Description
Technical field
The present invention relates to CDN content distribution network field, be specifically related to a kind of CDN intelligent scheduling based on redirection mechanism
Method.
Background technology
The full name of CDN is Content Delivery Network, i.e. content distributing network its objective is by existing
Internet in increase by one layer of new network architecture, the content of website is published to the network " edge " closest to user, makes
User can obtain required content nearby, improves user and accesses the response speed of website.
The Internet, from first day be born, just lacks a special central management structure, also lacks unified product
And technical standard, this point causes numerous heterogeneous networks structure the situation deposited.Compatibility between heterogeneous networks and different net
The problems such as the transmission bottleneck between network operator/ISP make the circulation of data be restricted.In terms of network transmission, last
The transmission of kilometer greatly develops broadband access along with Ge great operator, such as FTTH, mobile 3G/4G etc., has obtained the biggest alleviation；
The transmission problem of first kilometer, the i.e. service ability of client source station self, owing to the IDC bandwidth cost etc. of great number limits, cause
Server in station disposal ability and network broadband bottleneck, still there is no good solution；Middle one kilometer, i.e. client source
The transmitting procedure of the access point of the access point stood and terminal use, due to conventional internet, each operator interconnects, and not
Exchange with the data between the backbone network of region, transmit, cause the Route Blocking in transmission way and postpone to be eased.

The Internet becomes the favorite of New Times, the most progressively substitutes the broadcast mode that traditional broadcasting and TV are representative, becomes people and obtain letter
The main path of breath.People the most solely receive information, but it is mutual to move towards information, comes into network from the edge of network, become
For a part for network, live heat wave of today, let us recognizes that everyone can become a network center especially.
The development of Internet technology, creates diversified network application, data content and interactive mode.People more come
The most uses the social activities of media mode such as video, audio frequency, picture, word, amusement, information transmission, and this is necessarily to network
Response speed have higher requirement, the development need CDN power-assisted of Internet enterprises.
Developing rapidly of the Internet, brings great convenience for people, has also caused a lot of lawless person and has carried out madness
Network attack.Such as, ddos attack has become the chief threat that the Internet faces, DDoS as one the most simply but the most effective
Offensive pattern, it can make server or network be full of bulk information, consumption network bandwidth or system resource, cause network
Or system tends to paralysis and cannot provide normal network service.The website that general aiming is bigger, such as commercial company, search
Engine and the website of government department, distributed denial of service attack is that harm is maximum, be easiest to reach attack effect, be difficult to most to
One that is imperial and that follow the trail of.
But in the prior art, CDN manufacturer is local domain name server (Local DNS, the Local according to user
Domain Name Server) judge what user sources was scheduling, when the LocalDNS of user exists and arranges mistake,
CDN manufacturer will be unable to the intended node nearest with user is responded to user, easily causes user and builds even time length, speed of download
Slowly, problems such as experiencing difference is accessed.
Existing CDN arranges mistake due to LocalDNS, causes service node to choose exception, has a following two kinds situation: user
Mobile IP-> LDNS is set to the Cache node of UNICOM-> GSLB parsing distribution to UNICOM；Domestic netizen-> LDNS is set to
8.8.8.8, directly resolve to abroad, cause loading slow.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of reasonable in design based on redirection
The CDN intelligent dispatching method of mechanism, after it is opened, LocalDNS scheduling the expection CDN node obtained is accepting user's request
After, will be analyzed according to User IP, again judge that whether present node is the optimal service node of this user, the most straight
Offer service is provided；Otherwise, user's request is redirected to optimum node and services, existing CDN overall scheduling can be effectively improved
Accuracy rate, promote QoS of customer.
In order to solve the problem existing for background technology, the technical solution used in the present invention is: it is based on redirection mechanism,
Choosing of CDN service node nearby is divided into two steps: one, when user initiate user ask time, the overall situation intelligent scheduling by root
It is service node nearby expected from its distribution according to the LocalDNS of user；Two, user sends out to intended service node nearby
Playing user's request, again according to User IP, this node judges whether self is optimal service node nearby, the most directly provide
Service, otherwise, will be redirected to optimal service node nearby based on redirection mechanism by user's request.Wherein, step one is
The mode of choosing of conventional CDN service node nearby, step 2 is CDN based on redirection mechanism intelligence proposed by the invention
Dispatching method.
The method of the invention is redirected three functional modules formed by intelligent scheduling central authorities, node intelligent analysis, node；
Described intelligent scheduling central authorities are the scheduling central authorities of each service node of the whole network, different from the intelligent dispatching system GLSB of tradition CDN
It is that the intelligent scheduling central authorities in the present invention are optimal service node expected from user scheduling not only according to the LocalDNS of user,
Also need global address storehouse, intelligent scheduling strategy and correction address base are synchronized to all service nodes of the whole network, in order to each node
Again judge according to User IP and choose optimal service node；Described node intelligent analytic function module will be deployed in the whole network to be owned
In service node, its effect is to receive the global address storehouse of intelligent scheduling central synchronization, intelligent scheduling strategy and correction address
Storehouse information, and after self is chosen for intended optimal service node by GSLB, according to User IP comparison global address storehouse, intelligence
Scheduling strategy and correction address base, it is judged that whether self is real optimal service node, and if so, this GSLB foundation is described
User LocalDNS scheduling is correct, the most directly provides the user response, otherwise, illustrates that scheduling is wrong, will call node and redirect
User's request is redirected to optimal service node serve by functional module；Described redirection function is deployed in the whole network institute equally
Have in service node, its role is to the analysis result according to node intelligent analytic function module, http protocol in calling system
302 redirect, user's request is redirected to optimal service node.
