Description
Technical Field
The invention relates to a design method and implementation used in computer file transmission software, and provides a method and implementation for presetting transmission priority in an automatic file transmission process, which has the function of enabling a user to efficiently, automatically, individually, flexibly and timely set the priority of a file transmission task.
Background
At present, many computer software programs provide a file transfer function, and because a scenario of simultaneous transfer of multiple files occurs (for example, if multiple senders send files simultaneously when a user receives files), under the condition of limited bandwidth, the user needs to preferentially transfer one part of files and delay to transfer another part of files, so that part of software programs provide a transfer priority setting function on the basis of the file transfer function.
1. Description of existing file transfer software:
existing file transfer software is a type of software having a file transfer function, and has a function of transferring a file from one role to another role. Comprises the following components:
role: a sender and a receiver;
role identification: user name, IP address port, etc.;
basic file transfer function: sending/uploading/receiving/downloading the file;
and (3) transmission queue: the maximum value of the number of file tasks transmitted simultaneously is limited.
Typical file transfer software includes transfer software based on an FTP protocol, an uploading and downloading tool based on a P2P protocol, and the like, and in addition, the functions of sharing after uploading and downloading and the function of super-large attachments of various mailbox products, which are possessed by various network disk products at present, belong to the functions of file transfer software essentially.
2. The transmission priority of the existing file transmission software sets the function description:
the existing file transmission software modifies the common mode set by the file transmission priority: the software sets some common priority values, such as "low", "medium", "high", the priority degree "low" < "medium" < "high", the default file transfer tasks all adopt the same value, such as "medium", the file transfer speed of the higher priority file task is higher than that of the low priority file task, the queue insertion priority transfer is higher, and the like. The file set being transmitted is called transmission queue, the maximum number of simultaneous concurrent tasks is set in software and represents the maximum capacity of the transmission queue, when the number of file tasks needing to be transmitted exceeds the maximum capacity, the excess files are in queue waiting state, the task set in queue waiting state is called waiting queue, each file task in the transmission queue and the waiting queue is generally arranged according to priority and the time point sequence of the file needing to be transmitted, the files with high priority are arranged in front, and the files with earlier time points are arranged in front when the priority is the same.
Abstract meaning of task queue position in wait queue: queuing the waiting tasks according to a certain sequence (the tasks with high priority are arranged in the priority sequence, and the tasks with high priority are in front), and when the transmission queue is not full, sequentially moving the file tasks in the waiting queue into the transmission queue according to the queuing sequence;
abstract meaning of task arrangement position in transmission queue: the files being transmitted are positioned at different positions in the queue according to different priorities, the tasks with the same priority are ahead of the tasks with the high priority, and the sequence is determined by other factors, such as the time point when the files need to be transmitted. Different positions in the queue may have different transmission rates (or all files may have the same transmission rate), and the software may allocate the transmission rate of each file in the transmission queue according to a certain algorithm according to the priority weight. When a file task in the waiting queue needs to enter the transmission queue due to priority elevation under the condition that the transmission queue is full, the task arranged at the tail part of the queue is firstly moved into the waiting queue.
When the transmission of a file task in transmission is completed, the file task is moved out of the transmission queue, and the file in the front of the waiting queue is moved into the transmission queue. When a user considers that a certain file needs to be transmitted preferentially, the files in the transmission queue and the waiting queue can be selected through the software graphical interface, the priority of the selected file is set, the priority is adjusted to be high or low, the task can move to a new arrangement position according to the modified priority, for example, after the priority of a file transmission task A in the waiting queue is adjusted to be high, if a file transmission task with the priority lower than the priority of A exists in the transmission queue, the transmission queue can move a task with the lowest priority to the waiting queue, and the A can move to a proper position of the transmission queue for transmission. If the priority of the file transmission tasks in the transmission queue is higher than that of A, A moves to the arrangement position corresponding to the waiting queue according to the new priority to continue waiting.
3. The problems to be solved by the invention are as follows:
the priority setting function of various types of file transfer software at present generally requires a software user to manually set an ongoing file transfer task (generally acting on the ongoing file transfer task), and requires setting after the file is ready to start to be transferred. When the document to be transmitted has more tasks, the user is complicated to operate, and the user's intention cannot be responded to in time because the document can be operated only after the document is ready to be transmitted.
