Description
Technical field:
The present invention relates to Internet communication technology field, be specifically related to a kind of multilink self adaptation dns resolution method and apparatus.
Background technology:
Along with the fast development of the Internet is with universal, the application based on the Internet is increasing, and how fast access the Internet becomes a lot of enterprise, unit issues that need special attention.Although access can be realized by an ISP accessing Internet, be difficult to ensure because the bottleneck existed between each ISP causes some Internet resources to access effect.
For addressing this problem, some enterprises and unit, by multiple ISP link accessing Internet, achieve good effect.From some Research Literatures both domestic and external, if the ISP of access more than three, then access efficiency can improve 20%-25%.But because user side can only adopt static routing mode accesses network, make the performance that really cannot play multilink access.
Summary of the invention:
The object of this invention is to provide a kind of multilink self adaptation dns resolution equipment, it can carry out domain name mapping adjustment according to link and server state self-adaption, resolve to user side most suitable server ip, not only ensure that the speed that user accesses but also optimize outbound, improve link-access performance, dns resolution and link scheduling are united two into one, not only ensure that the access to netwoks speed of client but also the optimization achieved outbound and scheduling.
In order to solve the problem existing for background technology, the present invention adopts following technical scheme: it comprises DNS request module 1, dns resolution module 2, link analysis module 3, routing scheduling module 4, DNS respond module 5, DNS request module 1 is connected with dns resolution module 2, dns resolution module 2 is connected with link analysis module 3, link analysis module 3 is connected with routing scheduling module 4, and routing scheduling module 4 is connected with DNS respond module 5, the DNS name resolution request that described DNS request module 1 sends for monitoring client, obtains domain name to be resolved, and this domain name is sent to dns resolution module, concrete operations flow process is: the domain name mapping request starting → monitor client, obtain domain name to be resolved → by domain name and send dns resolution module → return to, described dns resolution module 2 receives the domain name to be resolved that DNS request module sends over, nslookup resolution data storehouse, if existing resolving information, then direct taking-up from database resolves IP set, sends to DNS respond module, if without this domain name in domain name mapping database, then it is resolved in detail, obtain all application server IPs of this domain name in each link deploy, comprise each application server IP on same link and the application server IP on different link, form IP address set, this IP address set is sent to link analysis module, concrete operations flow process is: the domain name to be resolved that beginning → reception DNS request module sends → inquiry home domain name parsing storehouse → existence → obtain this domain name mapping IP from database, sends to DNS respond module, there is not → send from the name server of each this domain name of bar chain road direction respectively the parsing IP of this domain name of analysis request → obtain from each bar link, form IP address set, send to link analysis module, described link analysis module 3 receives the IP address set that dns resolution module sends, do time delay end to end from each chain way outlet respectively to each IP address in set to detect, the time delay of hop count detects, the detection of outlet bandwidth time delay, each IP address obtains three master datas: end-to-end delay, routing delay and outlet time delay, these data are carried out addition calculation by certain weights or ratio and obtains the final delay time, was sorted from small to large according to time of delay in each IP address, and determine that the final IP address set returning to user is stored in database according to predefined rule, link analysis module can also be carried out timing to the information in domain name mapping database and detected and upgrade, to ensure accuracy and the actual effect of data, concrete operations flow process is: start → obtain IP address set that dns resolution module sends or timing from storehouse, read the IP address set in territory to be updated → carry out information detection to each IP address, each IP address obtains three master datas: the average delay time obtaining each IP after end-to-end delay, routing delay and outlet time delay → be weighted these three data, after temporally being sorted in IP address according to setting rule stored in domain name mapping database, and send to respond module → return, IP address set in described routing scheduling module 4 pairs of domain name mapping databases carries out the judgement and the selection that export default route: if optimum IP address route is default route, does not need scheduling, if optimum IP address route is not default route, route adjustment is carried out to the IP address field at IP place and judges: if meet regulation rule, then the default route of this IP address field is dispatched in optimum link, and this IP address field flag information is reset, otherwise revise the flag information of this IP address field, but do not carry out routing scheduling, concrete operations flow process for: whether be default route export, if it is do not need to adjust if starting → obtaining to export selected by IP address set → inquiry high priority IP address that IP address set/timing that link analysis module sends reads territory to be updated from storehouse, if regulate several IP of judgement → IP address section to be the high IP of priority if not then carrying out route, and the access times of these IP and quantity reach the threshold value preset, then this IP address field is carried out route adjustment, and by counter O reset, otherwise counter is added one, but does not carry out adjusting → returning, the optimum IP address parsed is returned to client by described DNS respond module 5, concrete operations flow process is: the IP address → by this IP address starting → monitor to send over sends to client → return.
The present invention can carry out domain name mapping adjustment according to link and server state self-adaption, resolve to user side most suitable server ip, not only ensure that the speed that user accesses but also optimize outbound, improve link-access performance, dns resolution and link scheduling are united two into one, not only ensure that the access to netwoks speed of client but also the optimization achieved outbound and scheduling.
