Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention
Embodiment be described in detail.It should be noted that in the absence of conflict, in the embodiment and embodiment in the application
Feature can mutual any combination.
Acceleration system is broadcast live when terminal passes through browse request index file in CDN, can preheat URL in index file simultaneously
Whole TS files of list, to accelerate to play.
In the HLS playing process of the relevant technologies, terminal, should first to the index file in the streaming media server request source HLS
In the url list of index file, each URL is directed toward a playable slice file；Streaming media server will be under index file
After issuing terminal, terminal requests slice file according to the sequence of URL in url list one by one, and slice file is carried in request
URL, streaming media server obtain corresponding slice file from source station according to the URL and return to terminal.
One of the difference of HLS live streaming and program request is the length of index file: in HLS live streaming, an index file is only wrapped
URL containing several TS files；And in HLS program request, an index file includes the URL of hundreds and thousands of a TS files.If with
Family only plays one of TS file, and CDN program request acceleration system preheats other all TS slices simultaneously, will cause very big
Flow waste.Thus need to find a kind of method for efficiently controlling pre- heat flow.
Embodiment one
The present embodiment is related to a kind of method for processing resource and device, by adding pre- heat label in the URL of indexed file
It indicates to need the slice file that preheats, for realizing the control of pre- heat flow.
By taking the program request acceleration system based on HLS as an example, the program request acceleration system can be set as CDN the present embodiment
In the streaming media server of node.When user passes through a certain multimedia file of terminal on demand (such as video file), terminal can be requested
The index file of the multimedia file, after program request acceleration system receives end to the request of the index file, if it is determined that not
The index file is cached, the index file can be obtained from source station, then this resource is added preheating to index file
The processing of label.
As shown in Figure 1, the method for processing resource of the present embodiment program request acceleration system includes:
Step 110, it selects to add from the uniform resource position mark URL list for the slice file that index file includes pre-
The URL of heat label；
In the present embodiment, the selection from the url list for the slice file that index file includes will add pre- heat label
URL, comprising: in the url list according to setting interval select URL, as the URL that add pre- heat label.It is described
The interval of setting can be indicated with the number of URL, namely select a URL to add pre- heat label every N number of URL, and N is nature
Number.When N is larger, the URL added after pre- heat label can be longer, while the slice file preheated is more, and when N is smaller, preheating
Slice file it is less, thus be contemplated that these because usually selection N value.In one example, N is set as 1 value in 1-10.
And when N is set as 0, it is that pre- heat label is added to each URL.In addition, the interval of the setting is not required for each
Every all must be the same, to the URL on the different broadcasting periods, different interval selection URL can be used.
It can also be indicated with the playing duration of the corresponding slice file of URL at the interval of another embodiment, the setting, example
Such as, after adding pre- heat label for a URL in url list, by the corresponding playing duration for being sliced file of its subsequent URL
It adds up one by one, when cumulative duration meets or exceeds the playing duration of setting, the last one URL of reselection addition preheating mark
Note.Playing duration as setting interval can consider in conjunction with the playing duration for being sliced file, for example, if each TS can be broadcast
10s is put, then preheating a 1-2 can；If each TS can only play 2s, that needs more preheatings several, such as 5-10,
It is equivalent to the time for reserving one section of buffering.
Step 120, pre- heat label is added respectively for the URL of selection, the pre- heat label includes need to preheat one
The address information of a or multiple slice files.
This step is after the URL of selection adds pre- heat label respectively, which is modified.The modification
The URL with pre- heat label being not present before including in the url list of index file afterwards, if the interval of setting is not 0,
It further include original URL without pre- heat label in the url list.Program request acceleration system completes the above-mentioned place to index file
After reason, the index file is sent to the terminal and caches the index file.The subsequent terminal that receives again is to the index
When the request of file, the index file duplication portion of caching can be directly sent to the terminal of request.
In the present embodiment, the address information in the pre- heat label is URL namely the pre- heat label includes the needs
The URL of the one or more slice files preheated.Program request acceleration system according to the URL in pre- heat label can directly from
Source station gets corresponding slice file and is put into caching, to realize preheating.But the application is not limited to this, in another implementation
In example, described address information not instead of URL itself, the index information of URL, the index information needs to carry out pre- for lookup
The URL of one or more slice files of heat.
