Wherein, described GSLB module 201 is managed respectively the first load balancing module 2021 in described first content distributing network distribution node 202, the second load balancing module 2031 in described second content distributing network distribution node 203.The first load balancing module 2021 management the first distribution node server 2022, the second distribution node server 2023 and the 3rd distribution node servers 2024 of described first content distributing network distribution node 202, the second load balancing module 2031 management the 4th distribution node server 2032 and the 5th distribution node servers 2033 in described second content distributing network distribution node 203.Content distributing network logical architecture described in the embodiment of the present invention just schematically illustrates, and in practical application, according to the difference of region and tenant's rented content distributing network resource, according to actual conditions, plans, carrys out construction content distributing network.
Described content distributing network can provide content service at least one tenant, as shown in Figure 2, suppose to exist tenant A, tenant B, the tenant C resource of rented content distributing network 20 respectively, by content grouting socket D, be connected with described content distributing network 20, described content distributing network 20 can be embodied as described tenant A, tenant B by content grouting socket D, tenant C provides content distribution service, described tenant can be ICP(Internet Content Provider, content supplier), Sohu for example, Sina etc.
It should be noted that, GSLB module is for carrying out overall scheduling according to nearby principle scheduling strategy at content distributing network to the user access request of each tenant's first user, for described each tenant's first user is selected optimum content distributing network distribution node, any one user that described each tenant's first user is described each tenant; Load balancing module for dispatching the user access request of described each tenant's first user in content distributing network distribution node, for described each tenant's first user, select distribution node server, described distribution node server provides content service for the direct first user for described each tenant.
The embodiment of the present invention provides a kind of data processing method, supposes to be applied to content distributing network 20, supposes that the first tenant is for Baidu, and the first user of Baidu is user x, as shown in Figure 3, comprising:
Network management system first arranges the configuration information of Baidu's rented content distributing network resource, described configuration information comprises the Baidu's configured bandwidth on each distribution node server and Baidu scheduling thresholding on described each distribution node server in content distributing network, and the user that described scheduling thresholding is Baidu can use Baidu to rent the limiting value of the resource of described each distribution node server.It should be noted that, the configured bandwidth of Baidu on each distribution node server and scheduling thresholding can be identical, also can be different according to the configured bandwidth size on described each the distribution node server of not coexisting of Baidu's rented content distributing network resource and scheduling thresholding.Then, described network management system sends the configuration information of Baidu on each distribution node server to the load balancing module in each content distributing network distribution node.Fig. 3 be take first load balancing module of first content distributing network distribution node in as example schematically illustrates described network management system to first content distributing network distribution node and is sent Baidu's configuration information on each distribution node server in the distribution node server of described the first load balancing module management.
Load balancing module in each content distributing network distribution node receives the configuration information of the Baidu of network management system transmission, the scheduling resource table of each distribution node server at least one distribution node server of each load balancing module management described in setting up according to each load balancing module of configuration information, configured bandwidth and the scheduling thresholding of a plurality of tenants of each load balancing module management on described distribution node server described in the scheduling resource table record of distribution node server described in each, described configured bandwidth is the bandwidth that described tenant rents.
When user x accelerates the content of access www.baidu.com by content distributing network before, first SP(Service Provider, service provider) need change to authorize DNS(Domain Name System, domain name system) configuration of server, be about to need the domain name addresses of accelerating to be configured to be redirected to acceleration domain name, for example the domain name www.baidu.com of ，Jiang Baidu is configured to accelerate the domain name www.baidu.com.cdn.net of Baidu.Concrete, user x is to the browser input domain name www.baidu.com of Baidu request service, browser is to LDNS(Local Domain Name System, home domain name system) server request Baidu domain name mapping, described LDNS is the domain name system server address of user x location, LDNS receives after Baidu's domain name mapping request, to the domain name mapping of authorized DNS server request Baidu of Baidu, this Baidu's authorized DNS server receives after Baidu's domain name mapping request, to LDNS, return and accelerate the domain name www.baidu.com.cdn.net of Baidu, after the described acceleration of LDNS reception Baidu domain name, to operator, authorize DNS to send and accelerate Baidu's domain name mapping request, described operator authorizes DNS to receive and accelerates after Baidu's domain name mapping request, to LDNS, return to national GSLB module's address, LDNS receives after the GSLB module's address in the described whole nation, GSLB module to the described whole nation sends request the domain name mapping of acceleration Baidu, after the described acceleration of the GSLB module reception Baidu domain name mapping in the whole nation, according to nearby principle scheduling strategy, dispatch, to LDNS, return to the GSLB module's address in province, user x place, LDNS receives after the GSLB module's address in province, to user x, send the GSLB module's address in described province, user x receives after the GSLB module's address in described province, user x sends user access request to GSLB module.Be that user x can find GSLB module's address according to resolving and being redirected, make user can access www.baidu.com content nearby.Any one user that described user x is Baidu.
