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, Input packet count ifInErrors abandoned because making a mistake, total amount of byte ifOutOctets sent, The output grouping number ifOutErrors abandoned because making a mistake.

If it addition, continuous three times to isp server query interface statistical data failure, it is determined that this ISP Servers off-line, can be set to 0 by the value of rest network disposal ability E of this isp server.Herein, With continuous three times to isp server query interface statistical data failure as judging isp server off-line Foundation, for a kind of preferred version, the present invention is not limited thereto.

S202, according to described interface statistics data, determine the rest network disposal ability of each isp server.

Specifically, dns server uses the rest network of each isp server of suitable Algorithm Analysis to process Ability, the present embodiment following several ways of offer:

Mode one: obtain described rest network disposal ability E according to formula (1):

Mode two: obtain described rest network disposal ability E according to formula (2):

Mode two is on the basis of mode one, it is also contemplated that isp server CPU is because having little time to process The computational methods that the output grouping number that the input packet count abandoned and interface have little time to send and abandons draws. Correspondingly, in step s 201, interface statistics data may include that the maximum data packet byte that can transmit Number ifMtu, bandwidth ifSpeed (unit is that bit is per second), total amount of byte ifInOctets received, because of Input packet count ifInErrors made a mistake and abandon, total amount of byte ifOutOctets sent, because of The output grouping number ifOutErrors made a mistake and abandon, isp server CPU because have little time process and Input packet count ifInDiscards abandoned, the output grouping number that interface has little time to send and abandons ifOutDiscards。

Mode three: obtain described rest network disposal ability E according to formula (3):

Mode three is on the basis of mode two, it is also contemplated that isp server because receiving invalidation protocol and The computational methods that the input packet count abandoned draws.Correspondingly, in step s 201, interface statistics data May include that the maximum data packet byte number ifMtu that can transmit, bandwidth ifSpeed (unit is that bit is per second), Total amount of byte ifInOctets received, input packet count ifInErrors abandoned because making a mistake, Total amount of byte ifOutOctets sent, the output grouping number ifOutErrors, ISP abandoned because making a mistake Input packet count ifInDiscards that server CPU abandons because having little time to process, interface has little time to send And the output grouping number ifOutDiscards abandoned, it is defeated that isp server abandons because receiving invalidation protocol Enter packet count ifInUnknownProtos.

Mode four: obtain described rest network disposal ability E according to formula (4):

E=∑ (ifSpeed × T/8-ifInOctets-ifOutOctets) (4)

Mode four is on the basis of mode one, ignores the packet count abandoned because of any reason and connects all The byte being subject to and send is as effective byte, and the computational methods drawn.Correspondingly, in step s 201, Interface statistics data may include that the maximum data packet byte number ifMtu that can transmit, and bandwidth ifSpeed is (single Position is that bit is per second), total amount of byte ifInOctets received, total amount of byte ifOutOctets sent.

Mode five: obtain described rest network disposal ability E according to formula (5):

Mode five all differs with the algorithm idea of aforesaid way one～mode four, is to utilize to process through upper strata Packet count indirectly analyze rest network disposal ability E.Correspondingly, in step s 201, interface Statistical data may include that the maximum data packet byte number ifMtu that can transmit, bandwidth ifSpeed (unit Per second for bit), receive and be delivered to the unicast packet number ifInUcastPkts on upper strata, receive and be delivered to Multicast packet count ifInNUcastPkts on upper strata, the unicast packet number receiving from upper strata and sending IfOutUcastPkts, multicast packet count ifOutNUcastPkts receiving from upper strata and sending.

Above in each mode, owing to statistical data is that timing updates, each ISP clothes therefore obtained The numerical value of rest network disposal ability E of business device is also that timing updates, and this numerical value services along with each ISP The actual operating state of device and change, it is believed that reflect its rest network disposal ability in real time.DNS takes Rest network disposal ability E obtaining each isp server can also be associated by business device with RR, the most fixed Time refresh RR, in order to dns server can directly obtain the residue of each isp server by inquiry RR Network throughput and its IP address.

The inquiry of the domain name request that S203, reception user terminal send.

S204, determine the first isp server that in each isp server, rest network disposal ability is the strongest.

Specifically, inquire about the RR corresponding with each isp server, obtain the rest network of each isp server Disposal ability, can be using isp server maximum for the numerical value of rest network disposal ability E as residue net The first isp server that network disposal ability is the strongest, it is possible to obtain the first isp server from RR IP address.

S205, the IP address of the first isp server is fed back to described user terminal.

The present embodiment, obtains the interface statistics of each isp server by timing to the inquiry of each isp server Data, and according to described interface statistics data, the rest network analyzing each isp server in real time processes energy Power, it is achieved when receiving the inquiry of the domain name request solution that user terminal sends, it is possible to by current time net The isp server that in network, rest network disposal ability is the strongest is supplied to user terminal, thus realizes this In the network that dns server is managed, the Appropriate application of each isp server resource and network load is reasonable Distribution, and when making user access website, the success rate of connection is protected.