In some cases, users have high requirements on the file transfer efficiency and the transfer automation degree, such as a special line environment file transfer application scenario between financial institutions. Therefore, a new file transmission priority setting mode needs to be designed, so that unnecessary manual operation is saved, and the transmission efficiency and the transmission automation degree are improved.
In the prior art, the main problems of the transmission priority setting function of file transmission software are as follows:
i. the operation is inefficient: the transmission priority setting function of the existing file transmission software needs to manually operate a program graphical interface and select a file task needing to modify the transmission priority, has low operation efficiency and cannot adapt to an application scene of transmitting a large number of files;
response hysteresis: the transmission priority setting function of the existing file transmission software needs to modify the file transmission task after the file transmission task appears, so that the problem of hysteresis exists, and the intention of modifying the transmission priority by a user cannot be responded in time.
insufficient synergy: the transmission priority setting function of the existing file transmission software is that a sender can only determine the priority of a sending direction, a receiver can only determine the priority of a receiving direction, and the sender and the receiver can not cooperate through a software mechanism to jointly set the priority of the whole file transmission process.
Not flexible enough: the transmission priority setting of the existing file transmission software does not use other reference dimension variables, only can manually adjust the priority according to the intention of a user, but cannot automatically match the conditions and then adjust the priority when the files are transmitted by setting personalized dimension variable conditions.
In order to solve the technical problems, a new technical scheme is especially provided.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to the attached drawings of the specification, the invention provides a technical scheme that: a method for pre-prioritizing file transfer tasks, the method comprising the steps of:
step one, a user informs a priority rule of a file transmission system through a well-agreed notification mechanism;
step two, when a batch of files are ready to be transmitted, matching is carried out according to priority rules to obtain the priority of each file;
and step three, inserting the files into a waiting queue in sequence according to the matching result, and sequencing according to the time points of file addition and ready transmission when the priorities matched according to the priority rule are the same. The whole process is based on the preset priority rule, software senses in advance, and automatically matches with the personalized priority configuration rule, so that the transmission priority is automatically realized without any manual operation. Meanwhile, the invention provides multidimensional preset conditions, so that a user can customize the conditions individually according to the requirements and can adapt to various use scenes.
Preferably, the notification mechanism in the first step is that, from the perspective of the sender, the user can make the file transfer client perceive in advance which files have high priority to be sent and which files have low priority to be sent by setting a convention.
Preferably, from the perspective of the recipient, the user can make the file transfer client decide which files have high priority to be received and which files have low priority to be received by setting up a convention, without manually clicking to increase the priority or decrease the priority of a certain file.
Preferably, after the priority has been pre-set, the tasks in the waiting queue can still be increased in priority again.
Preferably, the priority rule in step one is to allow the user to preset the corresponding transmission priority value according to different file characteristics before the file transmission is started through the file transmission software.
Preferably, when each file transfer is started, the transfer priority of the file can be automatically set according to the characteristic condition of the file.
The definition of the transmission priority setting function of the existing file transmission software of the invention is as follows: the software program function and man-machine interaction mode with the function of adjusting the file transmission priority of the file being transmitted in a manual adjustment mode comprise a sender (uploading party) file transmission client, a receiver (downloading party) file transmission client and a receiving (downloading) party, wherein the sender (uploading) priority is adjusted (determined which files are preferentially sent) in a manual mode, and a plurality of software products are available in the current market.
The whole scheme content of the invention is to add three functional designs on the basis of the transmission priority setting function of the existing file transmission software:
1. an idea of transmission priority presetting: file transmission software, which can allow a user to preset corresponding transmission priority values according to different file characteristics before file transmission starts; when each file transmission is started, the transmission priority of the file can be automatically set according to the characteristic condition of the file.
2. The invention provides a priority setting value matching algorithm. The transmission priority of all files can be matched according to a preset configuration, and the configuration is called a priority rule.
One priority rule contains the following elements:
| rule name |
| Priority condition |
| Priority level |
Wherein "priority condition" indicates that the file task satisfying the condition will use the priority of the rule when transmitting. The priority condition may set the following elements:
1) file name wildcards (regular expressions) that adjust the transmission priority of files with keywords or additional fields in the file name. For example, files with txt suffix, pk tag, or "market" keyword have higher priority for transmission or reception;
2) the file size can be set as a size interval, and the transmission priority meeting the file size is adjusted. If the small files smaller than 1M are sent or received preferentially, the situation that a large number of small files need to be transmitted due to long time for transmitting a certain large file by a transmission thread is avoided;
3) and the time period can set an open time period and a forbidden time period, and the transmission priority in the time period is adjusted. Such as adding incoming tasks to send or receive first between 8:30 AM and 11:00 AM, etc.
