Problems solved by technology

However, in some cases, the IP address of LDNS and the IP address of the user terminal are not in the same network. At this time, the location obtained according to the IP address of LDNS is not the real location of the user. Furthermore, GSLB dispatches the CDN based on the wrong location of the user. The node server may be a CDN node server across several backbone networks, rather than the CDN node server closest to the user
[0004] That is to say, the existing scheduling method will cause the local CDN node server to access resources, but users need to access content across the backbone network. Therefore, not only does it fail to improve the response speed of users accessing websites, but it also increases backbone network traffic. Increase the pressure of backbone network expansion

Embodiment 1

[0033] An embodiment of the present invention provides a scheduling system 20, such as figure 2 As shown, it includes: LDNS 201 , a first interactive server 202 , a second interactive server 203 , a GSLB device 204 and at least one CDN node server 205 , and the IP address of the GSLB device 204 is only visible to the second interactive server 203 .

[0034] Among them, LDNS201 is used for receiving the domain name query request message sent by the user through the user terminal 30, the domain name query request message includes the domain name of the target website of the service content requested by the user, and determines the domain name of the target website in the pre-configured list After entering the list, the domain name query request message is forwarded to the first interactive server 202 in a jump mode.

[0035] The first interactive server 202 is configured to receive the domain name query request message, obtain the domain name of the target website and the IP ad...

Embodiment 2

[0068] An embodiment of the present invention provides a scheduling method, which is applied to the scheduling system 20 provided in Embodiment 1 of the present invention, such as Figure 5 shown, including:

[0069] S501. The LDNS receives a domain name query request message sent by a user through a user terminal.

[0070] Wherein, the domain name query request message includes the domain name of the target website of the service content requested by the user.

[0071] S502. After determining that the domain name of the target website is in the pre-configured list, the LDNS forwards the domain name query request message to the first interaction server in a jump mode.

[0072] S503. The first interactive server receives the domain name query request message, obtains the domain name of the target website and the Internet Protocol IP address of the user terminal according to the domain name query request message, and adds the user terminal IP address to the domain name query re...

Abstract

The embodiment of the invention provides a scheduling system and method, and the system and method can achieve more precise scheduling, improves the access speed, and improves the user experience. The system comprises an LDNS, a first interaction server, a second interaction server, GSLB equipment, and at least one CDN node server. The LDNS is used for transmitting a domain name querying request message to the first interaction server in a mode of skip after the domain name of a target website is determined to be in a pre-configuration list. The first interaction server is used for obtaining the domain name of the target website and the IP address of a user terminal, and adding the IP address of the user terminal to the domain name querying request message. The second interaction server is used for obtaining the IP address of the user terminal, and deleting the PI address of the user terminal, obtaining a second message, taking the IP address of the user terminal as the source address and transmitting the second message to the GSLB equipment. The GSLB equipment is used for obtaining the IP address of the user terminal, and carrying out the scheduling of at least one CDN node server for serving for a user. The system is suitable for the technical field of communication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a scheduling system and method. Background technique [0002] Content Delivery Network (English: Content Delivery Network, referred to as: CDN) is an intelligent virtual network built on the existing Internet, such as figure 1 As shown, the basic principle is to widely distribute CDN node servers in areas where user visits are relatively concentrated. When users visit a website, the global load technology is used to dispatch the user's access request to the nearest CDN node server that can provide services for users. In order to improve the response speed and experience effect of users visiting the website. [0003] At present, the existing CDN adopts the global DNS scheduling method, that is, the user terminal initiates a domain name resolution request for the target website to the local domain name system (English: Local Domain System, LDNS for short), and then ...
