Scheduling thresholding, described configured bandwidth is the bandwidth that described tenant rents.
Step 203, user x send user access request to GSLB module.
Before user x accelerates the content of access www.baidu.com by content distributing network, SP first（Service
Provider, service provider）Change is needed to authorize DNS（Domain Name System, domain name system）The configuration of server,
The domain name addresses accelerating will be needed to be configured to be redirected to acceleration domain name, for example, by Baidu's domain name www.baidu.com configuration
For accelerating Baidu's domain name www.baidu.com.cdn.net.Specifically, user x is to browser input Baidu domain name
Www.baidu.com request service, browser is to LDNS（Local Domain Name System, local domain name system）Service
The domain name mapping of device request Baidu, described LDNS is the domain name system server address of user x location, and LDNS receives Baidu domain
After name analysis request, to the domain name mapping of authorized DNS server request Baidu of Baidu, this Baidu's authorized DNS server receives Baidu
After domain name mapping request, return to LDNS and accelerate Baidu's domain name www.baidu.com.cdn.net, LDNS receives described acceleration hundred
After degree domain name, authorize DNS to send to operator and accelerate Baidu's domain name mapping request, described operator authorizes DNS to receive acceleration hundred
After degree domain name mapping request, return the GSLB module's address in the whole nation to LDNS, LDNS receives the overall situation in the described whole nation
Behind load balancing module address, send request to the GSLB module in the described whole nation and accelerate Baidu's domain name mapping, the whole nation
GSLB module receive described acceleration Baidu domain name mapping after, be scheduling according to nearby principle scheduling strategy, to
LDNS returns the GSLB module's address in user x place province, and LDNS receives the GSLB module ground in province
Behind location, send the GSLB module's address in described province to user x, user x receives the overall situation load in described province all
After weighing apparatus module's address, user x sends user access request to GSLB module.I.e. user x can be according to parsing and weight
Orientation finds GSLB module's address so that user can access www.baidu.com content nearby.Described user x is Baidu
Any one user.
Step 204, GSLB module send the first load balancing module address to user x.
The user access request of GSLB module receive user x, sends out to user x according to nearby principle scheduling strategy
Send the first load balancing module address, described first load balancing module address is in first content distribution network distribution node
Load balancing module address, described nearby principle scheduling strategy is the geographical position according to the user accessing website is described user
Distribution is apart from the nearest distribution node server of this user, the i.e. load with respect to user x and GSLB module management
Balance module, user x is closest with the first load balancing module.User x is therefore allowed to enter by the first load balancing module
The access of row www.baidu.com, equal with respect to the load in content distributing network distribution nodes other in described content distributing network
Weighing apparatus module, described first load balancing module is that described user x needs in the content distributing network distribution node of optimum of use
Load balancing module.In practical application, other users of this tenant or the user of other tenants distribute net with first content
The first load balancing module in network distribution node may farther out, but with the second content distributing network distribution node in second
Load balancing module is nearer, so the user of other users of this tenant or other tenants may be allowed through described second
Load balancing module carries out the access of website.
Example it is assumed that provide www.baidu.com content returns source server in Beijing, first content distribution network distribution section
The first load balancing module in point provides content distribution service for the user in Shaanxi, in the second content distributing network distribution node
The second load balancing module for Nanjing user provide content distribution service, when user Xi'an need access www.baidu.com in
Rong Shi, this user is closest with the first load balancing module, then can pass through first according to nearby principle scheduling strategy and load
Balance module is that the user in Xi'an provides www.baidu.com content, when user needs to access www.baidu.com content in Nanjing, should
User is closest with the second load balancing module, then can pass through the second load balancing module according to nearby principle scheduling strategy
It is the user's offer www.baidu.com content in Nanjing.Nearby principle scheduling strategy described in the embodiment of the present invention is in scheduling strategy
Any one, simply schematically illustrate, and other scheduling strategies can also be had in practical application to distribute content distributing network for user
Load balancing module in distribution node provides content distribution service for described user so that this user can be by distribution
Load balancing module in content distributing network distribution node accesses the content of website.
Step 205, user x send user access request to the first load balancing module.
User x receives the first load balancing module that GSLB module is distributed according to nearby principle scheduling strategy
Address, by GSLB module forwards to described first load balancing module send user x user access request.
Described user access request includes the title of Baidu, geographical position of described user x etc., comes in order to the first load balancing module
The identity of identification Baidu is executing subsequent step.
Step 206, the first load balancing module distribute the first distribution node server for user x.
After first load balancing module receives the user access request of user x of GSLB module forwards, first
Elder generation, the geographical location information of described user x carrying in the user access request according to user x, nearby principle scheduling strategy, really

Step 2061, the first load balancing module are according to the user access request of user x, described first load balancing module
First distribution node server of management obtains the first remaining bandwidth and Baidu tune on described first distribution node server
Degree thresholding.Execution step 2062.
First load balancing module all establishes tune to the distribution node server of described first load balancing module management
Degree resource table, first, this first load balancing module selects described first load balancing module pipe in all scheduling resource tables
The scheduling resource table of the first distribution node server of reason, then, described first load balancing module is according to the use of described user x
Hundred are obtained in the scheduling resource table of the first distribution node server in described first load balancing module management for the family access request
Degree scheduling thresholding on this first distribution node server in the configured bandwidth on this first distribution node server and Baidu,
Again, described first load balancing module obtains current on described first distribution node server of Baidu and has used bandwidth, that is,
There may be other Baidu users before this by described first distribution node server, www.baidu.com to be conducted interviews,
Through occupying a part for the resource to Baidu for the described first distribution node server-assignment, finally, by Baidu described first
Configured bandwidth on the distribution node server and Baidu current difference using bandwidth on described first distribution node server
As the first remaining bandwidth.
Step 2062, the first load balancing module judge whether described first remaining bandwidth is less than or equal to Baidu described
The scheduling thresholding on the first distribution node server of the first load balancing module management in first distribution node.When described
When one remaining bandwidth is less than or equal to scheduling thresholding on described first distribution node server for the Baidu, execution step 2063,
When described first remaining bandwidth is more than scheduling thresholding on described first distribution node server for the Baidu, execution step
2064.
Step 2063, the first load balancing module obtain the second distribution node clothes of described first load balancing module management
The address of business device.
Example it is assumed that Baidu described first load balancing module management the first distribution node server on rent
The bandwidth resources of 10G, scheduling thresholding on this first distribution node server for the Baidu is 2G, if other users of Baidu pass through
Described first distribution node server access www.baidu.com, has occupied what Baidu on this first distribution node server rented
The 8G of bandwidth resources, now, described first remaining bandwidth is 2G, then described first remaining bandwidth is equal to Baidu described first
Scheduling thresholding on distribution node server, therefore, the first load balancing module in described first distribution node is described
It is scheduling according to nearby principle scheduling strategy in the distribution node server of one load balancing module management, specifically, first,
The distance with user x that described first load balancing module obtains described first load balancing module management is negative more than described first
Carry the first distribution node server of balance module management and all distribution node servers of the distance of described user x, then,
Described first load balancing module selects and described user x closest distribution in described all distribution node servers
Node server it is assumed that described first load balancing module management the second distribution node server be with described user x away from
From nearest distribution node server, then using the second distribution node server of described first load balancing module management as warp
