Embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field
The every other embodiment that those of ordinary skill is obtained without making creative work, belongs to protection of the present invention
Range.
It is shown in Figure 2, a kind of reality of server node method of adjustment in the CDN network provided by the embodiment of the present invention
Flow chart is applied, this method may comprise steps of：
S110 monitors the transmission rate of the currently used server node of the terminal at terminal access targeted website.
The currently used server node is active node.
During user using terminal access target website, the currently used server node of the terminal is active section
Point.To ensure to provide preferable data transport service to the user, the client monitors terminal by running on the terminal is needed
The transmission rate of currently used server node, and judge whether currently used server node meets preset adjustment and want
It asks, i.e., whether its transmission rate has reached preset adjustment requirement.If not reaching preset adjustment requirement, it may be considered that
The operating status of currently used server node is good, can provide preferable data transport service to the user, not interfere with
The normal use of user；If having reached preset adjustment requirement, it may be considered that currently used server node runs shape
State is bad, can influence the normal use of user, in such a case, it is possible to further execute the operation of step S120.
In practical applications, client can periodically monitor the transmission speed of the currently used server node of the terminal
Rate, you can to currently used server node periodically test the speed, such as carried out every 5 seconds once, often test primary obtain
To a transmission rate.In a kind of specific implementation mode of the present invention, a momentary rate threshold value can be preset, transmission is worked as
Rate is considered as meeting preset adjustment requirement when being less than preset momentary rate threshold value；Alternatively, considering transmission rate
Momentary fluctuation is might have, a number threshold value can be preset again, when transmission rate is continuously less than preset momentary rate door
Limit value and while having reached preset number threshold value is thought to meet preset adjustment requirement；Again alternatively, whithin a period of time (such as
In 30 seconds), if the average transmission rate of currently used server node is less than preset Mean Speed threshold value, then it is assumed that
Meet preset adjustment requirement.Certainly, these threshold values can be set and be adjusted as the case may be, and the present invention is to this
It is not limited.
S120, in the case where the currently used server node meets preset adjustment requirement, from predefine
Standby server set of node in selection one transmission rate higher than the currently used server node transmission rate
Standby server node.
From CDN network structural schematic diagram shown in Fig. 1 it is found that there are multiple services in CDN network corresponding to targeted website
Device node, in addition to currently used server node, other server nodes can be used as standby server node.In general,
Server node in CDN network is safeguarded by CDN service quotient, when user carries out targeted website access by terminal,
The client run in the terminal can know that the node of server node used in corresponding terminal is believed by domain name mapping
Breath, but the nodal information for all server nodes that CDN network is configured can not be obtained, and acquisition CDN nets as much as possible
The nodal information of server node is beneficial to further carry out node adjustment in network.
In a kind of specific implementation mode of the present invention, standby server set of node can be determined by following steps：
Step 1：The available server node listing of the corresponding CDN network in the targeted website is obtained from cloud server,
The available server node listing is that the cloud server collects the summarized results for reporting information of multiple terminals, it is described on
Breath of notifying is each terminal used server node information when accessing the targeted website；
Step 2：According to preset first screening conditions, to the available server in the available server node listing
Node is screened；
Step 3：The set of the server node filtered out is determined as standby server set of node.
For convenience of description, above three step is combined and is illustrated.
In practical applications, for each terminal at access target website, the corresponding CDN network in targeted website can be each whole
One server node of end distribution, can be referred to as available server node, the client run in terminal passes through domain name mapping
The nodal information of available server node used in the terminal can be obtained.Including at least server node in nodal information
Address identifies, and an address mark can be with unique identification a to server node.
If a certain user will access booking website by certain terminal, by taking railway booking website as an example, which can browse
Kyfw.12306.cn is inputted in device client, which parses domain-name information input by user, is somebody's turn to do after parsing
The address of the currently used server node of terminal is identified as 124.126.126.109, it is, of course, also possible to which obtaining currently is made
The other information of server node, such as transmission rate, place telecommunication line, region information, the client are near
The nodal information for including less address mark reports to cloud server.
Foregoing description is carried out from any client angle, and any client all can get respective by identical step
The nodal information of the currently used server node of counterpart terminal, and respectively report the nodal information of these server nodes
To cloud server, cloud server summarizes the nodal information of these server nodes, you can obtains targeted website pair
The available server node listing for the CDN network answered, and the list is safeguarded.That is, beyond the clouds can in server
To store available server node listing, wherein each terminal reported comprising multiple client (i.e. terminal) is in access target website
When used server node information.
It is understood that different terminals region or place telecommunication line may be different so that assigned service
Device node may be different.In this way, as each client constantly reports the node of server node used in its counterpart terminal to believe
It ceases, the available server number of nodes recorded in the available server node listing that cloud server is safeguarded is more and more, most
The most or all of nodal information for the server node that the corresponding CDN network in targeted website is disposed is obtained at last.
In practical applications, a CDN network might have thousands of a server nodes, it is contemplated that the processing capacity of terminal
It can be according to actual conditions, from available server when there is user by terminal access targeted website with the quality level of each node
Selected section or whole server node be as standby server node in node listing, it is selected go out standby server node
Set be standby server set of node.
