Specific implementation mode
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
As described before, in existing scheme, the access order that user watches video is：VPS->Scheduler->Cache machines A
(downloading the 1st video slicing)->Scheduler->Cache machines B (the 2nd video slicing of download) ... ...
Referring to Fig. 1, schematic diagram is realized for prior art resources accessing control.
Step (1):Client asks fragment address list to VPS；
Step (2):Client access scheduling device obtains the address of 1 corresponding cache machines of fragment；
Step (3):Client carries out fragment 1 according to the address of 1 corresponding cache machines of fragment and downloads；
The download of other each fragments is required for repeating step 2-3 progress.
Wherein, the address in the fragment address list that client is asked from VPS in step 1 is the address of domain name form,
It is to be appreciated that the address of scheduler；Then it is obtained in step 2 from scheduler further according to the address access scheduling device of scheduler
The address of cache machines.
For playing the flow of f4v formatted files, client can obtain a list such as Fig. 2 formats when accessing VPS,
Example in Fig. 2 includes three f4v file fragmentations, and each format is http://data.video.qiyi.com/
videos/...../*.f4v.Later, data.video.qiyi.com can be accessed when each fragment of client downloads,
It is exactly scheduler, goes to the address of inquiry cache machines.Scheduler can give one IP address of client every time, and client is again later
Remove this IP address downloading video files.
The above flow is excessively cumbersome.From the angle of client, if removing some cache machine downloading video files no problem,
So it is not necessarily to which cache machine inquiry scheduler every time should remove；Only speed can not be accessed or download in current cache machines
When spending slow, just need replacing.Another problem is, using above-mentioned flow, when cache machines can connect and scheduler cannot connect
When connecing, video can not also play, this is also unreasonable.
It is a kind of resource access control method flow chart provided in an embodiment of the present invention referring to Fig. 3, this method includes：
S301：Client initiates resource access request to resolution server；
S302：Resolution server returns to carry to client to be believed according to the download address that the addresses ip of download server obtain
The resource access response of breath；
S303：Client is according to carrying out resource downloading in download address information to download server.
Hereinafter, it is illustrated as the example of resolution server, by the example of download server of cache machines using VPS.
Resource includes various Internet communication resources, including but not limited to the resources such as video, picture, word.With video resource
For example, video resource is to be stored in network side with fragment, be played in client with fragment.Therefore one in the embodiment of the present invention
In kind realization method, resource can be understood as video slicing.
Client initiates that in resource access request resource parameters and/or customer parameter can be carried to VPS.By taking video as an example,
Resource parameters include the movie and television play title of viewing, total film size；Customer parameter includes user ip etc..
After VPS receives the resource access request of client, resource access is obtained by resolving resource access request and is asked
The resource parameters and/or customer parameter for asking carrying, then get the ip of cache machines according to resource parameters and/or customer parameter
Address.In a kind of realization method, pass through the addresses ip that access scheduling device obtains cache machines.
Client needs to obtain the corresponding url of resource (Uniform Resource to realize resource downloading
Locator, uniform resource locator).Url includes two parts：A part is download domain name, such as
“data.video.iqiyi.com”；Another part is uri (Uniform Resource Identifier, uniform resource identifier
Symbol), such as：“/videos/..../*.f4v”.Therefore in one implementation, VPS is visited in the resource for receiving client
After asking request, the corresponding uri of resource can also be obtained by searching for database mode.
There are many forms for download address information.
In a kind of optional mode, download address information includes the addresses ip and uri.Namely in such mode, VPS is to obtaining
The addresses ip got and uri are not processed, but will be carried both as download address information and be returned in resource access response
Client.In such mode, client needs after receiving resource access response and obtaining the addresses ip and uri by the addresses ip
The url of resource downloading can be carried out with uri compositions, and resource is finally downloaded from cache machines according to url.
In a kind of optional mode, download address information refers to url.Namely in such mode, VPS is to the ip that gets
Address and uri processing, such as the addresses ip and uri are formed to the url that can carry out resource downloading, and url is carried in resource
Access response returns to client.In such mode, client is after receiving resource access response and obtaining url, directly
Resource is downloaded from cache machines according to url.
Such as preceding introduction, for the different form of download address information, client is according to download address information to cache machines
The upper mode for carrying out resource downloading is also different.The case where including the addresses ip and uri for download address information, client is under
Resource downloading is carried out in set address information to cache machines includes：Resolving resource access response obtains the addresses ip and uri first；So
The addresses ip and uri compositions can be carried out to the url of resource downloading afterwards；Resource is finally downloaded from cache machines according to the url.It is right
In download address information is url the case where, client resolving resource access response obtains url；Then directly according to url from
Resource is downloaded on cache machines.
