Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
The process flow diagram of the document transmission method that provides for preferred embodiment according to the present invention shown in Figure 1.As shown in Figure 1, the document transmission method that preferred embodiment of the present invention provides comprises step 101～103.
In step 101, transmitting terminal reads file waiting for transmission, and said file is split as a plurality of blocks of files.For example, transmitting terminal reads file A waiting for transmission, and file A waiting for transmission is split as five blocks of files (that is, blocks of files a1, a2, a3, a4, a5).Wherein, can file A be split as five blocks of files of the same size, perhaps as required file A be split as five blocks of files that cause not of uniform size.Yet the present invention does not limit this.
In step 102, said transmitting terminal transmits said blocks of files according to the preset strategy invokes thread through function NetGroup.addHaveObject.For example, the transmitting terminal invokes thread is through function NetGroup.addHaveObject (a1, a5) transfer files piece a1～a5.
In present embodiment; Preset strategy is: said transmitting terminal is set the priority of all threads in the thread pool; And the corresponding relation of definite blocks of files and thread priority; Said transmitting terminal calculates the idleness of all threads in each priority, and calls corresponding thread according to the idleness of thread in the size of blocks of files and the corresponding priority of said blocks of files and transmit said blocks of files.Particularly, when corresponding to not of uniform size the causing of the blocks of files of same thread priority, transmitting terminal calls the higher bigger blocks of files of thread transmission of idleness in the said priority, calls the less blocks of files of thread transmission that idleness is lower in the said priority.When corresponding to the size of the blocks of files of same thread priority when consistent, the thread in the said priority of transmitting terminal random call transmits said blocks of files.In this, the idleness of thread referred to sample in the period, and the free time of thread accounts for the number percent of sampling period.The idleness of thread calculates and can be real-time calculating or regularly calculating.Yet the present invention does not limit this.
For example, the corresponding relation of thread and its priority is as shown in the table in the thread pool of transmitting terminal setting.
| The thread name | Priority |
| Thread 1 | The first estate |
| Thread 2 | The first estate |
| Thread 3 | The first estate |
| Thread 4 | The first estate |
| Thread 5 | Second grade |
| Thread 6 | Second grade |
| Thread 7 | Second grade |
| Thread 8 | The tertiary gradient |
| Thread 9 | The tertiary gradient |
| Thread 10 | The tertiary gradient |
As above shown in the table, each thread priority is followed successively by from high to low: the first estate, second grade, the tertiary gradient.Wherein, the present invention is not limited to thread and the priority corresponding relation in the table.In practical application, can reset thread and priority as required.
In addition, transmitting terminal is also confirmed the corresponding relation of blocks of files and thread priority.For example, during as if transmitting terminal transfer files A, B and C, transmitting terminal is split as blocks of files a1～a5 with file A, and file B is split as blocks of files b1～b4, and file C is split as blocks of files c1～c3.Wherein, The not of uniform size of blocks of files a1～a5 (for example causes; Blocks of files is followed successively by by big extremely little order: blocks of files a1, blocks of files a2, blocks of files a3, blocks of files a4, blocks of files a5), the size of blocks of files b1～b4 is consistent, and the size of blocks of files c1～c3 is consistent.Simultaneously, transmitting terminal for example can confirm that the corresponding relation of blocks of files a1～a5, b1～b4 and c1～c3 and thread priority is as shown in the table.
| Blocks of files | Thread priority |
| Blocks of files a1～a5 | The first estate |
| Blocks of files b1～b4 | Second grade |
| Blocks of files c1～c3 | The tertiary gradient |
In present embodiment; Because the not of uniform size of blocks of files a1～a5 causes; Therefore; Transmitting terminal calls the higher bigger blocks of files of thread transmission of idleness in the corresponding thread priority (that is, the first estate) of blocks of files a1～a5, calls the less blocks of files of thread transmission that idleness is lower in the said priority.For example; If the idleness of the thread in the first estate priority from height to low order is: thread 1, thread 2, thread 3, thread 4; The idleness of the thread of second level priority from height to low order is: thread 5, thread 6, thread 7, the idleness of the thread of tertiary gradient priority from height to low order is: thread 8, thread 9, thread 10.Correspondingly, transmitting terminal calls the thread 1 transfer files piece a1 in the first estate, invokes thread 2 transfer files piece a2, invokes thread a3 transfer files piece a3, invokes thread 4 transfer files piece a4.Simultaneously, transmitting terminal calls the thread 5 transfer files piece a5 that idleness is the highest in second level priority.In addition, transmitting terminal random call thread 6 transfer files piece b1 in the remaining thread from second grade, invokes thread 7 transfer files piece b2 call higher thread 8 of idleness in the tertiary gradient priority and thread 9 transfer files piece b3 and blocks of files b4 respectively simultaneously.In addition, transmitting terminal can call the thread 10 transfer files piece c1 in the tertiary gradient priority.Can wait for the thread processing again after the free time in the corresponding priority for blocks of files c2 and c3.
