Below in conjunction with specific embodiment, to a kind of processing stream for the method for dispatching more CDN service systems shown in Fig. 2
Journey is described in detail, and content can be as follows：
Step 201：According to default view information and in advance for target domain name configuration in each CDN service system
Domain name is accessed, the analysis request to access domain name under each view is initiated to the authoritative DNS of each CDN service system.
In an implementation, controlling equipment can be based on CNAME technology, configure for each website domain name take in each CDN in advance
Access domain name in business system will be illustrated below with target domain name to refer to website domain name, aiming field for ease of description
Name can be any website domain name.For example, target domain name can be www.xxx.com, then the access that controlling equipment configures for it
Domain name can be www.xxx.com.abc.com, www.xxx.com.def.com, access domain the * abc.com or * of domain name
Def.com is belonging respectively to different CDN service systems.In addition, controlling equipment can store default view information, view is preset
Specific view corresponding to can recorde different IP or IP sections in information, such as Beijing view, Guangdong view, controlling equipment are based on
Default view information can simulate the domain name mapping request under different views, for example, can recorde Beijing in default view information
The a certain dns address of telecommunications be 219.141.136.10, the corresponding view in the address can be Beijing view, Guangdong Telecom certain
One dns address be 202.96.128.86, the corresponding view in the address can be Guangdong view, controlling equipment can simulate by
219.141.136.10 or 202.96.128.86 issues the technical effect of domain name mapping request, regards to simulate in Beijing
Domain name mapping request under figure or Guangdong view.In this way, controlling equipment can be aiming field in conjunction with default view information and in advance
The access domain name in each CDN service system of name configuration, is initiated to the authoritative DNS of each CDN service system to input field
The analysis request of name.
Step 202：The parsing result for carrying the IP address under each view that each CDN service system returns is received,
Monitor the buffer service quality of cache server corresponding to the IP address under each view.
In an implementation, controlling equipment to the authoritative DNS of each CDN service system initiate under each view to access
After domain name mapping request, it can receive what each CDN service system was returned for the domain name mapping request under each view
Parsing result, can carry the IP address under its some corresponding view in each parsing result, which can be with
Corresponding to certain cache server in CDN service system.By taking CDN service system A, CDN service system B as an example, controlling equipment
The access domain name mapping under Beijing view and Guangdong view can be initiated to the respective authority DNS of CDN service system A, B to ask
It asks, after above-mentioned domain name mapping request is completed in the respective authority DNS processing of CDN service system A, B, controlling equipment be can receive
The parsing result for carrying the IP address under the view of Beijing that CDN service system A is returned is with the IP carried under the view of Guangdong
The parsing result for carrying the IP address under the view of Beijing and carry that the parsing result and CDN service system B of location return
The parsing result of IP address under the view of Guangdong.Later, controlling equipment can monitor corresponding to the IP address under each view
The buffer service quality of cache server, and corresponding buffer service data are recorded, as cache responses time, cache contents are hit
Rate and caching cost etc..
Optionally, controlling equipment can predefine cache server to be scheduled, correspondingly, specific processing can be as
Under：According to the buffer service quality of cache server corresponding to the IP address under each view of monitoring, predefine each
IP address corresponding to cache server to be scheduled under view.
In an implementation, controlling equipment can be based on corresponding to the IP address under the above-mentioned each view recorded during monitoring
Cache server buffer service data, the IP address institute got under each view that each CDN service system returns is right
The buffer service quality for the cache server answered, then controlling equipment can be to the slow of each cache server under each view
It deposits service quality to analyze and count, finds the top-quality cache server of buffer service under each view, and then dispatch and set
It is standby can be by the top-quality cache server of buffer service under each view, the caching to be scheduled that is determined as under respective view
Server, while determining the corresponding IP address of above-mentioned cache server to be scheduled.
Optionally, controlling equipment can be based on the current caching clothes to be scheduled of continually changing monitoring situation adjustment at any time
Business device, correspondingly, specific processing can be as follows：Every preset period of time according to the monitoring situation of record, each view is redefined
Under IP address corresponding to cache server to be scheduled.
In an implementation, it is contemplated that the buffer service quality of each cache server is dynamic change, therefore, controlling equipment
Can every preset period of time, such as five minutes or ten minutes, redefine under each view cache server to be scheduled and
Its corresponding IP address will currently have preferably cache as much as possible so that controlling equipment can be based on newest monitoring situation
The cache server of service quality is determined as cache server to be scheduled.
Step 203：When receiving the target domain name analysis request to target domain name, target domain name analysis request pair is determined
The target view answered returns to target ip address corresponding to cache server to be scheduled under target view.
In an implementation, when the website that certain user access accelerates by CDN, which can be in the browser of terminal operating
The website domain name (can be described as target domain name) that the website is inputted in application program, may then pass through click access buttons access should
Website.In this way, the domain name mapping that terminal can be initiated to public DNS to above-mentioned target domain name is requested.Later, public DNS can be with
Based on the target domain name, the address of the authoritative DNS in above-mentioned CDN scheduling system is inquired, then public DNS can be to CDN tune
Authoritative DNS in degree system, which initiates the domain name mapping to the target domain name, to be requested.Later, controlling equipment can receive to target
The target domain name analysis request of domain name, IP address or the target domain name analysis request that may then based on public DNS are corresponding
The IP address of terminal carried in data packet, determines the corresponding target view of target domain name analysis request, and then controlling equipment can be with
It gets based on the monitoring situation recorded and the IP address of cache server to be scheduled under target view of determination (can claim
For target ip address), then target ip address can be returned to public DNS by controlling equipment, it should be noted that above-mentioned determination
Cache server to be scheduled be usually the top-quality cache server of buffer service.In this way, public DNS is receiving mesh
Mark IP address after, target ip address can be returned to above-mentioned terminal, then above-mentioned terminal can by target ip address to
Above-mentioned cache server to be scheduled sends access request to obtain web site contents.
