Massive Global Resource Pool
With resources deployed across 290+ cities on six continents and over 1,500 distributed edge nodes, Baishan’s CDN intelligently routes user requests to the nearest high-quality edge node, significantly enhancing global user access experience.
Download Cost Reduction Solution
Multi-type resource portfolio operations deliver high-quality, cost-effective CDN services for customers; origin bandwidth optimization solutions help reduce origin server costs.
Product Features
Flexible Caching Strategies
Configure cache policies based on file type, access frequency, and business logic. Precisely control cache lifecycle and refresh rules to maximize cache hit rates, reduce origin pulls, and accelerate response. Supports second-level cache purging across the entire network.
Multi-Dimensional Anti-Leeching
Offers layered anti-leech protection, including URL validation, IP allow/deny lists, and User-Agent restrictions, to prevent unauthorized access and protect content and bandwidth resources.
Cache Consistency Verification
Utilizes intelligent algorithms to ensure cache consistency with origin content. Real-time validation and updates prevent expired or corrupted cache, improving accuracy and stability in content delivery.
Origin Bandwidth Optimization
Relieves pressure on the origin server through multi-origin load balancing (primary/backup, round-robin, weighted), file prefetching, traffic shaping, and offline mode. Significantly reduces origin bandwidth and enhances availability while cutting costs.
Real-Time Business Awareness
Comprehensively monitors bandwidth, status codes, and other service metrics to quickly detect business anomalies. Offers offline and real-time log analysis to locate CDN or application-level issues. Provides detailed reports on bandwidth, requests, traffic, HTTP status codes, top URLs, IPs, UAs, and referers to give full visibility into business trends.
Application Scenarios
Large File Download Acceleration
Ideal for websites or applications centered around large file downloads, such as game installers and updates, APK packages, and audio/video content. It improves download speed, reduces distribution costs, alleviates network congestion, and helps prevent file tampering.
Billing Methods
95th Percentile Bandwidth Billing (Monthly)
Bandwidth is sampled every 5 minutes each day. The top 5% of peak values are discarded, and the highest remaining value is used for billing.
Best for: Services with highly variable bandwidth usage.
Apply Now
Daily Peak Average Bandwidth
The highest bandwidth usage is recorded each day, and the average of these daily peaks is taken at the end of the month for billing.
Best for: Businesses that require more predictable cost estimation.
Apply Now
Daily 95th Percentile Average Bandwidth
A 95th percentile bandwidth value is calculated for each day, and the monthly billing is based on the average of these daily 95th percentile values.
Best for: Businesses with short daily bandwidth peaks and overall stable traffic patterns.
Apply Now
Traffic-Based Billing
Charges are based on the actual volume of downstream traffic consumed. Simple and transparent.
Best for: Businesses with steady traffic or small to medium-scale usage.
Apply Now
One-Time Prepaid Packages
Fixed resource packages (e.g., bandwidth or traffic) are purchased in advance and consumed over time.
Best for: Short-term projects or marketing campaigns with defined resource needs.
