Description

Be applied to internet access accelerated method and device in content distribution network system
Technical field
The invention belongs to computer network field, especially relate to a kind of access to netwoks accelerated method and device that is applied to content distribution network system.
Background technology
Along with 3G, WiFi, the networks such as WiMax universal, and the continuous appearance (such as mobile phone reading, mobile TV, Mobile business etc.) of dazzling intelligent terminal and abundant dynamic application, this brings huge challenge for network of operator.According to the report of International Telecommunication Association's in January, 2012 issue, during the end of the year in 2011, whole world cellphone subscriber is 5,900,000,000, and the mobile broadband user is near 1,200,000,000.Show according to the report of in January, 2012 China inter network information center issue in Beijing, by in by the end of December, 2011, Chinese netizen's quantity breaks through 500,000,000, and wherein mobile phone netizen scale reaches 3.56 hundred million, increases by 17.5% on a year-on-year basis.
As shown in Figure 1, in traditional network service mode, user and content supplier are positioned at the two ends of service, and the Internet Service Provider connects both.The user utilizes the process of traditional network schemer access websites as follows:
At first, the user provides the domain name of wanting access websites to browser.Then, browser is resolved domain name to the name server request, to obtain IP address corresponding to this domain name.Then, browser uses resulting IP address, sends data access request to Website server.At last, the content of the data display web page returned according to Website server of browser.
After the user sends service request, need to carry out obtaining after domain name mapping through dns server the real IP of institute's access websites, then utilize this IP access websites.Under this access module, Website server is in Central Position, all visitors must directly be connected the ability access relevant content with Website server, this can bring following several problem: the first, because the open ended visit capacity of Website server is limited, if the website has been issued great or during focus message, will bring pouring in of a large number of users, the flow of website can sharply rise at short notice, causes accelerating website access to descend, even paralysis.The second, if Website server hypothesis from the far position of user, user access request just must through wide area network than multiple network node, cause long time-delay.The 3rd, when two users used the service that the heterogeneous networks service provider provides, these two users may have different services to experience (or quality).
In order to address these problems, scholars have proposed many methods.At present, CDN(content distributing network) technology is the most frequently used technology, is known about CND system and concept thereof.
Figure 2 shows that the structure chart of CDN network system.As shown in Figure 2, the CDN network mainly by original server with are connected the Edge Server that is connected with original server and consist of.Original server comprises that CDN network management center and GSLB DNS are redirected resolution system, are responsible for distribution and the management of whole CDN network.Edge Server mainly refers to the strange land distribution node, is comprised of load-balancing device, cache server two parts.CDN is by being published to web site contents near on user's fringe node, and making the user of different geographical is to obtain nearby in the access same page.So not only can alleviate the burden of source server, and can reduce the situation of flow distribution inequality in whole network, and then improve the performance of whole network.
Figure 3 shows that the browsing process of the system of CDN in Fig. 2, as shown in Figure 3, step 1: the user provides the domain name of wanting access websites to browser, and the request of domain name mapping is addressed to local dns and carries out domain name mapping; Step 2:CDN has carried out adjustment to the domain name mapping process, and what parsing obtained is another name CNAME record corresponding to this domain name, and in order to obtain real ip address, browser resolves to obtain actual fringe node IP address by the CNAME domain name; In this process, the GSLB dns resolution of use can according to geographical position and the actual network traffic information of calling party, make the user obtain the rational Edge Server IP of most probable address.Browser sends access request to Edge Server after obtaining actual IP address; Edge Server judges whether directly processing response according to the access request that browser provides, or by the original server Coordination Treatment.Edge Server will ask to preserve in this locality on the one hand, in order to using later on, on the other hand the data of obtaining be returned to client, complete the data, services process; The data that user side obtains being returned by Edge Server show later on and complete the whole data request process of browsing.
Access for the first time on principle, the Edge Server of CDN system will be got back to original server and obtain the Data Concurrent of user's request to the user.When having other users again to access same content, the CDN system will directly return to data the client, complete request/service process.We can find out by above analysis, when the CDN service provides acceleration to website visiting, can realize the generic access user transparent, namely add the later subscription client of buffer memory to need not to carry out any setting, directly the original domain name in the accelerated website of input is namely addressable.
In the CDN system, data placement is a more crucial problem, its target be with data placement among suitable Edge Server, in order to make the overall delay of user access request minimum.If user's request type comprises renewal seldom, the CDN system can copy data to Edge Server so, improves better the user and asks delay problem.But when if there are a large amount of update requests and a small amount of read request in data families (data, services), the scope that increases copy data is larger, will reduce systematic function.Because more new data may not be certain the Edge Server user who is accessing, access other Edge Servers but come from other user.Therefore, according to this situation, the most often data cell need to be arranged on the Edge Server that occurs to upgrade, and the master server of this Edge Server as this type of data family.
In addition, if when system load is relatively lower, data cell can be copied to many places in order to improve user's time delay.But, if when system load is higher, settle more data will bring larger overhead.Therefore, just need to reduce unnecessary copy this moment and settle, in order to reduce server load, improve inner time delay.
Therefore, a kind of suitable data placement method of the expectation that those skilled in the art are eager, the method copy data as required in Edge Server, can either satisfy the CDN system and have less time delay, can not bring larger load to server again.
