Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Content delivery network service switching method provided by the present application, can be applicable in the application environment such as Fig. 1, wherein
Client is communicated by network with server.Wherein, client can be, but not limited to various personal computers, notebook electricity
Brain, smart phone, tablet computer and portable wearable device.Server can use the either multiple services of independent server
The server cluster of device composition is realized.
In one embodiment, it as shown in Fig. 2, providing a kind of content delivery network service switching method, applies in this way
It is illustrated, may include steps of for client in Fig. 1:
S101, the first designated domain name of access, the first designated domain name access have the first CDN service provider to provide
CDN service；
It is understood that client accesses the first designated domain name, first designated domain name is that access has the first CDN clothes
The CDN service that business provider provides, primarily to allowing the client that the CDN service can be used carries out acceleration service,
Improve the access speed to first designated domain name.Specifically, first designated domain name can access CDN service in advance,
When the client accesses first designated domain name, i.e., the described client is asked to the first designated domain name server sending
When asking, the CDN service that first CDN service provider provides can be with the content of the first designated domain name described in accelerated loading.Than
Such as, client accesses first shopping website, which has accessed the CDN service of the first CDN service provider offer,
So the CDN service that first service provider provides can be with the content of first shopping website of accelerated loading.
If the number of the failure of the first designated domain name described in S102, connected reference reaches preset threshold, access second is changed
Designated domain name, the CDN service that the second designated domain name access has the second CDN service provider to provide, and described second is specified
The content that domain name is distributed in CDN service is identical as the content that first designated domain name is distributed in CDN service.
It is understood that content and first designated domain name that second designated domain name is distributed in CDN service
The content distributed in CDN service is identical, this allows for the client and accesses the content and visit got after the second designated domain name
Ask content that the first designated domain name is got be it is the same, difference therein out will not be discovered using the user of the client, from
And the switching of CDN service can be completed in the case where not affecting user experience.Specifically, if the client is continuously visited
Ask that the number of the first designated domain name failure reaches preset threshold, it may be considered that first CDN service provider provides
CDN service there are failures, at this time, the client can pass through change and access second designated domain name, i.e., the described visitor
Family end issues access request to the second designated domain name server, and the CDN service that second CDN service provider provides can
With the content of the second designated domain name described in accelerated loading.For example, the number of first shopping website of connected reference failure reaches
Preset 3 times, first shopping website is the CDN service for having the first CDN service provider of access to provide, at this point, in order to allow visitor
Family end access domain name can still enjoy the acceleration of CDN service, and client can be arrived by changing the domain name of the first shopping website
Spare domain name, the spare domain name are the spare domain names of first shopping website, and with the content of first shopping website being
, accessed the second CDN service provider offer CDN service, thus client access first shopping website not at
The number of function reaches 3 times of preset times, can also benefit from CDN service and accelerates to access the service of identical content.
Further, before change accesses the second designated domain name, cause to visit to exclude described this earth fault of client
It asks domain name unsuccessful situation, needs to judge local network connection, as shown in figure 3, can also include as follows
Step:
The test domain name of S201, access preset, the test domain name can be accessed normally；
If testing domain name described in S202, successful access, the number of the failure of the first designated domain name described in connected reference is detected
Whether preset threshold is reached；
If S203, the access test domain name failure, issue the warning message about this earth fault of client；
If the number of the failure of the first designated domain name described in S204, connected reference does not reach preset threshold, described in access
First designated domain name.
For step S201, first designated domain name may be led to institute by the interference of described this earth fault of client
It states client and accesses that first designated domain name is unsuccessful, the CDN service that first CDN service provider provides can be described
Client is mistakenly considered problematic.In a particular embodiment, the domain name that can be normally accessed, the client access preset are preset
Test domain name.For example, presetting a shopping website that can be normally accessed, client can be visited the shopping website
It asks.
For step S202, it is to be understood that above-mentioned test domain name refers to be used to test local network connection
The domain name of situation, and can normally be accessed by the client.Exclude described this earth fault of client cause access domain name not at
The case where function.Specifically, if testing domain name described in the client successful access, illustrate that the local network connection of client does not have
Problematic, then whether the number for detecting the failure of the first designated domain name described in the client connected reference reaches preset threshold.Than
Such as, client access is a shopping website, and client can first attempt the content that access obtains the shopping website, if can visit
It asks the content for getting the shopping website, then illustrates not going wrong for local network connection.
For step S203, the warning message can be warning word, letter or sending sound etc., be embodied
In example, if the client accesses the test domain name failure, illustrate that the client local network connection is bad, then
The client issues the warning message about described this earth fault of client.For example, client access is a shopping network
It stands, client cannot get the content on shopping website, then illustrate that the connection of local network there is a problem, Ke Yi
Content shows the words such as letter error (mistake) or Chinese display " webpage loss " on webpage.
