Compared with other CDN service providers, Baidu AI Cloud product - CDN has advantages including precise scheduling, high-performance cache, self-service management, security protection, real-time monitoring, efficient forward-to-origin, link optimization and programmable.

• 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

  Analyze business data automatically, with clear business status; provide real-time monitoring data reports in minute granularity if the monitoring data delay is within 5 minutes; support users to download and dump logs and analyze the business data.

• 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.

• Programmable configuration

  • Baidu is the first to support nginx to extend js object.
  • The edge node executes personalized JavaScript code, which takes effect within a second in the whole network.
  • The deployment configuration is simple, which supports the customized configuration of more than ten scenarios such as access control, re-direction and speed limitation.
