Description
Technical field
The present invention relates to Internet technical field, more particularly, to a kind of intelligent scheduling skill based on dynamic IP resource pool
Art.
Background technology
With the development of society, Internet user's rapid growth has driven flourishing for internet economy, mobile interchange
Net, ecommerce, Internet video, branded network advertisement, online recruitment, online game etc. are rapidly developed in the extremely short time
And numerous users are have accumulated, become a part indispensable in people's life.
Allow people increasingly to pay close attention to the renewal of Internet technology, how more preferably faster and more easily to share Internet resources,
As the common focus of people.
The domain name that everybody accesses website input can be parsed into IP, the final content for accessing IP and showing website, then, domain
It is exactly to be realized by dns resolution that name, which becomes IP,.DNS be computer domain name system (Domain Name System or
Domain Name Service) abbreviation, it is made up of resolver and name server.Name server refers to preserve
There are the domain name of All hosts and corresponding IP address in the network, and with the server that domain name is converted to IP address function.It is logical
In the case of often, a domain name can parse one or more IP address, and multiple IP will form IP resources banks, and resources bank
In IP address may constantly change with the needs of business, particularly, it is necessary to be taken according to CDN node in CDN business
It is engaged in quality, translates domain names into as the optimal IP address of service quality, so need keeper constantly to be adjusted to IP resources banks
It is whole, to adapt to the change of CDN states of affairs and service quality.
CDN full name is Content Delivery Network, i.e. content distributing network.Its basic ideas is as far as possible
Avoid being possible to influenceing the bottleneck and link of data transmission bauds and stability on internet, make content transmission faster, it is more steady
It is fixed, by placing one on the existing Internet basic layer intelligent virtual net that node server formed everywhere in network
Network, CDN system can be in real time according to the connection of network traffics and each node, load state and the distance to user and responses
The integrated informations such as time re-direct the request of user on the service node nearest from user.
Prior art is according to the demand of business be adjusted IP resources banks by keeper, main side
Method is as follows：
1. being called in advance to one group of IP address of domain name static state setting for domain name mapping, a basic IP resources bank is formed；
2. pair IP address group, from the angle for preventing empty parsing, availability and quality, it is standby that this group of IP address is split into one-level
Part, two level backup and three-level backup etc., or cold standby, hot standby etc. are arranged to, form IP address back mechanism；
3. when machine situation occurs delaying in server, policy resolution can be changed according to machine-cut of delaying and go out standby IP address, just protected
Demonstrate,prove the availability of server.
Existing scheme, which can guarantee that, to be translated domain names into multiple IP address, is not in the phenomenon of empty parsing, can be inadequate
Guarantee business is normal；Due to there is provided machine backup policy of delaying, when server delays machine, can substantially realize and change plan by machine-cut of delaying
Different secondary ip address is slightly parsed, can so realize the continuity and availability of business to a certain extent.
It is main as follows but the shortcomings that currently available technology scheme is fairly obvious：
1. because existing scheme is to pre-set IP address by way of static, can only by virtue of experience with present node situation
It is default, therefore lack scientific basis.
2. the characteristics of because of CDN business itself, IP resources banks are very huge, and change is very frequent, therefore keeper passes through
The mode of static preset needs to set thousands of IP address, and needs to allocate repeatedly, has reached optimal dispatching effect, therefore
Existing technical scheme is for keeper, it is meant that workload is uprushed, and the maintenance management cost to IP address is very high and inadequate
Flexibly, the phenomenon of configuration error and easily occurs.
3. because existing scheme mainly carries out IP resource distributions according to the experience of keeper, it is impossible to loaded by weight proportion equal
Weighing apparatus parses IP address, therefore the IP address parsed can not truly reflect the load balancing state of server.
4. the IP address that existing scheme parses scientifically can not realize that optimal intelligence is adjusted according to node quality, availability
Degree, and be that corresponding IP address can be parsed according to the optimal node of service quality the characteristics of CDN business maximums, so as to carry out
Corresponding request scheduling, thus prior art exist for CDN business it is clearly disadvantageous.
The content of the invention
It is an object of the invention to provide a kind of intelligent scheduling technology based on dynamic IP resource pool, to solve above-mentioned background
The problem of being proposed in technology and defect.
To achieve the above object, the present invention provides following technical scheme：
A kind of intelligent scheduling technology based on dynamic IP resource pool, IP dynamic resources pond are transported by dynamic acquisition center, dynamic
Calculation center, three, dynamic IP pond part are formed, wherein：
Dynamic acquisition center is used for the quality of service data for gathering each CDN node, including node IP, bandwidth, domain name mistake
Rate, availability, dns resolution performance, the company's of building time, speed of download, three layers of error rate, compare at a slow speed, interim card rate；
Dynamic operation center is used for the data arrived according to dynamic acquisition central data, and various dynamics are obtained by algorithm computing
Coefficient, the content of computing include:Property coefficient computing, quality coefficient computing, bandwidth factor computing, comprehensive weight coefficient can be used to transport
Calculate；
Dynamic IP pond, according to each node IP address information of dynamic acquisition central data and the computing knot at dynamic operation center
Fruit shape into dynamic IP resource pool, for storing substantial amounts of IP address, the IP address in dynamic IP pond all saves comprising each CDN
Point IP every attribute:IP address, View, quality weight, bandwidth weighting, artificial weight, availability weight, comprehensive weight.
In the above-mentioned technical solutions, the detailed process used in IP dynamic resources pond is：
Q1：Dynamic acquisition then passes through dynamic operation CENTER ALGORITHM meter centrally through the IP address of dynamic acquisition CDN node
Calculate, draw every attribute of each IP address, while put the IP address after calculating into dynamic IP resource pool and stored；
Q2：In use, server is in domain name mapping, domain name is by binding IP dynamic resource pond, with obtaining corresponding IP
Location information.
As the preferred of above-mentioned technical proposal, when server delays machine, based on VIEW preferentially according to comprehensive weight, IP is entered
Row sequence, weighted value highest IP address come foremost, translate domain names into and be switched to weighted value highest IP address.
Advantages of the present invention：
A kind of intelligent scheduling technology based on dynamic IP resource pool provided in an embodiment of the present invention, global design, dispatch duty
Can, its advantage is as follows:
1. the technical scheme is carrying out carrying out IP address on the basis of comprehensive analysis to each node quality-of-service situation
Sequence, therefore each IP address can more embody the service quality of node, global design more science, therefore can preferably carry out intelligence
Can scheduling.
2. the technical scheme has abandoned prior art manual maintenance by measures such as dynamic acquisition, dynamic operations
Drawback, automatization level is high, significantly reduces the workload of manager.
Scheduling strategy is cut 3. devising failure and delaying：When server delays machine, translate domain names into and be switched to weighted value highest
IP addresses, the science that machine-cut of delaying is changed is ensure that on technological layer.