It is easily understood that it is preferable that scheduling buffer service quality may be implemented by the processing of above-mentioned steps 201-203
Cache server handles user to the technical effect of the access request of website, in this way, need to only consider each CDN service system
Buffer service quality, without regard to its dns resolution quality, so as to make full use of the caching in each CDN service system
Service, especially DNS service is second-rate and the preferable CDN service system of buffer service quality.
Optionally, if controlling equipment is previously determined the IP address of the cache server to be scheduled under each view,
Then the part processing of step 203 can be as follows：Under predetermined each view corresponding to cache server to be scheduled
In IP address, target ip address corresponding to cache server to be scheduled under target view is searched, and return it into.
In an implementation, the IP of the cache server to be scheduled under each view is previously determined due to controlling equipment
Location, in this way, controlling equipment has been after having determined the corresponding target view of target domain name analysis request, it can be under each view wait adjust
In IP address corresponding to the cache server of degree, the cache server to be scheduled under target view currently determined is found
Corresponding IP address, i.e. target ip address mention so that target ip address directly can be returned to public DNS by controlling equipment
High domain name resolution efficiency.
Optionally, controlling equipment can receive target domain name analysis request and then determine caching clothes to be scheduled
Business device, correspondingly, specific processing can be as follows：According to cache server corresponding to the IP address under the target view of monitoring
Buffer service quality determines target ip address corresponding to cache server to be scheduled under target view, and returns it into.
In an implementation, controlling equipment is with receiving the IP of each CDN service system return carried under each view
After the parsing result of location, only the buffer service quality of cache server corresponding to the IP address under each view can be carried out
Monitoring.In this way, controlling equipment can be only when receiving the target domain name analysis request to target domain name, just according to the mesh of monitoring
The buffer service quality of cache server corresponding to the IP address under view is marked to determine caching to be scheduled under target view
IP address corresponding to server, later, controlling equipment can be by cache server institutes to be scheduled under determining target view
Corresponding IP address returns to public DNS, so as to reduce the system resource utilization rate of controlling equipment.
Optionally, cache server to be scheduled can be determined by calculating the mass fraction of cache server, with true
It sets the goal under view for cache server to be scheduled, correspondingly, specific processing can be as follows：Target view based on monitoring
Under IP address corresponding to cache server buffer service data, calculate target view under each cache server quality
Score；Determine that the highest cache server of mass fraction is cache server to be scheduled under target view, and will be to be scheduled
IP address corresponding to cache server is determined as target ip address.
In an implementation, controlling equipment can monitor the caching clothes of cache server corresponding to the IP address under each view
Business quality, and corresponding buffer service data are recorded, such as the cache responses time in nearly one hour, cache contents hit rate
Deng.In this way, controlling equipment can find each buffer service under target view in all buffer service data of record
Then the buffer service data of device calculate the mass fraction of each cache server under target view, so it is easy to understand that quality
Score is higher, then the buffer service quality of cache server is higher.Later, controlling equipment can be each slow based on what is be calculated
The highest cache server of mass fraction under target view is determined as buffer service to be scheduled by the mass fraction for depositing server
Device, and IP address corresponding to cache server to be scheduled is determined as target ip address.Using target view as Beijing view,
For CDN service system A, CDN service system B, it is assumed that CDN service system A, B respectively returns to an IP address, then controlling equipment can
To receive two IP address, then (caching clothes only can be recorded as respectively to the corresponding cache server of the two IP address
Business device A, cache server B) the cache responses time be monitored, and then controlling equipment can be mono- section to cache server A, B
The all previous cache responses time in time is recorded, and then it is respective average can to calculate cache server A, B for controlling equipment
Cache responses time, the average cache response time can be scaled the mass fraction of cache server, for example, can be to average
The cache responses time is inverted, using obtained numerical value as mass fraction, such as the average cache response time of cache server A, B
Respectively 500 milliseconds, 1000 milliseconds, the then mass fraction to convert are 0.002,0.001, it can be seen that the matter of cache server A
The mass fraction that score is higher than cache server B is measured, therefore controlling equipment can determine the corresponding IP address of cache server A
For target ip address.
Optionally, it is contemplated that each CDN service system can dynamically adjust the corresponding IP address of each cache server
Situation, controlling equipment can periodically initiate access domain name analysis request, correspondingly, specific processing can be as follows：When parsing is tied
When retaining duration more than preset duration of fruit is initiated to the authoritative DNS for the CDN service system for returning to parsing result each again
The analysis request to access domain name under view.
In an implementation, controlling equipment is with receiving the IP of each CDN service system return carried under each view
After the parsing result of location, the duration that retains of each parsing result can be recorded.When some parsing result is when retaining
When length is more than preset duration, such as one day or three days, controlling equipment can be to the authority for the CDN service system for returning to parsing result
DNS re-initiates the analysis request to access domain name under each view, enters domain to obtain each CDN service system docking
The newest parsing result of name thereby may be ensured that the IP address under each view is consistent with practical corresponding cache server.
In the present embodiment, public DNS only need to dispatch system to CDN and initiate domain name analysis request, can be directly obtained
The IP address of the corresponding cache server of the domain name, without obtaining IP address from the CDN service system where cache server,
So as to reduce the dns resolution time, the scheduling quality of CDN scheduling system is improved.In addition, CDN, which dispatches system, is dispatching more CDN
When service system provides CDN service, the buffer service quality of each CDN service system need to be only considered, so as to make full use of
The buffer service of each CDN service system, especially DNS service be second-rate and the preferable CDN service system of buffer service quality
System, and then the scheduling quality of CDN scheduling system can be improved.
