Description
Technical field
The present embodiments relate to communication technology, particularly relate to a kind of inquiry of the domain name processing method, server
And system.
Background technology
(Domain Name System, is called for short domain name system: DNS) be a kind of for Internet user
(Internet Protocol is called for short: IP) to provide domain name (Domain Name) and Internet protocol
The service system of location conversion.
Universal along with Internet technology, ISP (Internet Service Provider,
It is called for short: ISP) cannot support from the access of a large number of users, ISP on the Internet with separate unit isp server
Need to dispose multiple stage isp server to realize load sharing for the website of oneself.These isp servers
It is mapped to the domain name of this website, the most same domain name, but each isp server uses the most respectively
Same IP address.On dns server, record has between the IP address of domain name and each isp server
Mapping relations, referred to as resource record (Resource Record, be called for short: RR).User terminal leads to
When crossing domain name access website, dns server can choose a RR from data base, this RR
Corresponding IP address is supplied to user terminal, so that user terminal can be visited according to this IP address
Ask the isp server of correspondence.
The dns server of prior art uses the mode being polled RR to provide to user terminal
The IP address of isp server, when certain isp server breaks down or off-line, or certain ISP
When the load of server is the biggest, its IP address still can be supplied to user by dns server
Terminal, thus cause user terminal relatively low to access failure or the access speed of website.

Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with this
Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.
The user terminal related in the application, refers to provide a user with data communication with the Internet
Equipment, can be wireless terminal can also be catv terminal, concrete form can be desktop computer, notebook
Computer, panel computer etc..
Fig. 1 is the flow chart of inquiry of the domain name processing method one embodiment of the present invention, the execution master of this embodiment
Body is dns server, as it is shown in figure 1, the method for the present embodiment may include that
The inquiry of the domain name request that step 101, reception user terminal send.
Concrete scene can be that user passes through the concrete website of user terminal access one, then user terminal
Send the inquiry of the domain name request of this website to dns server, now, dns server receives this territory
Name inquiry request.
Step 102, determine the first isp server that in each isp server, rest network disposal ability is the strongest.
Specifically, dns server is in running, in spite of receiving disappearing of user terminal transmission
Breath, dns server can pass through Simple Network Management Protocol (Simple Network Management
Protocol, is called for short: SNMP), and timing to each isp server acquisition interface statistical data, such as, carries
The total amount of byte that total amount of byte ifInOctets that wide ifSpeed, interface have received, interface have sent
IfOutOctets etc., use specific algorithm, and the rest network that such as can set isp server processes energy
Power E is: the total amount of byte that fixed cycle inner joint can transmit deducts and receives at this fixed cycle inner joint
The total amount of byte sent, it is thus achieved that rest network disposal ability E of each isp server.A certain ISP
Rest network disposal ability E of server reflects and is able to receive that at this isp server of current time, locates
The size of the data volume of reason and transmission and the speed of response speed, if the residue net of an isp server
The numerical value of network disposal ability E is the biggest, and the data that this isp server is able to receive that, processes and sends are described
Measuring the biggest, response speed is the fastest, say, that the connected success rate of user terminal is the biggest and user
The response speed of the website that terminal is experienced is the fastest.
Therefore, when receiving the inquiry of the domain name request that user terminal sends, dns server can be by this
The isp server of the numerical value maximum of one moment rest network disposal ability E is as rest network disposal ability
The first the strongest isp server.
Step 103, the IP address of described first isp server is fed back to described user terminal.
Specifically, dns server can obtain the IP address of the first isp server by inquiry RR,
And this IP address is fed back to user terminal.
The present embodiment, after dns server is by asking in the inquiry of the domain name receiving user terminal transmission,
First determine the first isp server that rest network disposal ability is the strongest in each isp server of current time,
Again the IP address of this first isp server is fed back to user terminal, it is achieved to this dns server institute
In the network of management, the Appropriate application of each isp server resource and the reasonable distribution of network load, also make
The isp server that user terminal is connected when accessing website is always rest network in current network and processes
The isp server that ability is the strongest, thus improve success rate and the access speed of user terminal access website,
So that user obtains the Consumer's Experience of optimum, thus improve user satisfaction.
Use several specific embodiment below, the technical scheme of embodiment of the method shown in Fig. 1 is carried out in detail
Describe in detail bright.
Fig. 2 is the flow chart of inquiry of the domain name another embodiment of processing method of the present invention, the execution of this embodiment
Main body is dns server, as in figure 2 it is shown, the method for the present embodiment, may include that
S201, to each isp server inquiry obtain each isp server interface statistics data.
Specifically, dns server can be looked into the ability of each isp server transmission snmp protocol in timing
Ask request message, receive the capability query response message of the snmp protocol of each isp server feedback, respectively
Capability query response message comprises the interface statistics data of the isp server of correspondence.
Described interface statistics data can be management information bank version 2 (Management Information
Base version 2, is called for short: at least one data in network interface item ifEntry in MIB-2).
MIB-2 is in the management object database under internet device administrative standard agreement SNMP
Branch, its branch node is 1.3.6.1.2.1, (i.e. iso.org.dod.internet.mgmt.mib-2).MIB-2
Define TCP/IP (Transfer Control Protocol/Internet Protocol, letter
Claim: management information TCP/IP), wherein, including network interface item ifEntry.
In described interface statistics data for example, network interface item ifEntry: the maximum data packet that can transmit
Byte number ifMtu, bandwidth ifSpeed (unit is that bit is per second), total amount of byte ifInOctets received,