As it can be seen that scheduler address is supplied to client, client further according to scheduler different from VPS in existing scheme
Location access scheduling device obtains the mode of cache machines address, and the direct access scheduling devices of VPS obtain cache machines in the embodiment of the present invention
Address, and this is supplied to client according to the download address information that cache machines address obtains, client is without each as a result,
It carries out that access scheduling device is all gone to obtain cache machines address when resource downloading, but directly according to the download address information of VPS offers
Resource downloading is carried out to cache machines.When cache machines can connect and scheduler cannot connect, resource will not be influenced
It plays.
In resource access process, the cache machine states in order to ensure current accessed as far as possible are available, and avoid in advance not
The case where carrying out failed download, client can obtain the state of current cache machines with timing request；In addition, in resource access process
In, inevitably it will appear due to the situation that resource downloading caused by network or other reasons fails or speed of download is slow, in order to keep away
Exempt from influence of these situations to resource downloading, client can be made from new cache machines in such a way that cache machines are replaced in control
Carry out resource downloading.
Therefore, in a kind of optional mode, the embodiment of the present invention is in the above two classes situation (timer access；Failed download or
Speed of download is slow) under support client access scheduling device, request scheduling device judge realize need carry out cache machines replacement.
Further include adjusting in order to realize access of the client to scheduler, in the resource access response that VPS is returned to client
Spend device address.
Client proceeds as follows：Client judges whether to meet：Reach preset timer access scheduler moment, nothing
Method carries out the low any one condition of resource downloading, resource downloading speed；If so, client is initiated according to scheduler address to scheduling
The access of device, request scheduling device, which judges to realize, needs replacing download address, if it is desired, then obtains new download address, and presses
Resource is downloaded according to new download address.
Wherein：Client can determine whether failed download or the slow situation of speed of download in the following manner：Visitor
Detect current TCP (Transmission Control Protocol, transmission control protocol) connection or HTTP in family end
(HyperText Transfer Protocol, hypertext transfer protocol) connects, if TCP connection or HTTP connections are obstructed,
Then determination can not carry out resource downloading；And/or detection resource downloading speed, if resource downloading speed plays speed less than resource
Degree is less than speed of download lowest threshold, it is determined that resource downloading speed is low.
In a kind of optional mode, client includes to the access of scheduler according to the initiation of scheduler address：Client root
The scheduling access request of scheduling reference parameter is carried to scheduler dispatches according to scheduler address；Corresponding, scheduler is according to scheduling
Scheduling reference parameter in access request judges whether to need replacing cache machines；If necessary to replace, new cache machines are determined
The new addresses ip；And the scheduling access response for carrying the download address data obtained according to the new addresses ip is returned to client.
In a kind of optional mode, scheduling reference parameter includes that parameter, current cache machines are inquired/replaced to current cache machines
Ip address parameters, and/or, the used ip list parameters of this playing resource；Corresponding, scheduler judgement needs replacing
Cache machines simultaneously determine that the process of the new addresses ip of new cache machines is：Parameter, current is inquired/replaced to scheduler according to cache machines
The ip address parameters of cache machines, and/or, resource plays ip list parameters, the addresses ip of selection and the current cache machines of client
Difference and the not new addresses ip of the new cache machines in the used ip lists of this described playing resource.
As it can be seen that the embodiment of the present invention changes the side for being required for access scheduling device before each downloading video files of existing scheme
Formula, becoming client, whether the existing ip of active inquiry can be used on time.Due to being not necessarily to frequent access scheduling device, flow is simplified, only
Have when current cache machines can not access or speed of download is excessively slow, just needs replacing cache machines.
The example downloaded below with video slicing, from the process of realization, two angles of each scrap build, to resource
Access control method illustrates.
Referring to Fig. 4, for a kind of resource access control method realization schematic diagram provided by one embodiment of the present invention.
Step (1)：Client accesses VPS；
Step (2)：VPS obtains download address to scheduler；
Step (3)：VPS returns to the data constituted comprising the addresses ip and uri to client；
Step (4)：After client constitutes url according to the addresses ip and uri, according to downloading slicing on url to cache machines；
Step (5)：It reaches or can not download or when speed of download is excessively slow in timing, client access scheduling device, request
New download address (new cache machines address), and according to new address from new cache machines downloading slicing (under new cache machines
Carry the process such as step (4) of fragment).
