Embodiment
For reducing the consumption of resource, promote the execution efficient of flow process, the embodiment of the invention provides a kind of link task processing method, be used for carrying out first when downloading the link task that flow process comprises, the link task is handled, and concrete treatment scheme comprises as shown in Figure 3:
The duplicate node achievement of step 302, multiplexing this link task;
Next link task that flow process comprises is downloaded in step 303, execution first;
The resource that step 305, utilization distribute is carried out this link task.
Flow process as shown in Figure 3, step 302 to step 305 when implementing, main body is the matchmaker and supports platform, identical in main body with step 301, certainly, support the function that platform is finished if exist other main bodys or equipment can finish the matchmaker, also can be carried out by other main bodys or equipment.Step 303 or step 305 are after implementing, and flow process finishes.
Flow process as shown in Figure 3, during enforcement, the duplicate node achievement of link task is to support platform by the matchmaker to carry out the result that this link task in the second download flow process that comprises this link task and requirement result unanimity obtains, the second download flow process herein is used for distinguishing with the first download flow process, be not limited to a fixing download flow process, can be comprise this link task of mentioning in the step 301 and with the first download stream range request result as for any one download flow process.
Flow process as shown in Figure 3, step 301 is when implementing, the matchmaker supports platform determines to exist the link task of carrying out in buffer zone duplicate node achievement, it is multiple to determine that mode can have, the embodiment of the invention provides a kind of preferred implementation, support the matchmaker virtual link task is set in the platform, the pointer of each virtual link task is set to point to the sign of a unique actual link task.Corresponding relation for easy-to-look-up virtual link task and actual link task, support the matchmaker in this example and stored a mapping table that comprises virtual link task identification in the platform, in this mapping table, store the corresponding relation of downloading flow process and virtual link task identification, the corresponding relation that also comprises virtual link task identification and actual link task identification, and the task status of the actual link task of actual link task identification correspondence, instantiation sees also table one:
Table one
In Table 1, exist and be designated 1001, download flow process for two of 1002, be designated 1001 download flow process and comprise 19751 the virtual link task that is designated, be designated 19751 virtual link task correspondence and be designated 8675 actual link task identification, and state that should actual link task is 1, namely complete successfully, in like manner, 1002 comprise and are designated 19786, two virtual link task identifications of 19787, correspondence is designated 8675 respectively, 3786 actual link task identification, wherein, the state that is designated 8675 actual link task is 1, complete successfully, the state that is designated 3786 actual link task is 0, in handling.Also there is other option in Xxxx representative in the table one, and hereinafter the Xxxx implication is with identical herein.
When the matchmaker supports one first download flow process of the current needs execution of platform execution, according to first task of downloading each link task that flow process comprises, in mapping table, obtain the sign corresponding virtual link task identification with this first download flow process successively, further, support platform by the matchmaker and find corresponding actual link task identification according to virtual link task identification, obtain the task status of the actual link task corresponding with actual link task identification, when task status when completing successfully, the matchmaker supports platform and determine to exist this moment the duplicate node achievement of link task in buffer zone.
Certainly, in the specific implementation, except the corresponding relation that stores flow process and virtual link task identification, the corresponding relation that also comprises virtual link task identification and actual link task identification, and outside the task status of actual link task identification, also may store other elements, as, the task status code of flow process, the task grade of flow process, the flow process type code, flow process requires details, the editing objective address of virtual link task correspondence, etc.
In the specific implementation, for the attribute that will download flow process or virtual link task or actual link task expresses clearly, also can enable a plurality of forms and form mapping tables, for example, the specific object of downloading flow process can be as shown in Table 2:
Table two
The specific object of virtual link task and virtual link task and the corresponding relation of downloading flow process and actual link task be as shown in Table 3:
Table three
Also there is other option in Xxxx in the table three, Yyyy representative.