GSLB module receives the user access request of user x, according to nearby principle scheduling strategy, to user x, send the first load balancing module address, described the first load balancing module address is the load balancing module address in first content distributing network distribution node, described nearby principle scheduling strategy is is the described user assignment distribution node server nearest apart from this user according to the user's of access websites geographical position, with respect to the load balancing module of user x and GSLB module management, user x and the first load balancing module are nearest.Therefore allow user x by the first load balancing module, to carry out the access of www.baidu.com, with respect to the load balancing module in other content distributing network distribution node in described content distributing network, described the first load balancing module is the load balancing module in the described user x optimum content distributing network distribution node that need to use.In practical application, the first load balancing module in other user of this tenant or other tenants' user and first content distributing network distribution node may be far away, but nearer with the second load balancing module in second content distributing network distribution node, so may being allowed through described the second load balancing module, other user of this tenant or other tenants' user carry out the access of website.
Example, suppose to provide time source server of www.baidu.com content in Beijing, the user that the first load balancing module in first content distributing network distribution node is Shaanxi provides content distribution service, the user that the second load balancing module in second content distributing network distribution node is Nanjing provides content distribution service, when user need to access www.baidu.com content in Xi'an, this user and the first load balancing module are nearest, can by the first load balancing module, provide www.baidu.com content for the user in Xi'an according to nearby principle scheduling strategy, when user need to access www.baidu.com content in Nanjing, this user and the second load balancing module are nearest, can by the second load balancing module, provide www.baidu.com content for the user in Nanjing according to nearby principle scheduling strategy.Described in the embodiment of the present invention, nearby principle scheduling strategy is any one in scheduling strategy, just schematically illustrate, in practical application, can also there be other scheduling strategies for the load balancing module in user assignment content distributing network distribution node is for described user provides content distribution service, make this user can be by the content of the load balancing module access websites in the content distributing network distribution node distributing.
User x receives GSLB module according to the address of the first load balancing module of nearby principle scheduling strategy distribution, sends the user access request of user x by GSLB module forwards to described the first load balancing module.Described user access request comprises the title of Baidu, subsequent step is carried out so that the first load balancing module is identified the identity of Baidu in the geographical position of described user x etc.
The first load balancing module receives after the user access request of user x of GSLB module forwards, first, according to the geographical location information of the described user x carrying in the user access request of user x, nearby principle scheduling strategy, determine in the distribution node server of described the first load balancing module management and the nearest distribution node server of the described user x Optimal Distribution node server as described user x.Suppose the first distribution node server of described the first load balancing module management and the nearest distribution node server between described user x, therefore the first distribution node server of described the first load balancing module management is distributed to described user x as Optimal Distribution node server.Then, described the first load balancing module need to judge whether described the first distribution node server has and can resource can make described user x can access the content of www.baidu.com by described the first distribution node server, dispatch to obtain to make user x access the distribution node server of the content of www.baidu.com between the distribution node server of described the first load balancing module management.Concrete scheduling process following steps 2061 are to described in step 2064, as shown in Figure 4.
The first load balancing module has all been set up scheduling resource table to the distribution node server of described the first load balancing module management, first, this first load balancing module is selected the scheduling resource table of the first distribution node server of described the first load balancing module management in all scheduling resource tables, then, described the first load balancing module is obtained configured bandwidth and the Baidu scheduling thresholding on this first distribution node server of Baidu on this first distribution node server according to the user access request of described user x in the scheduling resource table of the first distribution node server of described the first load balancing module management, again, described the first load balancing module is obtained the current dedicated bandwidth of Baidu on described the first distribution node server, may exist before this other the user of Baidu by described the first distribution node server, www.baidu.com to be conducted interviews, take described the first distribution node server-assignment to a part for the resource of Baidu, finally, the difference of the configured bandwidth using Baidu on described the first distribution node server and the Baidu current dedicated bandwidth on described the first distribution node server is as the first remaining bandwidth.
Example, suppose the bandwidth resources that 10G has rented on the first distribution node server of described the first load balancing module management in Baidu, the scheduling thresholding of Baidu on this first distribution node server is 2G, if other user of Baidu is by described the first distribution node server access www.baidu.com, taken the 8G of the bandwidth resources that on this first distribution node server, Baidu rents, now, described the first remaining bandwidth is 2G, described the first remaining bandwidth equals the scheduling thresholding of Baidu on described the first distribution node server, therefore, the first load balancing module in described the first distribution node is dispatched according to nearby principle scheduling strategy in the distribution node server of described the first load balancing module management, concrete, first, the distance with user x that described the first load balancing module is obtained described the first load balancing module management is greater than all distribution node servers of described first the first distribution node server of load balancing module management and the distance of described user x, then, described the first load balancing module is selected the nearest distribution node server with described user x in described all distribution node servers, the second distribution node server of supposing described the first load balancing module management is the nearest distribution node server with described user x, using the second distribution node server of described the first load balancing module management as the distribution node server after scheduling, obtain the address of described the second distribution node server, be about to described the second distribution node server as the suboptimum distribution node server of described user x.Especially, according to the second distribution node server described in the distance between the user of other Baidu and the second distribution node server of described the first load balancing module management and nearby principle scheduling strategy, can be the user's of other Baidu Optimal Distribution node server.
