates its own private DNS server cluster, ensuring that all DNS queries are resolved through an encrypted connection, eliminating the risk of DNS leaks. We also have built-in WebRTC leak protection and IPv6 leak protection to ensure your real IP address is never exposed. You can use our built-in leak testing tool at any time to verify your protection status. |
| Kill Switch | Xiyou Accelerator's network lock feature (Kill Switch) can immediately cut off all internet traffic when the acceleration connection unexpectedly drops, preventing any data from leaking unencrypted. This feature supports both system-level and application-level modes: system-level protects all traffic, while application-level only protects specified applications, providing maximum flexibility for users. |
| RAM-only Pure Memory Servers | Xiyou Accelerator’s more than 3000 servers all operate in pure RAM mode. This means that no hard drives are present on the servers, and all data is processed in memory. Upon server reboot, all data is completely cleared. Even if the server is physically seized, no user data can be extracted. This represents the highest level of data protection in the industry. |
Streaming and Entertainment Optimization
High-speed connections optimized for streaming and online entertainment, allowing you to enjoy exciting global content.
| Feature | Details |
|---|---|
| 4K Ultra HD Streaming Support | Xiyou Accelerator's high-speed nodes are specifically optimized to support the transmission needs of 4K ultra HD (2160p) video streams. Whether watching high-definition movies, live sports events, or music videos, Xiyou Accelerator provides a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can consistently exceed 500Mbps. |
| Gaming Acceleration and Low Latency | Xiyou Accelerator is specially optimized for online gaming. Our intelligent routing engine can automatically select the route with the lowest latency to game servers. In our tests, the latency connecting to Asia-Pacific game servers is as low as 10ms, and as low as 60ms for North American servers. The DDoS protection feature prevents you from suffering malicious attacks while gaming. |
| P2P and Torrent Download Optimization | Xiyou Accelerator has enabled P2P optimization features on nodes in over 30 countries globally. We do not limit the bandwidth or speed for P2P protocols such as BitTorrent, while protecting your download activities from ISP monitoring and throttling through encrypted connections. The port forwarding feature improves seeding efficiency, enabling faster upload speeds. |
| Smart Content Acceleration Technology | Xiyou Accelerator's exclusive SmartRoute technology can intelligently recognize the type of content you are accessing and automatically select the most optimized transmission path. Automatically switching to streaming-optimized nodes when watching videos, switching to high-bandwidth nodes when downloading files, and prioritizing low-latency nodes when browsing the web. The entire process is fully automated with no manual intervention required. |