Compared with the prior art, the transformation to existing procedure includes VPS, scheduler and client three to the embodiment of the present invention
Point.Wherein since scheduler transformation is more, can also be related in other two-part descriptions.
VPS is transformed
When client accesses resource at present, the url download address that the lateral user of network returns includes two parts：A part is
Data.video.iqiyi.com, that is, domain name is downloaded, another part is subsequent/videos/..../* .f4v, referred to as
uri.This two parts has collectively constituted a url, for client downloads.
The embodiment of the present invention changes this mode：When client accesses VPS servers, VPS is using existing method
On the basis of obtaining uri, according to the parameter of client request (the movie and television play title, total film size of such as viewing, user ip),
Instead of client access scheduling device, and only access primary, one available download address of acquisition.Later can not by this address ip and
Uri forms url, but returns to client (can also directly constitute url and issue client) directly as a part for format, visitor
The mode that family end assembles url is more flexible.
For example, it is assumed that when client request watches the video of Fig. 2, VPS finds out three uri of the video respectively as schemed
Shown in uri in 2, and the available downloads address that scheduler provides is 180.153.129.205, then VPS returns to following information
To client：
{ (180.153.129.205 ,/videos/v0/20160802/56/26/
8bc193dd86d1fccd9a2d030bbae8082d.f4v), (180.153.129.205 ,/videos/v0/20160802/
56/26/9a4df444b7d8b2461d976e58405cd745.f4v), (180.153.129.205 ,/videos/v0/
20160802/56/26/dfb17e97e07aeb7c3d8c8001f3188ba3.f4v)}。
After client receives this message, voluntarily constitutes url and be downloaded.
Two, client is transformed
What client transformation can be completed by rewriting program code, it is desirable to be able to add following functions：
1, the addresses ip for the video cache machines used that start broadcasting can be obtained from VPS and the video content watched
Uri can connect the addresses ip with the url that uri compositions can be downloaded；
2, it is able to access that scheduler.When access scheduling device, three parameters can be carried, it is (right to be referred to as type in this example
Answer " current cache machines inquire/replace parameter " above-mentioned), the current addresses the ip (corresponding " addresses ip of current cache machines above-mentioned
Parameter "), used ip lists (corresponding " the used ip lists ginseng of this playing resource above-mentioned in this watching process
Number ").Wherein type may include two values：0 and 1, it respectively represents " whether still available inquiring current cache machines ip " and " wants
It asks and replaces cache machines ip ".The value that the current addresses ip watch used ip lists with this is as its literal meaning.
3, the opportunity of access scheduling device.Access scheduling device in both cases：(1) timer access, i.e., each a period of time
(e.g., 5 seconds) access a scheduler, and type values at this time are 0, that is, represent to scheduler and inquire that " whether is current cache machines ip
Still available ".(2) it is 1 to access type values at this time when speed of download is excessively slow or the failure that can not be accessed occurs, represent " it is required that
Scheduler replaces an available ip ".It can not access that can be regarded as network connection obstructed, such as TCP connection or HTTP connections are not
It is logical；Speed of download can judge excessively by client slowly, if for example, the speed for downloading file is slower than the broadcasting speed of video, it can be with
Think that speed of download is excessively slow.
4, returning the result for scheduler can be received, and new url is formed according to the IP address that scheduler returns and is carried out down
It carries.
Three, scheduler is transformed
1, scheduler can support VPS to ask, and return to corresponding IP results according to the request of VPS and record corresponding number
According to carry out load balancing (content of load balancing mode non-present invention embodiment discussion).
2, scheduler can support the access of client.When client accesses parameter type=1, can return and client
The cache for holding currently used IP different and being different from the IP in used IP lists in client this watching process
Machine IP address.
3, can the cache machines IP that client uses actively be replaced according to the situation of cache generator terminals.For the visit of client
Ask the request of parameter type=0, returning the result for scheduler may include at least two parameters：Status (state) and ip.
Status can select 0 or 1, respectively represent " the cache machines that client uses are out of question, without change " and " this cache machine
IP is problematic, replaces "；As status=1, IP parameter values are the cache machines for the downloading video files that client needs replacing
Address, when status=0, IP parameter values are null value.
Communication mode between the above VPS, scheduler and client needs for communication mode (such as side https of safety
Formula), prevent parameter to be tampered in transmission process.
It should be noted that for embodiment of the method, for simple description, therefore it is all expressed as a series of action group
It closes, but those skilled in the art should understand that, the embodiment of the present invention is not limited by the described action sequence, because according to
According to the embodiment of the present invention, certain steps can be performed in other orders or simultaneously.Secondly, those skilled in the art also should
