Global coverage

The acceleration of the overseas CDN of Baidu AI Cloud, relying on 200+ CDN overseas nodes distributed in 50+ countries and regions all over the world, with more than 100 T bandwidth resource reserves, effectively solves cross-border access problems, reduces access delays of overseas end users and improves service availability.

Accurate schedule

Compute the edge node address with the best quality in real time according to the user's access to network (region, operator) and the access resource address of the user to ensure that the user's request can reach Baidu CDN network at the fastest speed and obtain the website contents required.

High-performance cache

• Baidu CDN adopts self-developed high-performance cache system.
• The single device is equipped with the high-performance hardware equipment as 10-gigabit network card and SSD and the HTTPS customized acceleration device.
• Multi-level multipart cache and intelligent hierarchical storage of hot resources to maximize the hit ratio of a single machine.
• Low delay, high throughput.

Self-service development

Platform-based access, self-service configuration of acceleration; rich configuration items, supporting cache policies, cache key calculation, forward to origin, video, hotlink protection, HTTPS and other relevant configurations; refresh the cache with one button.

Security

• Baidu innovates the high-performance BLB device (Baidu Load Balance) on its own.
• Effectively defense DDOS and CC attacks.
• Access to WAF product seamlessly and effectively filter malicious requests.

Real-time monitoring

Automatically analyze the business data, and the business status can be clear; monitoring data delay is within 5 minutes, and minute- granularity real-time monitoring data report is provided.

Highly efficient forward-to-origin

• Video false traffic processing technology ensures that the video dragging is no need to request for all the data.
• Merge to process concurrent forwarded requests to origin, effectively converging origin traffic and reducing the access pressure of the origin server.
• -Determine the behaviors of forwarding to origin according to the user's behavior of reading data, that is, how much the user reads will be the amount forwarding to origin, and if the user stops, the forward to origin will stop as well. Effectively reduce the forward-to-origin rate.

Link optimization

• Multi-tunnel access to the central node, intelligent selection of the origin link.
• Backbone network access, with abundant dedicated circuit resources.
• Deeply optimized TCP/IP protocol, which can effectively ensure the user access quality.