After present invention have the beneficial effect that it opens, by the LocalDNS expection CDN node that obtains of scheduling accept user please
After asking, will be analyzed according to User IP, again judge that whether present node is the optimal service node of this user, the most then
Service is directly provided；Otherwise, user's request is redirected to optimum node and services, the existing CDN overall situation can be effectively improved and adjust
The accuracy rate of degree, promotes QoS of customer.

Invention, is not intended to limit the present invention.
This detailed description of the invention adopt the following technical scheme that it based on redirection mechanism, by the choosing of CDN service node nearby
Take and be divided into two steps: one, when user initiate user ask time, the overall situation intelligent scheduling be its point by the LocalDNS according to user
Join expected from one service node nearby；Two, user initiates user's request, this node root again to intended service node nearby
Judge self to be whether optimal service node the most nearby according to User IP, service is the most directly provided, otherwise, will be based on redirection
Mechanism, is redirected to optimal service node nearby by user's request.Wherein, step one is conventional CDN service node nearby
Mode of choosing, step 2 is CDN intelligent dispatching method based on redirection mechanism proposed by the invention.
The method of the invention is redirected three functional modules formed by intelligent scheduling central authorities, node intelligent analysis, node；
Described intelligent scheduling central authorities are the scheduling central authorities of each service node of the whole network, different from the intelligent dispatching system GLSB of tradition CDN
It is that the intelligent scheduling central authorities in the present invention are optimal service node expected from user scheduling not only according to the LocalDNS of user,
Also need global address storehouse, intelligent scheduling strategy and correction address base are synchronized to all service nodes of the whole network, in order to each node
Again judge according to User IP and choose optimal service node；Described node intelligent analytic function module will be deployed in the whole network to be owned
In service node, its effect is to receive the global address storehouse of intelligent scheduling central synchronization, intelligent scheduling strategy and correction address
Storehouse information, and after self is chosen for intended optimal service node by GSLB, according to User IP comparison global address storehouse, intelligence
Scheduling strategy and correction address base, it is judged that whether self is real optimal service node, and if so, this GSLB foundation is described
User LocalDNS scheduling is correct, the most directly provides the user response, otherwise, illustrates that scheduling is wrong, will call node and redirect
User's request is redirected to optimal service node serve by functional module；Described redirection function is deployed in the whole network institute equally
Have in service node, its role is to the analysis result according to node intelligent analytic function module, http protocol in calling system
302 redirect, user's request is redirected to optimal service node.
As it is shown in figure 1, browsing process is as follows:
1, user's (Shanghai Telecom) inputs resource (such as the domain name etc. of website) to be accessed at browser, and browser is to LocalDNS
(Beijing Telecom) request parsing to this domain name；
2, Local DNS(Beijing Telecom) check the local analysis result the most having saved this domain name: if a) preserving (as above
Secondary just accessing, related resolution data are retained in Local DNS), directly return to CDN global resource IP address；B) if it did not,
Then to authority's DNS sending domain name analysis request；
3, authority DNS is to the CNAME record of Local DNS response domain name；
4, Local DNS initiates user's request according to CNAME record to the GSLB of CDN；
5, GSLB is analyzed according to the Local DNS of user, sends anticipated optimal set service node IP to Local
DNS；
6, anticipated optimal set service node (Beijing Telecom) IP is responded to user by Local DNS；
7, user initiates user's request to this service node (Beijing Telecom) IP；
8, anticipated optimal set service node (Beijing Telecom) IP judges self based on node intelligent analytic function module according to User IP
Be whether the optimal service node of this user, from the graph in it can be seen that User IP is Shanghai Telecom, its Local DNS is arranged
For Beijing Telecom, hence it is evident that be not optimal service IP, therefore analyze and draw optimal service node IP (Shanghai Telecom), it is contemplated that optimal service
Node (Beijing Telecom) is again based on redirection function and this user request is redirected to optimal service node (Shanghai electricity
Letter)；
9, optimal service node (Shanghai Telecom) responds according to user's request.
As in figure 2 it is shown, principle is described as follows:
Step 1: intelligent scheduling central authorities are by information such as global address storehouse, parsing strategy, correction address bases；
Step 2: the anticipated optimal set service node drawn according to Local DNS, judges certainly based on node intelligent analytic function module
Whether body is the optimal service node servicing active user's request, the most then provide service；Otherwise, analysis draws optimal node；
Step 3: optimal node IP is synchronized to redirection function by node intelligent analytic function module；
Step 4: redirection function is initiated to redirect request to target optimal node；
Step 5: optimal service node receives the user's request that redirects, and responds user's request.
After this detailed description of the invention chooses anticipated optimal set service node via GSLB according to user LocalDNS scheduling, service
Again according to User IP, node can judge whether it is optimal node, and be redirected to optimal according to judged result by user's request
Service node, provides the user service, according to the optimal service node selection of User IP, chooses result phase with according to LocalDNS
Than more accurate, effectively the accuracy rate of optimal service node selection can be promoted to more than 99.9%, meanwhile, optimal service node
The height choosing accuracy rate directly affects the service quality quality that CDN provides the user, for big file download and Streaming Media
Business, although according to LocalDNS choose node wrong time, need to increase once redirect have a small amount of time loss, but
Owing to final optional optimal node is that user services, therefore can be greatly enhanced user's speed of download, promote user
Access and experience, and redirection mechanism supports multiple redirection strategy, such as preferential operator, operator+city, operator+save, transports
Battalion business+ great Qu, operator+country, operator+continent etc., client can be configured according to self-demand, facilitates flexibly.
The above, only in order to technical scheme to be described and unrestricted, those of ordinary skill in the art are to this
Other amendment or equivalent that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
All should contain in the middle of scope of the presently claimed invention.