For step S204, in a particular embodiment, if the number of the failure of the first designated domain name described in connected reference does not have
Reach preset threshold, illustrates that the CDN service that first CDN service provider provides is normally that then the client can
To continue to access first designated domain name.For example, the number of first shopping website of connected reference failure has not reached pre-
If 3 times, first shopping website be have access the first CDN service provider provide CDN service, then client can continue
Access the shopping website.
Further, before change accesses the second designated domain name, in order to allow client that can get fast response time
The high spare domain name with stability reduces the switching between CDN service, needs to carry out priority to each spare domain name
It distinguishes, as described in Figure 4, this method can also include the following steps:
S301, preset each spare domain name is obtained, each backup domain name has been respectively connected to different CDN services and provides
The CDN service that quotient provides；
S302, the priority for obtaining each spare domain name；
S303, determine the backup domain name of highest priority in each spare domain name as the second designated domain name.
For step S301, above-mentioned spare domain name refers to multiple domain names identical with the first designated domain name content,
Multiple spare domain names are set, and each backup domain name is respectively connected to the CDN clothes that different CDN service providers provide
Business, be in order to guarantee the client first domain name access failure number reach preset times when, the visitor
Family end can change domain name of the backup domain name as next access automatically, and have corresponding CDN service provider
The CDN service of offer carries out acceleration service to the domain name.Specifically, the client can preset multiple spare domain names, work as institute
State the access of the first designated domain name it is unsuccessful when, at this time, the spare domain name can be come out by automatic change, multiple described
Spare domain name just has multiple selections, can improve the success rate for getting content, and user demand is guaranteed.For example, being equipped with standby
With domain name A, spare domain name B and spare domain name C, then the CDN service that the first CDN service provider can be provided, the 2nd CDN take
The CDN service that the CDN service and third CDN service provider that business provider provides provide is respectively connected to spare domain name A, spare
Domain name B and spare domain name C, i.e., each different CDN services can accelerate different spare domain names, and client could obtain out these
Spare domain name carries out the deciding grade and level of priority to next step.
For step S302, it is to be understood that in a particular embodiment, the client is can be according to presetting
Priority rule all spare domain names are carried out with the division of priority, the client can just identify obtain it is each
The priority of the spare domain name.For example, being equipped with spare domain name A, spare domain name B and spare domain name C, it may be predetermined that judgement
The rule of each backup domain name priority, according to priority rule can to spare domain name A, spare domain name B and spare domain name C into
Row deciding grade and level, client, which can just identify, gets the corresponding priority of each spare domain name.
For step S303, it is to be understood that in a particular embodiment, the client can first predefine judgement
The rule of each backup domain name priority carries out the deciding grade and level of priority to each spare domain name, can also pass through hand
The mode of dynamic setting carries out the deciding grade and level of priority to each spare domain name.It is determined from each spare domain name described
The spare domain name of highest priority, the spare domain name of this highest priority are intended for the second designated domain name and go to described
Client is changed automatically, so that it is guaranteed that providing CDN service there are also the CDN service quotient carries out acceleration service to domain name.Than
Such as, it is equipped with spare domain name A, spare domain name B and spare domain name C, the grade of manual setting is respectively level-one, second level and three-level,
Middle three-level is greater than second level, second level is greater than level-one, then spare domain name C is the spare domain name of highest priority, i.e., spare domain name C can be with
As the second designated domain name.
Further, the priority of each spare domain name can first pass through the sound for testing each spare domain name in advance
Speed is answered to define the level, as described in Figure 5, before the priority for obtaining each spare domain name, the method also includes:
S401, access to each spare domain name test, obtains each spare domain name when access test
Response speed；
S402, the priority that each spare domain name is determined according to the response speed of each spare domain name, wherein
Response speed is faster, then priority is higher.
For step S401, it is to be understood that for the available fast response time to each spare domain name
Slowly, specifically, test access can be carried out to each spare domain name, the client can be by advance with each described
The CDN service that spare domain name respectively accesses carries out acceleration access to each spare domain name respectively.It is then possible to obtain and remember
The response time length of each spare domain name is recorded, length of time determines each spare dns response speed according to response
The speed of degree.For example, being equipped with spare domain name A, spare domain name B and spare domain name C, is loaded access by client respectively, client
The response time for recording each spare domain name is 1s, 2s, 3s, it may be considered that the response speed of spare domain name A is most fast, spare
The response speed of domain name B is taken second place, the response speed of spare domain name C is minimum, and client can get each spare domain name
Response speed.
