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 achieving a content distribution network (CDN) for a site using an IP address for access. The method comprises the steps of receiving a site access request of a user at a first interface of a bidirectional NAT router; converting the target IP address of the access request into the IP address of a CDN node at the first interface according to a first preconfigured NAT strategy of the first interface, and sending the access request to the CDN node at a second interface of the bidirectional NAT router according to a default route of the bidirectional NAT router; and responding to the access request at the CDN node, and returning cached site resources to the user. The invention also discloses a system for achieving the CDN for the site using the IP address for access.

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 ...