In another embodiment; Preset strategy is: said transmitting terminal is set the priority of file to be transmitted; And thread is included into different classes of according to the idleness of all threads in the thread pool; And confirm priority and other corresponding relation of thread class of file to be transmitted, and the size of the blocks of files that splits according to file to be transmitted is called in each classification the blocks of files that thread accordingly transmits the file of corresponding priority.Particularly; When corresponding to not of uniform size the causing of same other blocks of files of thread class; Transmitting terminal calls the higher bigger blocks of files of thread transmission of the not busy rate of said thread classification hollow, calls the lower less blocks of files of thread transmission of the not busy rate of said thread classification hollow.When corresponding to the size of same other blocks of files of thread class when consistent, the thread in the said thread classification of transmitting terminal random call transmits said blocks of files.In this, the idleness of thread referred to sample in the period, and the free time of thread accounts for the number percent of sampling period.The idleness of thread calculates and can be real-time calculating or regularly calculating.Yet the present invention does not limit this.
Particularly, the priority of the file to be transmitted of transmitting terminal setting for example is followed successively by from high to low: the first order, the second level, the third level.Yet the present invention does not limit this.In other embodiment, the priority of file to be transmitted can be set as required.In addition, the thread in the thread pool is that the criteria for classifying is divided with the idleness.For example; Thread can be divided into three classifications according to idleness, and particularly, idleness can be classified as first category more than or equal to 75% thread; Idleness is greater than 50% and can be classified as second classification less than 75% thread, and idleness is less than or equal to 50% thread can be classified as the 3rd classification.Wherein, the present invention does not limit the criteria for classifying of thread.In addition, transmitting terminal is also confirmed priority and other corresponding relation of thread class of file to be transmitted.For example, the file to be transmitted of the first order is corresponding to the thread of first category, and partial file to be transmitted is corresponding to the thread of second classification, and the file to be transmitted of the third level is corresponding to the thread of the 3rd classification.In this, the priority of file to be transmitted and thread classification are man-to-man relation, yet the present invention is not limited thereto.In other embodiment, file to be transmitted can be set as required and thread classification corresponding relation is the relation of one-to-many or multi-to-multi.Wherein, other corresponding relation of file to be transmitted and thread class is for example shown in the following table.
| File to be transmitted | File Privilege to be transmitted | The thread classification |
| File D, E | The first order | First category |
| File M, N | The second level | Second classification |
| File P, Q | The third level | The 3rd classification |
In present embodiment, the idleness that transmitting terminal calculates all threads can be included into corresponding classification with thread.In this, the corresponding relation of thread and its classification is for example shown in the following table.
With transmitting terminal transfer files D, M is example; Transmitting terminal for example is split as three blocks of files d1～d3 with file D; And the not of uniform size of blocks of files d1～d3 (for example causes; Blocks of files is followed successively by by big extremely little order: blocks of files d1, blocks of files d2, blocks of files d3), transmitting terminal is split as three blocks of files m1～m3 of the same size with file M.Therefore, transmitting terminal can call the highest thread a transfer files piece d1 of idleness in the corresponding thread classification (that is, first category) of file D, invokes thread b transfer files piece d2, invokes thread c transfer files piece d3.Simultaneously; Transmitting terminal can call the corresponding thread classification of file M (promptly; Second classification) the thread d transfer files piece m1 in, thread e transfer files piece m2 (perhaps, invokes thread d transfer files m2; Invokes thread e transfer files piece m1), call the higher thread f transfer files piece m3 of idleness in the 3rd classification simultaneously.
In step 103, receiving end call function NetGroup.addWantObject receives said blocks of files from said transmitting terminal.
In present embodiment; Transmitting terminal is before receiving end transfer files piece; Transmitting terminal sends first instruction and gives receiving end; Receiving end receives the first instruction back response NetGroup.Replication.Fetch.Result incident, and call function NetGroup.addWantObject receives blocks of files from transmitting terminal.And after receiving end received blocks of files from transmitting terminal, receiving end sent second instruction and gives transmitting terminal.Wherein, after first instruction that the receiving end receiving end/sending end sends, carry out blocks of files and receive preparation, transmitting terminal can confirm that receiving end has received blocks of files after receiving second instruction of receiving end transmission.In addition, transmitting terminal can at first send file header, and receiving end calls NetGroup.addWantObjects (0,0) and receives file header, and wherein, file header is preserved the essential information (for example, filename and file size etc.) of file.In this, the reception of blocks of files order is not limit, as long as guarantee at first to receive file header.In addition, receiving end receives and preserves the blocks of files that receives after the blocks of files, all finishes receiving until the All Files piece of file, preserves file at last.
In present embodiment, when being client as if transmitting terminal, receiving end can be client or server.When receiving end was client, transmitting terminal can be client or server.The present invention does not limit this.