For step S402, it is to be understood that the priority is can be determined by the response speed,
Wherein, the response speed is faster, then the priority is higher, and when the speed of the response speed can be by the response
Between length determine that the response time is shorter, then the response speed is faster.The speed of the response speed can also lead to
The form that the server response time Digital size is defined as text is crossed, it finally can be by way of text to each
The priority of the spare domain name is defined the level.For example, being equipped with spare domain name A, spare domain name B and spare domain name C, three spare
The response speed of domain name can be showed by the length of the response time tested out with written form as fast, neutralization
Slowly, spare domain name A, spare domain name B and spare domain name C priority are respectively three-level, second level and level-one, then three-level is greater than two
Grade, second level are greater than level-one, i.e., spare domain name A highest priority, spare domain name B priority takes second place, spare domain name C priority most
It is low.If encountering the response time the same two or more spare domain names, i.e. priority is the same spare domain name,
It may be considered that it is feasible that the client, which arbitrarily distributes the backup domain name as second designated domain name,.Cause
This, the client can be randomly assigned the priority of the response time the same spare domain name.For example, being equipped with spare
Domain name A, spare domain name B and spare domain name C, the response time of three spare domain names be it is the same, at this time, client can be random
Distribute that spare domain name A is highest priority, spare domain name B is that take second place priority, spare domain name C is lowest priority.
Further, the priority of each spare domain name can also first pass through each spare domain name of test in advance
The height of stability is defined the level, as described in Figure 6, before the priority for obtaining each spare domain name, the method
Further include:
S501, access to each spare domain name test, obtains each spare domain name when access test
Packet loss；
S502, the priority that each spare domain name is determined according to the packet loss of each spare domain name, wherein lose
Packet rate is smaller, then priority is higher.
For step S501, it is to be understood that for the size of the packet loss of available each spare domain name,
It specifically, can be with when the CDN service that the CDN service quotient using each spare domain name provides accelerate access
The number for obtaining and recording the loss quantity of each spare domain name content-data packet, according to the spare domain name content-data
The number of the loss quantity of packet calculates the packet loss of each spare domain name.In general, the content of load may
By other influences such as network fluctuations, the case where partial content data packet or full content data packet are likely to occur loss.Than
Such as, client accesses the spare domain name and the data packet requested is 100, but due to network fluctuation problem, finally gets
Data packet only has 90, this just illustrates that the phenomenon that data-bag lost, packet loss 10% occurs in the spare domain name；For another example, if
There are spare domain name A, spare domain name B, is loaded by client obtain content respectively, the data packet of spare domain name A request is 100,
The data finally obtained are surrounded by 100, and spare domain name A packet loss is 0, the data packet of spare domain name B request is 100, finally
The data packet got only has 90, and spare domain name B packet loss is 10%.
For step S502, it is to be understood that in the present embodiment, the priority of spare domain name can pass through the packet loss
For rate come what is determined, the packet loss is smaller, then the priority is higher, and the packet loss also can reflect out the stability,
The packet loss is smaller, then the stability is higher, i.e., the described stability is high, and the priority is also high.The stability
Height can be by way of the server packet loss size be defined as text.It finally can be by way of text pair
The priority of each spare domain name is defined the level.For example, it is equipped with spare domain name A, spare domain name B and spare domain name C, three
The stability of spare domain name can show by the packet loss size of record with written form as stabilization, it is relatively steady and
Surely, spare domain name A, spare domain name B and spare domain name C priority are respectively three-level, second level and level-one, then three-level is greater than two
Grade, second level are greater than level-one, i.e., spare domain name A highest priority, spare domain name B priority takes second place, spare domain name C priority most
It is low.If encountering the same two or more spare domain name of the packet loss, i.e. priority is the same spare domain name, institute
State the priority that client can arbitrarily be randomly assigned the same two or more spare domain name of the packet loss.For example, setting
There are spare domain name A, spare domain name B and spare domain name C, the packet loss size of three spare domain names is the same, and at this time, client can
It is to take second place priority, spare domain name C for lowest priority to distribute spare domain name A as highest priority, spare domain name B.
In conclusion client access first refers to first above provide a kind of content delivery network service switching method
Localization name, the CDN service that the first designated domain name access has the first CDN service provider to provide；Finally, if the client
The number of the failure of first designated domain name described in connected reference reaches preset threshold, then client change second specified domain of access
Name, the CDN service that the second designated domain name access has the second CDN service provider to provide, and second designated domain name exists
The content distributed in CDN service is identical as the content that first designated domain name is distributed in CDN service.As it can be seen that the present invention is real
Show through change domain name and the CDN service of CDN service provider offer is provided, has avoided first CDN service provider and mention
When something goes wrong, user accesses domain name and the case where access failure occurs the CDN service of confession, is conducive to improve user experience and advantageous
In enterprise to the normal operation of domain name.
