DNS query request may be initiated to same local dns server.
Step S104, local dns server obtain the IP address of the corresponding multiple edge caching nodes of local dns server
And service priority.
Such as shown in Fig. 2, in the prior art, when user's request accesses to domain name www.test.com, local dns clothes
Business device returns to the highest edge caching nodes IP address 218.30.108.32 of service priority to user.And in step of the present invention
In S102, local dns server returns to four edge caching nodes IP address of highest priority to user, is respectively the first side
Edge cache node IP address 218.30.108.32, second edge cache node IP address 218.30.108.32:50th, the 3rd edge
Cache node IP address 219.11.101.234:30th, the 4th edge caching nodes IP address 219.11.101.234:20.Wherein,
The service priority of four edge caching nodes can for example be followed successively by first edge cache node service priority 70, the second side
Edge cache node service priority 20, the 3rd edge caching nodes service priority 15, the 4th edge caching nodes service priority
Grade 15.
Step S106, local dns server divide according to the service priority of multiple edge caching nodes of acquisition to user
IP address with edge caching nodes.
Wherein, local dns server can first calculate the service priority of each edge caching nodes and all edges delay
Deposit the ratio of the service priority sum total of node.Then, local dns server is general using the ratio of each edge caching nodes
Rate is randomly assigned the IP address of each edge caching nodes to user.
By taking first edge cache node as an example, the service priority of first edge cache node and all edge caching nodes
Service priority ratio be 70/100=70%.Then, local dns server asks the DNS query of the user 70%
It distributes to first edge cache node.The situation of other edge caching nodes is handled with reference to similar method.
In above-described embodiment, by local dns server according to the service priorities of multiple edge caching nodes to user
The IP address of edge caching nodes is randomly assigned, a kind of more balanced domain name mapping scheme of load is provided, realizes basis
The service ability of edge caching nodes accesses user to edge caching nodes equilibrium assignment.

Priority, local dns server receive the IP address and service priority for multiple edge caching nodes that GSLB equipment is sent.
According to DNS record protocols of the prior art, GSLB equipment (referred to as A records) is recorded by host ip in a manner of to
The IP address of local dns server returned edge cache node.In order to which GSLB equipment returns to multiple edges to local dns server
The IP address and service priority of cache node can increase new DNS record protocol classes in existing DNS record protocols
Type.For example, increasing RR (Resource Record, resource record) type APRE, concrete numerical value can be by IANA (The
Internet Assigned Numbers Authority, interconnection network data distributor gear) it distributes.The correlation of APRE records
Parameter configuration can be for example shown in Fig. 4.Wherein, the main distinction of (referred to as A records) is recorded with host ip of the prior art
It is, APRE records occupy five bytes.Wherein, preceding four bytes are used to storing the IP address of edge caching nodes, the 5th
Byte is used to store the service priority of edge caching nodes.The data structure of APRE can be for example shown in Fig. 5.
It will be understood by those skilled in the art that the DNS response data packets that GSLB returns to local dns server can include two
Kind RR records.If local dns server supports APRE records, GSLB returns to A records to local dns server and APRE remembers
Record, local dns server are recorded using the APRE at message rear portion, ignore the A records of forepart.If local dns server does not prop up
APRE records are held, then after local dns server returns to A records and APRE records, local dns server Jin Shiyong is located at GSLB
The A records of message forepart ignore the APRE records at rear portion, so that distinct device can be compatible with APRE records.
It, can be according to the visit for accessing number of users and carrying out edge caching nodes of local dns real service in above-described embodiment
It asks, more accurately assigns the visit capacity of Internet user according to the processing capacity of fringe node.It will be local so as to avoid GSLB
DNS carrys out each edge caching nodes visit capacity and the inconsistent feelings of processing capacity caused by allocations of edge cache node as user
Condition.
Preferably, step S104 can also include：
Step S3048, local dns server is by the IP address and service priority of the multiple edge caching nodes received
Grade is being locally stored as the DNS resource records with priority, and local dns take when initiating to carry out DNS query again so as to the user
Business device is fed back accordingly according to DNS resource records.
Such as shown in Fig. 2, parameter 600 represented the life span of the DNS resource records with priority as 600 seconds, that is,
Say that the DNS resource records with priority are effective within 600 second time, the user initiates to carry out again local dns during DNS query
The feedback that server is responded according to DNS resource records.
Step S3041, local dns server is in DNS resource record of the local search with priority.
If the DNS resource records with priority have been locally stored in local dns server, local dns server can be straight
Obtain the corresponding multiple edge caching nodes of local dns server IP address and service priority.If local dns service
The DNS resource records of the local non-storage tape priority of device, then perform step S3042 to step S3046 to obtain local dns service
The IP address and service priority of the corresponding multiple edge caching nodes of device.
In above-described embodiment, the situation of the DNS resource records with priority can be locally stored in local dns server