The specific object of actual link task is shown in table four and table five:
Table four
| Skill is examined task |
| Xxxx |
| 3786 |
Table five
| The transcoding task |
| Xxxx |
| 8675 |
In this embodiment, 19751,19786 the virtual link task of being designated is designated 8675 transcoding task by pointed, 19787 the virtual link task of being designated is designated 3786 skill by pointed and examines task, but the task status of examining task owing to the skill that is designated 3786 is 0, in namely handling, therefore, can not multiplexing identification be the duplicate node achievement that 3786 skill is examined task, but request distribute the resource of this link required by task, utilizes the resource of distributing to carry out this link task.
When implementing, the duplicate node achievement of the link task of direct multiplexing execution does not need program downloading content again, reduces the time of downloading, and can save the resource of downloading the required resource of content and occupying in the object content storehouse.Referring to Fig. 4, dotted line among the figure is represented the multiplexing of identical link task between different flow processs, the dotted line circle represent can be multiplexing in the inner different flow instances of same flow process the link task, among Fig. 4, carry out matchmaker's money and download flow process to making, matchmaker's money is to sowing the current-carrying journey fully, matchmaker's money is supported the additional flow process of finished product program to broadcasting urgent download flow process and matchmaker, matchmaker's money comprises the retrieval download to making the download flow process, approval system, tape recovers, fragment is downloaded, the transcoding service, skill is examined service and migration service several links task, matchmaker's money comprises that to sowing the current-carrying journey fully tape recovers, the transcoding service, skill is examined service, the several links task is broadcast in migration service and registration fully, matchmaker's money comprises that to broadcasting the urgent flow process of downloading tape recovers, the transcoding service, skill is examined service, the several links task is broadcasted in migration service and registration, and the matchmaker supports the additional flow process of finished product program and comprises that tape recovers, the transcoding service, skill is examined service, intercepting key frame and the service of additional registration several links.According to the content of Fig. 4 as can be seen, in four flow processs, tape recovery, transcoding service and skill are examined service and can be carried out multiplexing between different flow processs, and support in the different flow instances that broadcast urgent download flow process to sowing current-carrying journey and matchmaker fully to making download flow process, matchmaker's money in matchmaker's money, tape recovery, transcoding service, skill examine service and migration service can be multiplexing, support the finished product program the matchmaker and replenish in the different flow instances of flow process, tape recovers, the transcoding service is that the careful service of skill can be multiplexing.In addition, represented the link task of user's subjective desire as approval system etc., because instability is too high, do not supported multiplexing.
During enforcement, for considering user's wish, the matchmaker supports the conditional policies instruction that platform can also receive user's input, obtain the conditional policies that comprises in the conditional policies instruction, and then download flow process according to the conditional policies that the user selects to first and handle, when first condition of downloading flow process did not satisfy conditional policies, the matchmaker supported platform and stops to carry out the first download flow process, and discharges the resource that it takies.
The conditional policies that comprises in the conditional policies instruction can have multiple, and for example, the time bottom line that flow process finishes perhaps stops to carry out the flow process instruction, etc.Download flow process when implementing, the predetermined time bottom line may be arranged, also may be according to user's subjective value hope by the time bottom line manually is set, also the predetermined time bottom line may be combined with user's subjective value hope the time bottom line is set, several flow processs in the table six for example, the regulation of its time bottom line just has nothing in common with each other, and specifically sees also table six:
Table six
Determined for first time of downloading flow performing above the time bottom line of flow process end when the matchmaker supports platform, this first value of downloading flow process has become 0, and the matchmaker supports platform and stops to carry out the first download flow process, and discharges the resource that it takies, to reduce the waste of resource.
In like manner, receive and stop to carry out flow process when instruction when the matchmaker supports platform, show that this flow process thought that by the user being worth is 0, stop to carry out, and discharge resource that it take, to reduce the waste of resource if first download flow process and still carrying out this moment.