It is understood that there are the horizontal lower server node of part mass in the available server node listing,
And it regard whole server nodes in available server node listing as standby server node, it will lead to active service
The average quality level of device set of node reduces, and is the clothes of circuit of matching farther out or not from terminal region for some
Business device node, even if being used for terminal, the access speed to improving terminal does not have any help.So can be according to preset first
The server section that screening conditions are screened the available server node in available server node listing, and will be filtered out
The set of point is determined as standby server set of node.
In a kind of specific implementation mode of the present invention, above-mentioned steps two may comprise steps of：
Test the transmission rate of the server node in the available server node listing obtained；
According to test result, the server node for meeting preset condition is filtered out.
After client obtains available server node listing, the transmission rate of available server node therein, root are tested
According to test result, the server node that transmission rate is higher than a certain predetermined threshold value is filtered out, or right according to the height of transmission rate
Server node is ranked up, and filters out the server node of predetermined number.
In view of client test the speed meeting than relatively time-consuming, so server institute beyond the clouds to all available server nodes
The case where can also including the information of transmission rate of each available server node in the available server node listing of maintenance
Under, client can refer to transmission rate therein, be carried out to the server node in available server node listing primary first
Step screening, with ensure test transmission rate in next step operation will not because of available server node quantity it is excessive and excessively consume
When.It is understood that a preliminary screening operation can also be carried out by cloud server, cloud server receives multiple terminals
After the nodal information reported, according to the height of transmission rate in nodal information, transmission rate is higher than to the service of some preset value
Device node screens, and using the server node gone out by a preliminary screening as the available server node of CDN network
Client is returned to, also mitigates the pressure of client in this way.
After a preliminary screening, the transmission rate for the available server node that test screen goes out, according to test result,
Since the highest available server node of transmission rate, the server node of not more than predetermined number is filtered out, such as default
Number is 50, then the server node number finally filtered out is no more than 50.Predetermined number can be set according to actual conditions
It sets and adjusts, if predetermined number is too low to may result in client when carrying out node adjustment in standby server set of node
Number of nodes is very little, if the excessively high equally possible average quality level that can lead to the node in standby server set of node compared with
It is low.
In another specific implementation mode of the present invention, standby server set of node can be determined by following steps：
The standby server set of node of the CDN network corresponding to the targeted website is obtained from cloud server, it is described standby
It is CDN net of the cloud server according to preset second screening conditions corresponding to the targeted website with server node collection
The set of the server node filtered out in the available server node listing of network.
Under normal circumstances, the processing capacity of cloud server can be higher than the processing capacity of terminal, can be by cloud server
According to preset second screening conditions, the available server node in the available server node listing of maintenance is screened,
And the server node filtered out is returned into client, as standby server set of node.
For example, each terminal is reported in the nodal information of the currently used available server node of cloud server includes
The information such as transmission rate, region, place telecommunication line, client is by its counterpart terminal region and place telecommunication line
It is sent to cloud server, cloud server can filter out corresponding available server node conduct according to these information
Standby server node feeding back is to client.
Server screens the server node in available server node listing beyond the clouds, processing speed faster,
The pressure of client can also be mitigated.
During monitoring the transmission rate of currently used server node in step S110, if currently used service
The transmission rate of device node meets preset adjustment requirement, it may be considered that the server node operating status is bad, influences to use
The normal use at family.Concrete reason may be that the load pressure of currently used server node is larger or the server
Telecommunication line where telecommunication line and terminal where node mismatches or hardware fault has occurred in the server node
Deng.In such a case, it is possible to test the speed to the standby server node in predetermined standby server set of node, and
Standby server node of one transmission rate of selection higher than the transmission rate of currently used server node.Here, for
The selection of the standby server node can also can preferentially select transmission rate highest according to result random selection of testing the speed.
S130：Selected standby server node is adjusted to active node.
Having selected a transmission rate to be higher than currently from predetermined standby server set of node in step S120 makes
The standby server node is adjusted to active node by the standby server node of the transmission rate of server node, by
The server node provides corresponding data transport service for the terminal.
The technical solution provided using the embodiment of the present invention, at terminal access targeted website, by monitoring the terminal
The transmission rate of currently used server node knows the actual transmissions situation of server node used in the terminal, such as
The currently used server node of fruit meets preset adjustment requirement, then is selected from predetermined standby server set of node
One transmission rate higher than the transmission rate of currently used server node standby server node, and by the active service
Device node is adjusted to active node, provides corresponding data transport service to the user, improves the access speed of user, is user
Provide better online experience.
Shown in Figure 3, in another embodiment of the present invention, step S120 may comprise steps of：
S121, in the case where the currently used server node meets preset adjustment requirement, from predefine
Standby server set of node in select a server node as active node to be selected；
Whether S122 judges the transmission rate of the active node to be selected higher than the currently used server node
Otherwise transmission rate, executes step S123 if so, thening follow the steps S130；
S123 selects a server for not being selected as active node to be selected from the standby server node obtained
Node repeats step S122 as active node to be selected.
It, can be successively by the transmission rate of the server node in standby server set of node by the execution of above step
It is compared with the transmission rate of currently used server node, one transmission rate of final choice is higher than currently used
The standby server node of the transmission rate of server node, and it is adjusted to active node.
