Content Delivery Network

Content delivery network (CDN) is a content delivery acceleration service provided based on the wide range of network nodes of eSurfing Cloud distributed all over the world. It distributes content from origins to edge nodes closest to the user so that the user can obtain the required content nearby. This resolves the issue of access delay caused by cross-carriers access, cross-region access, server performance and increases the response speed and success rate of user access.

Product Advantages

Easy to deploy and maintain

Only need once CNAME to achieve website acceleration without changing the website topology. The product takes the cloud native technology as the "core", inherits the philosophy of DevOps and realizes automation of development, testing, operation and maintenance.

Efficient and ultimate acceleration experience

High-quality network nodes are selected to fully guarantee the stability of network. Protocols of all layers and kernel parameters are optimized in an in-depth manner so that ultra-high definition content can be quickly transmitted.

Secure and reliable transmission

The product supports IP blacklist and whitelist, referer based hotlink protection, timestamp hotlink protection, remote authentication hotlink protection and access frequency control and rejects illegal requests and malicious attacks. The product supports the full-link HTTPS secure transmission solution to prevent hijacking and tampering and protect data security.

All-round after-sales services

We provide 7x24-hour technical support and one-to-one exclusive project managers for VIP customers. Nodes on the entire network perform monitoring in real time to guarantee high availability of services.

Features
Cache control With the development of business derived from the new cache configuration needs, we can provide customers with flexible cache control policies, adapt to a variety of application scenarios, to achieve better acceleration experience.
Origin control By supporting flexible back-to-origin methods and back-to-origin bandwidth control policies, it can adapt to different customers' origin configuration requirements while achieving back-to-origin cost control and improving service availability.
Access control In order to cope with the high cost of hotlink theft to customers, we support different levels of hotlink protection solutions and access control policies to help customers effectively resolve the problem of hotlink theft.
Supported protocols In order to meet the relevant regulatory requirements, we can provide customers with IPv4/IPv6 dual-stack nodes to meet their IPv6 usage needs, and support http3.0 to provide faster and more stable access experience for customers in weak network environments.
Transmission Optimization In order to improve the transmission efficiency between CDN nodes, we have reduced the transmission latency and greatly improved the CDN acceleration experience through our self-developed private transmission protocol and link optimization.
Self-service The CDN console supports rich customer self-service features, including statistical analysis, content management, log download, etc., which greatly facilitates customers to do business-level analysis and management, as an important basis for business decisions.
Value-Added Service Support the identification of image content compliance in CDN distribution, such as the identification of pornographic images, and once the problematic images are found, a network-wide ban will be issued in a timely manner, thus effectively helping customers to avoid policy or legal risks.

Scenarios

< >
  • Static acceleration
  • Download acceleration
  • Video-on-demand acceleration
Applicable scenarios
  • Various websites such as portals, news media websites, e-commerce platform websites and entertainment information websites require high loading speed and accuracy of static content such as images, html, css and js. eSurfing Cloud CDN caches static content in edge nodes close to users, and distributes static content to users quickly when they visit the website, significantly improving the loading speed of the website.
Recommended solution
  • Content audit solution and object-oriented storage.
Solution Advantages
  • Based on EDNS accurate dispatching system, the carrier-grade accurate IP address library refined to the region or city granularity accurately allocates the best nodes with excellent performance to customers.
  • Through policies such as file prefetch, compressed response and HTTP2.0, the product increases the access hit rate, reduces unnecessary data transmission, shortens the connection time and effectively increases the content response speed.
  • With the help of the AI image recognition technology, the product reviews images accelerated by CDN, identifies pornographic, violent and terrorist content, supports exporting illegal image URLs and bans illegal content.