It should be noted that, if exist other user of Baidu more by the number of users of described the second distribution node server access www.baidu.com, the bandwidth resources that on this second distribution node server, Baidu rents have also been taken in a large number, now, described the second remaining bandwidth is less than or equal to the scheduling thresholding of Baidu on described the second distribution node server, , described the second remaining bandwidth is the poor of the configured bandwidth of described the first tenant on the second distribution node server and the current dedicated bandwidth of described the first tenant on the second distribution node server, therefore, described the first load balancing module is dispatched according to nearby principle scheduling strategy in the distribution node server of described the first load balancing module management again, there is the 3rd distribution node server of described the first load balancing module management, and described the 3rd distribution node server and user x's is nearest except the first distribution node server and the second distribution node server, be dispatched to the 3rd distribution node server, using described the 3rd distribution node server as suboptimum distribution node server, user x can pass through the 3rd distribution node server access www.baidu.com content.Especially, in practical application, scheduling times is unsuitable more because the speed of the distribution node server access website repeatedly providing for described user after scheduling can reduce, in a word should be for need to access the user of tenant website the described website of access is provided time the higher distribution node server of speed.If be dispatched to, do not provide while not configuring more distribution node server in the distribution node server of service or content distributing network for described user x, the access request of described user x is dispatched to back to source server, described time source server is for issuing the original site of www.baidu.com content.
The first distribution node server of step 2064, the first load balancing module management continues as user x provides content service.
If other user of Baidu is by described the first distribution node server access www.baidu.com, taken the 4G of the bandwidth resources that on the first distribution node server of described the first load balancing module management, Baidu rents, now, described the first remaining bandwidth is 6G, described the first remaining bandwidth is greater than the scheduling thresholding of Baidu on described the first distribution node server, therefore, make described user x can continue can access by described the first distribution node server the distribution node server of the content of www.baidu.com.
So, when existing at least two tenants to rent the resource of distribution node server of the load balancing module management in described first content distributing network distribution node, between distribution node server by the load balancing module management in described tenant's user-selected distribution node, dispatch simultaneously, determine the user's who distributes to described tenant distribution node server, make the speed of user's access websites of tenant described in each more stable sooner, effectively ensure tenant's content distributing network resource requirement.
Described in the invention process example assumes, the first remaining bandwidth is less than or equal to the scheduling thresholding of Baidu on described the first distribution node server, accordingly, the first load balancing module is obtained the address of the second distribution node server of the first load balancing module management in described the first distribution node.When the second remaining bandwidth is greater than the scheduling thresholding of Baidu on described the second distribution node server, perform step 207.
The first load balancing module is obtained behind the address of the second distribution node server of the first load balancing module management in described the first distribution node, first, according to the user access request of user x, described the second distribution node server obtains the second remaining bandwidth and the Baidu scheduling thresholding on described the second distribution node server, described the second remaining bandwidth is the poor of configured bandwidth and the Baidu current dedicated bandwidth on second distribution node server of Baidu on the second distribution node server, then, judge whether described the second remaining bandwidth is less than or equal to the scheduling thresholding of Baidu on described the second distribution node server.The invention process example assumes the second remaining bandwidth is greater than the scheduling thresholding of Baidu on described the second distribution node server, and described the first load balancing module sends the address of described the second distribution node server to user x.It should be noted that, describedly according to the user access request of user x, described the second distribution node server, obtain the second remaining bandwidth and the Baidu scheduling thresholding on described the second distribution node server, judge whether described the second remaining bandwidth is less than or equal to the detailed process of the scheduling thresholding of Baidu on described the second distribution node server and the detailed process of user x on the first distribution node server in like manner, and the embodiment of the present invention does not repeat them here.
Described the second distribution node server is the second distribution node server of the first load balancing module management in described first content distributing network distribution node.
User x has inputted Baidu's domain name in browser before this, the domain name that described the second distribution node server provides according to browser, by the good Baidu of configured in advance, return source server IP(Internet Protocol, the IP address of Internet protocol) Address Confirmation reality, by described the second distribution node server, to described real ip address, submit access request to again, after described the second distribution node server obtains www.baidu.com content from real ip address, the data of the www.baidu.com content that this second distribution node server is obtained return to user x, simultaneously, the data file of the www.baidu.com that this can be obtained is preserved at this second distribution node server, if use when there is the web site contents that the user of Baidu need to be by this second distribution node server access Baidu later.Now, the browser that user x is used receives the data of www.baidu.com content, shows the content of user x access www.baidu.com.
The bandwidth resources information that the second distribution node server update Baidu of step 2010, described the first load balancing module management rents.
After the second distribution node server successful access www.baidu.com of user x by described the first load balancing module management, be that described user x has taken the bandwidth resources that described the second distribution node server offers Baidu, this the second distribution node server update Baidu current dedicated bandwidth on this second distribution node server, obtain updating message, so that judge whether can fast access www.baidu.com when the second distribution node server access www.baidu.com that other user of Baidu manages by described the first load balancing module again.
