Problems solved by technology

However, not all websites can be accessed through domain names. Some websites do not register domain names due to historical reasons or other special considerations.
Especially in the enterprise network, many business systems are accessed directly through IP addresses, so the existing CDN solutions cannot play a role for sites accessed using IP addresses

Abstract

The invention discloses a method for implementing CDN for a site accessed by an IP address, comprising: receiving a user's access request to the site at a first interface of a bidirectional NAT router; according to a first NAT policy preconfigured on the first interface, at Convert the destination IP address of the access request to the IP address of the CDN node at the first interface, and send the access request to the CDN node at the second interface of the bidirectional NAT router according to the default route of the bidirectional NAT router; respond at the CDN node An access request returns cached site resources to the user. The invention also discloses a corresponding CDN system for sites visited by IP addresses.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a system and method for realizing CDN for sites accessed by using IP addresses. Background technique [0002] CDN (Content Distribution Network) refers to a computer network system connected to each other through the Internet, using the server closest to each user to send music, pictures, videos, applications and other files to users faster and more reliably. To provide high-performance, scalable and low-cost network content delivery to users. The basic idea is to avoid bottlenecks and links on the Internet that may affect the speed and stability of data transmission as much as possible, so as to make content transmission faster and more stable. Its purpose is to enable users to obtain the required content nearby, solve the situation of network congestion, and improve the response speed of users visiting websites. [0003] The existing CDN solution is to modify the domain ...
