Abstract
The invention provides a dynamic domain name service optimizing system, and relates to the field of network communication. A conventional DNS mainly has the problem of address resolution suboptimum; as a BGP service is forwarded through a destination address, BGP service access quality is relatively more greatly influenced by different addresses obtained for an identical domain name; and as the conventional domain names all provide a plurality of sets of addresses for the access of users, the satisfaction of the users in access experiences is greatly improved if an optimal resolved address can be obtained. The dynamic domain name service optimizing system comprises a DNS optimization controller, adopts an active working principle, queries all DNS results for www.abc.com according to a request of a client for the www.abc.com, puts the DNS results into a comparison list, performs connectivity checking on records in the list, determines a fastest IP address record through calculation and comparison and returns optimal IP address information to the client.
Description
Technical field
The present invention relates to network communication system, the invention provides a kind of processing DDNS service business optimization system.
Background technology
In telecommunications industry, there are many second-level runners at present, wherein there are some to use autonomous dns server LOCAL-DNS and the higher level's operator DNS of setting up to carry out address resolution inquiry, according to the information obtaining with upper strata operator DNS, in LOCAL-DNS server, having CACHE is that (BGP business is a kind of Internet product for the BGP business of second-level runner, the medium that it adopts the Routing Protocol of BGPVersion 4 to transmit as information, carry out interconnected with a plurality of operators, as: telecommunications, Netcoms etc., provide multiple exit the Internet access services.This product can utilize the bandwidth resources of each outlet for user provides single IP address section.) customer group provides address resolution inquiry service.Conventionally dns server is used two-node cluster hot backup pattern that protection and redundancy are provided; the address of dns server and extraneous intercommunication is the IP address field of second-level runner oneself application; in the whole world, can be routed; by BGP Routing Protocol, carry out intercommunication, this address does not belong to any operator (telecommunications, Netcom, Tie Tong, UNICOM etc.).The address of the parsing return information that discovery obtains from root server is at present not the most accurately, the suboptimum resolving information occurring relatively many, simultaneously, the dns address using due to second-level runner is to apply for by APNIC, do not belong to any Yi Jia operator, in test process, find to do inquiry service with the dns server of some one-level operators of this locality.
Mainly there is the problem of address resolution suboptimum in DNS service at present, with an example, if access www.sohu.com, the result of the dns resolution by second-level runner is completely different from the address field that the result of using the dns resolution of telecommunications is returned, because BGP business is to forward by order way address, so it is larger to the quality influence of BGP Operational Visit to obtain different addresses for same domain name, and because being all to provide many covers address, current domain name provides access for user, if can make user greatly promote the satisfaction of experiencing of access so can obtain an optimum parse addresses.
Summary of the invention
In order to solve the problem that is difficult at present obtain optimum parse addresses, for improving the quality of BGP business, the invention provides a kind of dynamic domain name service optimizing system, for the dns server system of second-level runner, be optimized adjustment.
Traditional dns server is according to the request feedback DNS result of client, but it is passive type, can only be that the information of receiving is returned to client, its result often has the existence of suboptimum situation, the BGP business of taking charge of for me especially, the Internet access architecture that cannot effectively utilize multilink, causes waste to resource.And this time the dynamic domain name service optimizing system of exploitation adopts active operation principle, according to the request www.abc.com of client, by inquiring about all DNS results for www.abc.com, they are put into comparison list, record in list is carried out to connectivity checks, by calculating and determine IP address record the most fast, optimized IP address information is returned to client, so, dynamic domain name service optimizing system can effectively utilize the Internet access architecture of multilink, farthest makes the bandwidth resources of operator be used.
By further promote user's access websites speed with dynamic domain name service optimizing system, improve link quality and user satisfaction, optimize BGP link, utilize rationally and effectively resource, neatly by link circuit resource load balancing reasonably, improve bandwidth availability ratio, after the secondary development for DNS service system, can solve following problem:
1. high-performance: adopt abundant strategy to be optimized multilink, select optimum entry, can provide good dns resolution service for the client of the BGP business of my department simultaneously.
2. high reliability: guarantee that system run all right can provide normal service under certain access pressure.
3. high scalability: good system extension ability, along with the increase of visit capacity can meet the constantly demand of expansion of system, can carry out artificial means and intervene DNS algorithm, improve the rich of dynamic strategy.
4. managerial: system has good manageability, for regular maintenance facilitates, (as: effective system monitoring means are provided and provide interface for general monitoring tools; The configuration management of system is convenient; Flow analysis report and Log Report are provided; Provide chinesization operation interface).

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Shown in Fig. 2, complete the specific implementation process of a DDNS service optimizes, can comprise the steps:
Step 1: client initiates address lookup request; (as client need to access www.abc.com);
Step 2:DNS optimal controller receives that inquiring about local information storehouse after Query Information has or not caching record, directly returns to client if any caching record, as carry out step 3 without caching record;
Step 3:DNS optimal controller is inquired about with the higher level's dns server setting, and the information that each dns server response domain name is returned leaves in computing buffer zone;
Step 4:DNS optimal controller carries out strategy relatively to the information in computing buffer area; By alternative, go out best domain-name information;
Step 5: optimum domain name mapping information is kept in optimization data storehouse, and upgrades the Cache cache information of DNS simultaneously;
Step 6: optimal information is returned to client.
Claims (1)
1. relate to a dynamic domain name service optimizing system of processing DDNS service business, it is characterized in that: adopt active operation principle, comprise a DNS optimal controller and an optimization data storehouse of communication connection, described optimization data storehouse is for preserving optimum domain name mapping information, described DNS optimal controller receives the address lookup request that client is initiated, according to the inquiry request www.abc.com of client, inquiry local information storehouse has or not caching record, if any caching record, directly return to client, as without caching record DNS optimal controller the higher level's dns server setting is inquired about, the result that each dns server response domain name is returned leaves in the comparison list in computing buffer zone, and the record in list is carried out to connectivity checks, by optimized algorithm, determine optimum domain name mapping information, the domain name mapping information of described optimum is kept in optimization data storehouse, upgrade the Cache cache information of DNS simultaneously, and optimum domain name mapping information is returned to client.