In this application, preheating is to obtain the slice file not played and be put into caching, thus pre- heat label includes
The address information for the one or more slice files for needing to preheat is necessarily after the corresponding slice file of URL where pre- heat label
One or more slice files address informations.And in the present embodiment, to any pre- heat label, address information packet therein
First URL after URL where including the pre- heat label (namely the pre- heat label be added to URL) will be added to next
Between the URL of pre- heat label all URL (including after URL where pre- heat label first URL and it is next to add it is pre-
The URL of heat label).In one example, it selects URL to add pre- heat label by interval of 3 URL, then to add in url list
Adding the URL of pre- heat label is the 1st URL, the 4th URL, the 7th URL ... ..., and so on.So, add in the 1st URL
The pre- heat label added includes the 2-4 URL (namely the 2-4 URL for being sliced file), and program request acceleration system receives terminal to the
After the request of 1 slice file, so that it may the pre- heat label in the 1st URL is parsed, according to the 2-4 URL therein from source station
It obtains the 2-4 slice file and is stored in caching, that is, complete the pre-heat treatment for being sliced file to the 2-4, program request acceleration system
After terminal is received to the request of the 2nd, the 3rd and the 4th slice file, it can directly find from caching and cut accordingly
Piece file simultaneously returns to terminal, to achieve the effect that acceleration.Similarly, the pre- heat label added in the 4th URL includes 5-
7 URL can make program request acceleration system after receiving terminal to the request of the 4th slice file, complete to cut 5-7
The pre-heat treatment of piece file, and so on.Using this labeling method, in addition to the slice file that first is requested, other slices
File can be preheated, thus have good preheating acceleration effect.Certainly, for the application, if limited by resource
System, can also be by the portion between first URL to next URL that add pre- heat label after URL where pre- heat label
URL is divided to be added in the pre- heat label.
In the present embodiment, the pre- heat label can be added in the domain name of URL, or be added in the path of URL, or
Person is added in the parameter of URL.Wherein, be added in the domain name of URL include be added to before the domain name of URL, below or in
Between, the path for being added to URL neutralize be added in the parameter of URL be also in this way,
One explanation is done to the addition of pre- heat label with an example below.Assuming that primary index file is m3u8, m3u8
Content format there are many, it is assumed that m3u8 file be test.com/x/1.m3u8, if the content of every row shaped like
Test.com/1.ts, then player can request test.com/1.ts next time；If every row content is shaped like 1.ts, under player
It is secondary to request test.com/x/1.ts；If every row content can request test.com/ shaped like/1.ts, player next time
1.ts.In this example, it is assumed that the entitled test.com/1.m3u8 of m3u8 file, preceding 3 TS slice of url list
URL are as follows:
1.ts
2.ts
3.ts
It is divided into 2 URL between the setting that selection uses when adding the URL of pre- heat label, in this example, selection adds 1.ts
Add pre- heat label, then needing in the pre- heat label added for 1.ts comprising 2.ts and 3.ts.
If pre- heat label is added in the domain name of URL, modified index file includes:
2.ts.3.ts.test.com/1.ts
test.com/2.ts
test.com/3.ts
When carrying 2.ts.3.ts.test.com/1.ts in the request that program request acceleration system receives, 2.ts is just preheated simultaneously
And 3.ts.
If pre- heat label is added in the path of URL, modified index file includes:
/2.ts/3.ts/1.ts
/2.ts
/3.ts
In the request that program request acceleration system receives when carrying/2.ts/3.ts/1.ts, 2.ts and 3.ts are just preheated simultaneously.
If pre- heat label is added in the parameter of url, modified index file includes:
1.ts? next=2.ts, 3.ts
2.ts
3.ts
1.ts is carried in the request that program request acceleration system receives? when next=2.ts, 3.ts, just simultaneously preheat 2.ts and
3.ts。
For be sliced file URL add pre- heat label mode be not limited to it is above several, as long as appointing addition
Position and format can be parsed pre- heat label and URL respectively by the position of agreement and format.
Correspondingly, the present embodiment additionally provides a kind of resource processing unit, as shown in Figure 2, comprising:
Selecting module 10, for being selected from the uniform resource position mark URL list for the slice file that index file includes