First downloads flow process in implementation process, determines that when the matchmaker supports platform the object content stock is in the content identical with downloading content, when object content storehouse content conflicts namely takes place, should take corresponding strategy to handle, for example, the matchmaker supports platform and can adopt and dodge strategy, stops to carry out first and downloads flow process; The matchmaker supports platform can also adopt overlay strategy, and original identical content in the deletion object content storehouse will be downloaded content registration in the object content storehouse; Perhaps, the matchmaker supports platform can also adopt convergence strategy, merges according to the ratio of setting and downloads original identical content in content and the object content storehouse.In the specific implementation, above-mentioned strategy can preestablish before flow process begins, and also can select to set through the user in the flow performing process, specifically adopted which kind of embodiment to decide as the case may be.
Certainly, when adopting above-mentioned strategy to solve the problem of object content storehouse content conflicts, one very important problem be, how to judge the retention time of the identical content in object content storehouse, for guaranteeing that program can access smooth broadcast, for downloading flow process, need to take full advantage of the identical content in object content storehouse, the solution that provides in this example is:
The matchmaker supports the last retention time and the last retention time of downloading content of the original identical content of platform comparison object content library, the retention time of content identical in the object content storehouse is modified to both maximal values.
Also can be formulated, that is:
The last retention time of the original identical content in the retention time of the content that revised object content storehouse is identical=Max(object content storehouse is downloaded the last retention time of content).
For example, the object library program subject of a talk or essay " first collection of showing sword " by name, keeping final time is on June 10th, 2010, is on June 5th, 2010 if download the last retention time of content, and then the retention time of the identical content in revised object content storehouse is on June 10th, 2010; If downloading the last retention time of content is on June 12nd, 2010, then the retention time of the identical content in revised object content storehouse is on June 12nd, 2010.
Flow process as shown in Figure 3, the duplicate node achievement of multiplexing link task, the precondition that needs to satisfy be: the uniqueness determine mechanism of content.Because no matter be the multiplexing of the multiplexing or whole flow process of link, all be multiplexing for content.That is to say that it is identical requiring to guarantee to exist existing content and will handle the result that wants.So, guarantee that it correctly is multiplexing prerequisite that the content uniqueness is differentiated.
Because it is file-level that the download flow process is moved the content of generation, therefore, a kind of criterion of judging the content uniqueness is to differentiate the homogeny of file fully, the content that the content library of the different plates of TV station is preserved is unit with the program, a program is the set that some files are formed, so, utilize the characteristic of " file in the program " here, concrete differentiation uniqueness mechanism as shown in Table 7:
Table seven
During enforcement, owing to system is constantly safeguarding flow process, for guaranteeing not removed automatically by system logic, the content of a program can repeatedly be locked, and when the content of this program was downloaded end, release once, drop lock subtracts 1, when the drop lock of program is 0, can be removed by system logic.
In the specific implementation, the matchmaker supports the download flow process that platform relates to and comprises following several at least: matchmaker's money is downloaded flow process, matchmaker's money and is downloaded flow process, matchmaker's money and support the finished product program and replenish flow process to sowing current-carrying journey and matchmaker fully to broadcasting to making.Certainly, also may exist other to download flow process, support the interior content download of platform as long as relate to the matchmaker, all belong to the matchmaker and support the download flow process that platform relates to.
The link task processing method that adopts the embodiment of the invention to provide can solve one by one for the problems of the prior art, for example:
1, for the review of a film by the censor of the program of TV station, can revise the program retention time, satisfy the time bottom line that program is prepared before broadcasting, like this, though the review of a film by the censor early finish, when program is prepared before broadcasting, the program that the review of a film by the censor is downloaded is not deleted, does not therefore just need to download again yet, can save resource;
When 2, TV station exists a plurality of channels to play the situation of same program in the short time, the review of a film by the censor of different channel and broadcast before program prepare not need all to carry out programme content and download flow process, duplicate node achievement that can multiplexing completed link task gets final product, avoided repeatedly downloading the repetition and waste that causes resource, can save resource;
3, TV station is when director's editing is movable, need support the program downloading content to making net from the matchmaker, during the major event report, when important news material is write and directed the making net that downloads to repeatedly separately by difference, the duplicate node achievement of multiplexing completed link task can avoid downloading repeatedly the repetition and waste that causes resource equally;
