Strong Technical Expertise

eSurfing Cloud continuously innovates core technologies, independently developing several key technologies based on EDNS for precise traffic scheduling, intelligent and efficient caching, and efficient private transmission protocols, ensuring customers get an optimal acceleration experience.

Precise Traffic Scheduling : Supports precise scheduling and node sinking based on EDNS, achieving user request redirection to nearby sinking nodes using 302 HTTP scheduling.
Intelligent Efficient Caching : Utilizes a three-tier architecture of memory, SSD, and mechanical disks, with a self-developed intelligent cache migration algorithm that dynamically migrates files based on user access frequency, ensuring valuable memory space is always used for "useful" content for better performance.
Deep Protocol Optimization : By adjusting congestion algorithms and packet loss detection algorithms, and deeply optimizing transmission layer protocols and kernel parameters, we can rapidly transmit website content.

Secure Transmission Guarantee

Multi-level, multi-dimension security access control effectively protects customer content copyrights.

Access Control : Supports multiple access control methods like Referer anti-leech, UA black/whitelist, IP black/whitelist, URL authentication, and remote authentication anti-leech to reject illegal requests and malicious attacks.
Full-Link HTTPS : Supports full-link HTTPS secure transmission to prevent hijacking and tampering, ensuring data security.
HTTPDNS Anti-Hijacking : Allows users to access eSurfing Cloud servers via HTTPDNS protocol, bypassing carrier LocalDNS resolution to avoid domain hijacking during the resolution phase.
