Explore the core features and technology behind Songshu Accelerator
Next-Generation WireGuard Protocol
Songshu Accelerator fully employs the WireGuard protocol, utilizing only 4,000 lines of code compared to IPsec's 600,000, delivering transfer speeds 3-5 times faster. This streamlined code leads to a smaller attack surface and enhanced security, allowing you to enjoy top speed without worrying about privacy breaches.
Audited Zero-Logging Policy
Songshu Accelerator implements the industry's most stringent zero-logging policy—no records of your connection times, websites accessed, IP addresses, or browsing data are kept. This policy has been independently audited and published by the renowned security firm Cure53, confirming that every promise withstands scrutiny.
Intelligent Millisecond Connections
Songshu Accelerator's intelligent routing engine continuously monitors global node latency and load, automatically matching you with the best route. One-click connection yields latency as low as 15ms, ensuring a smooth experience for video conferencing, online gaming, or 4K streaming.
Nodes in Over 80 Countries
Songshu Accelerator has deployed over 3000 high-speed servers across North America, Europe, Asia-Pacific, South America, and the Middle East in more than 80 countries and regions. Each server operates in pure RAM mode, erasing all data upon reboot to eliminate any possibility of data retention from the hardware level.
One Account Supports 6 Devices Simultaneously
With a single Songshu Accelerator account, you can secure your phone, computer, tablet, smart TV, and router—allowing up to 6 devices to connect simultaneously, sharing a secure network for the whole family at no additional cost. By configuring your router, you can also protect IoT devices that don’t support accelerator.
24/7 Professional Customer Support
Songshu Accelerator has a bilingual professional customer support team available 24/7. Whether it’s installation, connection issues, or account management, you can reach out via online chat or email for prompt and expert assistance, with an average response time of under 2 minutes.
In-Depth Analysis of Protocol Technology
Learn how the cutting-edge routing protocol used by Songshu Accelerator delivers exceptional speed and security
WireGuard Core Architecture
Songshu Accelerator has built a new routing engine based on the WireGuard protocol. WireGuard achieves complete accelerator functionality with approximately 4,000 lines of code, while traditional IPsec requires over 600,000 lines. This leaner code leads to a smaller attack surface, lower latency, and higher throughput. In our internal tests, the handshake speed of the WireGuard protocol is three times faster than IKEv2 and eight times faster than IPsec.
Noise Protocol Framework Encryption
Songshu Accelerator’s implementation of WireGuard employs the Noise protocol framework for key exchange, utilizing Curve25519 for ECDH key agreement, ChaCha20-Poly1305 for symmetric encryption, and BLAKE2s for hashing. This combination of cryptographic primitives has been widely validated in academia and industry, providing prospective security guarantees against quantum computing attacks.
Smart Protocol Switching
In certain network environments, UDP traffic from WireGuard may be restricted. Songshu Accelerator includes a smart 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, leaving users almost unaware.
Multi-Hop and split routing
Songshu Accelerator supports multi-hop connections, allowing data to be relayed through two or more acceleration servers, providing an extra layer of anonymity for users requiring extreme privacy. Meanwhile, the split routing feature allows you to choose which applications connect through the accelerator and which connect directly to the local network, achieving the best balance of performance and security.
Encryption and Privacy Protection
Multi-layer encryption techniques and strict privacy policies to fully protect your digital life
AES-256-GCM Encryption Standard
Songshu Accelerator employs the AES-256-GCM encryption mode to secure all transmitted data. AES-256 is currently approved by the NSA for protecting 'Top Secret' information. Even with the most powerful supercomputers available today, it would take billions of years to crack. Each connection generates a unique session key, ensuring forward secrecy.
DNS Leak Protection
Songshu Accelerator operates its own private DNS server cluster, ensuring that all DNS queries are resolved through encrypted connections, completely eliminating the risk of DNS leaks. We also include WebRTC leak protection and IPv6 leak protection, ensuring your real IP address is never exposed. You can verify your protection status at any time using our built-in leak testing tools.
Kill Switch
Songshu Accelerator’s Kill Switch feature can immediately cut off all internet traffic if the acceleration connection is unexpectedly interrupted, 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 shields specified applications, providing maximum flexibility for users.
RAM-only Pure Memory Servers
Songshu Accelerator’s 3000+ servers operate in a pure RAM mode. This means that there are no hard drives on the servers, and all data is processed solely in memory. Upon each server reboot, all data is fully cleared. Even if a server is physically seized, no user data can be extracted, meeting the highest standards of data protection in the industry.
Streaming and Entertainment Optimization
High-speed connections specifically optimized for streaming and online entertainment, allowing you to enjoy global content effortlessly
4K Ultra HD Streaming Support
Songshu Accelerator's high-speed nodes are specially optimized to reliably support the streaming demands of 4K Ultra HD (2160p) videos. Whether it’s high-definition movies, live sports events, or music videos, Songshu Accelerator provides a stable, smooth, and buffer-free viewing experience. On gigabit broadband, connection speeds can consistently hold above 500Mbps.
Gaming Acceleration and Low Latency
Songshu Accelerator has been specifically optimized for online gaming. Our smart routing engine can automatically select the route with the lowest latency to game servers. In our tests, connections to Asia-Pacific game servers achieved latencies as low as 10ms, while North American servers were as low as 60ms. DDoS protection prevents malicious attacks while you play.
P2P and Torrent Download Optimization
Songshu Accelerator has enabled P2P optimization features on nodes located in over 30 countries. We do not impose bandwidth limits or speed restrictions on P2P protocols like BitTorrent while protecting your downloading activities from ISP monitoring and throttling via encrypted connections. Our port forwarding feature enhances seeding efficiency and supports faster upload speeds.
Smart Content Acceleration Technology
Songshu Accelerator’s proprietary SmartRoute technology can intelligently identify the type of content you are accessing and automatically select the most optimized transmission path. It switches to streaming-optimized nodes when watching videos, to high-bandwidth nodes when downloading files, and prioritizes low-latency nodes when browsing. The entire process is fully automated, requiring no manual intervention.
