Drawings
FIG. 1 is a block diagram of an Internet CDN acceleration system based on edge computing according to the present invention;
fig. 2 is a flowchart of an internet CDN acceleration method based on edge computing according to the present invention.
Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, an internet CDN acceleration system based on edge computing adds a Cache layer between a client and a CDN Cache server, and includes the following modules,
the client is used for acquiring a domain name submitted by a user and analyzing the domain name;
the CDN domain name server is used for generating a corresponding CNAME record according to a domain name analyzed by the client, and re-analyzing the CNAME record to obtain an IP address of the CDN cache server;
the client is further used for sending a request for accessing the domain name to the CDN cache server according to the IP address;
the CDN Cache server is used for obtaining an actual IP address of the domain name through DNS analysis inside a Cache according to the domain name to be accessed by the client, and submitting an access request to the actual IP address;
and the CDN cache server is also used for returning the access data obtained from the actual IP address to the client.
The Internet CDN acceleration system based on edge computing is characterized in that a Cache layer is added between a user and a server, the request of the user is guided to the closer Cache to obtain the data of a source server, the data is mainly obtained by taking over a DNS, the user access is gridded and marginalized, the pressure of a core server is greatly reduced, and the access speed can be accelerated.
In the present embodiment of the present invention,
preferably, the client is specifically configured to invoke a domain name resolution library to resolve a domain name submitted by a user by using a DNS of a browser.
Preferably, the CDN domain name server is specifically configured to re-resolve the CNAME record using a global load balancing DNS resolution method to obtain an IP address of the CDN cache server. The DNS calls a domain name resolution library to resolve the domain name, and since the CDN adjusts the domain name resolution process, the domain name resolution library generally obtains a CNAME record corresponding to the domain name, and in order to obtain an IP address of the CDN cache server, the DNS needs to resolve the obtained CNAME domain name again.
Preferably, the CDN cache server is further configured to obtain access data from the actual IP address and store the access data locally for later use.
Preferably, the client is further configured to display access data returned by the CDN cache server.
In the system of the invention, in order to realize the transparency to common users (namely, after the cache is added, the client side does not need to carry out any setting and can access by directly using the original domain name of the accelerated website), and also to reduce the influence on ICP (Internet protocol) while providing the acceleration service for the specified website, only the domain name resolution part in the whole access process needs to be modified so as to realize the transparent acceleration service.
Based on the internet CDN acceleration system based on the edge calculation, the invention also provides an internet CDN acceleration method based on the edge calculation.
As shown in fig. 2, an internet CDN acceleration method based on edge computing, which performs acceleration by using the above-mentioned internet CDN acceleration system based on edge computing, includes the following steps,
a client acquires a domain name submitted by a user and analyzes the domain name;
the CDN domain name server generates a corresponding CNAME record according to a domain name analyzed by the client, and re-analyzes the CNAME record to obtain an IP address of the CDN cache server;
the client sends a request for accessing the domain name to the CDN cache server according to the IP address;
the CDN Cache server obtains an actual IP address of the domain name through DNS analysis inside Cache according to the domain name to be accessed by the client, and submits an access request to the actual IP address;
and the CDN cache server obtains access data from the actual IP address and returns the access data to the client.
In this particular embodiment:
preferably, the client specifically uses a DNS of the browser to call a domain name resolution library to resolve the domain name submitted by the user.
Preferably, the CDN domain name server re-resolves the CNAME record using a global load balancing DNS resolution method to obtain an IP address of the CDN cache server.
Preferably, the CDN cache server obtains access data from the actual IP address and then locally stores the access data.
Preferably, the client further displays access data returned by the CDN cache server.
The internet CDN acceleration method based on edge computing is characterized in that a Cache layer is added between a user and a server, the request of the user is guided to the closer Cache to obtain the data of a source server, the method is mainly realized by taking over a DNS, the user access is gridded and marginalized, the pressure of a core server is greatly reduced, and the access speed can be accelerated.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
