Description
Technical field
The present invention relates to dns resolution technical field, in particular to a kind of DNS intelligent dispatching method based on subscriber policy.
Background technique
DNS (Domain Name System) i.e. domain name system is mutually mapped as domain name and IP address on WWW
One distributed data base, is able to use family and more easily accesses internet, remembers to be directly read by machine without spending
IP number string.By domain name, the process for finally obtaining the corresponding IP address of the domain name is called domain name mapping (or hostname resolution).
DNS Protocol operates on UDP (User Datagram Protocol, User Datagram Protocol) agreement, uses port numbers 53.
It is made of resolver and name server, domain name refer to preserve in the network domain name of All hosts and with corresponding IP
Address, and have the function of the server for translating domain names into IP address.
Common dns server is only responsible for user and parses IP record, judges that user wherefrom comes without going, meeting in this way
Cause all users that can only all be resolved in fixed IP address.And intelligent DNS judges the incoming road of user, according to the IP of user
Source is mapped to domain name in different IP address, and the IP after intellectual determination is then returned to user, to improve user's
Access speed.If the website of an enterprise covers telecommunications, Netcom, mobile three operators, equally have from three operators
Access client accesses to the enterprise site, if access user is telecom client, intelligent DNS is made after parsing User IP
Judgement, returns to user for server telecommunication station IP, accesses the corporate telecommunications website website for access user.Can also according to
The region at family returns to the Site IP nearest away from user.
Present DNS intelligent dispatching method, if the library IP is directly divided into different regions by Bind, different zones are corresponding
Domain name mapping is also different in ZONE file.Bind is realized by the way of ACL+VIEW, first determines whether the source of client's request, so
Different IP is returned afterwards.It is exactly that the list of the national library IP is classified and arranged in ACL, obtains different network type and differently
The library IP in area, the corresponding ACL file in each library IP, such as telecommunications Beijing User IP library are uniformly stored in an ACL file.
Each ACL corresponding view VIEW, ZONE are recorded in VIEW.DNS view be exactly to the same resource record according to DNS
It requests source IP addresses different, is assigned in different VIEW, so that the parsing result returned is also different.But since the library IP can
Can be from the whole nation even whole world, the classification in region is very huge, and inquiring from each library IP can take considerable time, in addition,
The list of the national library IP often changes, this results in the library IP for relying on this mode to need frequent updating to synchronize IP address
Relevant information greatly reduces the efficiency of parsing.
Based on the above situation, the present invention devises a kind of DNS intelligent dispatching method based on subscriber policy, is not necessarily to from each
The library IP progress match query parses corresponding IP address and returns to user, to improve dns resolution efficiency.
Therefore the present invention frequently matches the invalid library IP and proposes a kind of intelligent scheduling side based on subscriber policy for solution
Method judges which library IP user may be from by inquiry subscriber policy, is classified as effective library IP, looks into pinpoint again
Effective library IP is ask to return to parsing result, the invention will greatly improve analyzing efficiency.
