Problems solved by technology

[0004] In the above process, each user device individually requests the IP address of the business server from the DNS server, which requires the administrator to configure the address information of the DNS server on each user device in advance, resulting in a large workload
Moreover, when multiple user devices request the IP address of the same business server, they apply to the DNS server once each time, resulting in a large load on the DNS server and affecting the processing performance of the DNS server.

Abstract

The invention provides a domain name resolution method and apparatus. The method comprises the steps of receiving a domain name resolution message from a domain name request device, and querying a domain name list through domain name information carried in the domain name resolution message; if the domain name information is in the domain name list, transmitting to the domain name request device a domain name response message carrying an IP address corresponding to the domain name information; if the domain name information is not in the domain name list, acquiring the IP address corresponding to the domain name information from a DNS; and recording a corresponding relation between the domain name information and the IP address in the domain name list, and transmitting the domain name response message carrying the IP address to the domain name request device. The technical scheme of the invention can be used for saving human consumption and reducing the load on the DNS.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a domain name resolution method and device. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new type of network architecture. Its core idea is to separate the control plane and forwarding plane of network equipment, and flexibly control network traffic through the SDN controller. [0003] In SDN, when a user device (such as a virtual machine, etc.) needs to access a service server, based on the domain name information provided by the service server, the user device sends a DNS request message carrying the domain name information to a DNS (DomainNameSystem, Domain Name System) server, And receive the DNS response message carrying the IP address of the service server returned by the DNS server. Based on the IP address of the service server, the user equipment can send a service message to the service server, and the service...
