Embodiment 1

[0025] see figure 2 , figure 2 It is a flow chart of an embodiment of a DNS resolution method of the present invention, the embodiment is applied to a DNS server, and the flow chart may include the following steps:

[0026] Step 201: Receive a DNS request packet sent by a user equipment.

[0027] Step 202: Determine an IP address set that matches the domain name in the DNS request message and the operator to which the user equipment belongs, the IP address set includes at least two IP addresses, and the at least two IP addresses belong to the server corresponding to the above domain name IP address;

[0028] In this embodiment, the operator to which the user equipment belongs can be determined according to the source IP address in the DNS request message, wherein the operator can be China Mobile and China Unicom, etc. When the user equipment registers as a user of a certain operator, the user The device will be assigned an IP address in the network segment of the operator...

Embodiment 2

[0080] Another embodiment of a DNS resolution method of the present invention will be introduced below. This embodiment is applied to a DNS server and may include the following steps:

[0081] Step 1: receiving the DNS request message sent by the user equipment;

[0082] Step 2: Obtain the source IP address in the DNS request message, and determine the operator to which the user equipment belongs according to the source IP address;

[0083] Step 3: Query the first DNS table to determine the IP address set matching the domain name in the DNS request message and the operator to which the user equipment belongs, wherein the first DNS table records the correspondence between the domain name, operator and IP address, The determined IP address set includes at least two IP addresses, and the at least two IP addresses are the IP addresses of the server corresponding to the above domain name;

[0084] Step 4: Determine the link set corresponding to the above IP address set, wherein th...

Abstract

The invention provides a DNS resolution method and device. In the embodiment of the present invention, the DNS server determines the IP address set that matches the domain name in the DNS request message and the operator to which the user equipment belongs, and determines the link set corresponding to the IP address set, and will use the link bandwidth parameters in the The IP address of a link with the largest available bandwidth determined in the link set is returned to the user equipment, so that the subsequent data packets of the user equipment can be transmitted through the link corresponding to the IP address, thereby realizing the user equipment provided by the operator to which the user equipment belongs. Bandwidth equalization between links.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a DNS resolution method and device. Background technique [0002] At present, many DNSs (Domain Name System, Domain Name System,) are jointly built by multiple operators. The application server corresponding to the same domain name no longer has one IP address, but multiple IP addresses, and different IP addresses are associated with different operators. For example, the IP addresses IP1 and IP2 of the application server corresponding to the domain name www.c.com can be associated with China Mobile and China Unicom respectively. When receiving a DNS resolution request from a mobile user device for www.c.com, the DNS server can move to The user equipment returns IP1, so that the subsequent transmission of the message between the mobile user equipment and the application server can be transmitted through the link provided by the mobile, thereby avoiding network delay...