4) The task type can adjust the priority of sending or receiving tasks.
5) The common address identification conditions of the opposite side include an IP address port, a user account name and the like. In the file transfer job, there is a concept of "the other party" with respect to the user's own side of the file transfer software, and "the other party" means the receiving party for the transmission job, and "the other party" means the transmitting party for the reception job. The element can enable file transmission software to set different transmission priorities according to different addresses of opposite parties. For example, to send a plurality of files to different receivers at the same time, the effect of "the files sent to one part of the receivers have high sending priority, the files sent to the other part of the receivers have low sending priority" can be achieved by setting the "condition for identifying the address of the other party".
6) The other side identification condition, this element is similar to "other side address identification condition", in the general file transmission system, the role identification has user concept, generally sets the user identification, for example: the security dealer, the bank, the fund company, the VIP client, the common client and the like can use different network segments to which the IP addresses belong as identity marks if the role marks are carried out through the IP address ports. The element can enable the file transmission software to set different transmission priorities according to different identification marks of the opposite side. For example, to send multiple documents to different recipients simultaneously, the documents sent to the dealer user have a high priority, the documents sent to the fund company user have a low priority.
7) The task adds information identification, and a sender of file transmission can add some self-defined information and send the self-defined information to a receiver along with the file. This element can be made possible by the file transfer software by setting different sending and receiving priorities based on the different information identifiers attached by the sender. For example, the sender may attach a "emergency" word to a file that the receiver needs to receive as soon as possible, and the sender may set to preferentially send the file with the "emergency" information, and the receiver may also set to preferentially receive the file with the "emergency" information. The element supports the sender and the receiver to jointly set the priority of the whole file transmission process through convention, and the flexibility is high. (similar to the function of the filename wildcard)
8) Sender priority setting information, this element allowing the receiver to set different reception priorities according to the sending priority set by the sender. For example, for a file with a high transmission priority from the sender, the receiver also receives with a high priority.
9) This element allows the receiver to set different reception priorities according to the "reception priority proposal value" set by the sender with respect to the proposal value of the reception priority by the sender. For example, for a file for which the sender suggests a high reception priority, the receiver receives with a high priority.
3. An automatic mechanism is provided, from the perspective of a sender, a user can enable a file transmission client to sense in advance which files have high priority to be sent and which files have low priority to be sent by setting a convention, and meanwhile, from the perspective of a receiver, the user can enable the file transmission client to determine which files have high priority to be received and which files have low priority to be received by setting the convention, and the user does not need to manually click to improve the priority of a certain file or reduce the priority of the certain file. After the priority is preset, the tasks in the waiting queue can still increase the priority again, and the use is very flexible.
The invention can set priority conditions from multiple dimensions, meets various use scenes of users, can be used for any file transmission scene only by setting the priority rule needing to be matched by the user, and has good universality. Solves the problems listed in the section "technical problems to be solved by this patent application" [ iv. not flexible enough ].
The invention expands the function based on the function of the existing file transmission software, and realizes the process of automatic personalized priority transmission as follows: the user informs the file transmission client end of the transmission priority of the files meeting certain rules through a preset personalized priority mechanism. The software calculates the transmission priority of each file according to the matching algorithm before transmitting the files, and then transmits the files according to the priority, and the whole scheme is as shown in figure 1. The method comprises the following steps:
the first step is as follows: the personalized priority rule can be configured by a file transmission system client, and comprises 3 aspects of contents:
1) a personalized priority rule name;
2) priority conditions (filename, time period, file size, send/receive)
3) Priority value
The second step is that: and adding a batch of files to be sent, and automatically matching and adjusting the sending or receiving priority of each file by the system according to a preset personalized priority rule. The detailed implementation of the algorithm for matching priority rules is as follows:
there are two ways:
firstly, a weighted priority matching algorithm scheme, as shown in fig. 2:
1) configuring a priority rule and distributing weights to all conditions in the rule;
2) if some of the conditions need to be subdivided, as in fig. 3, the finer grained conditions subdivided by the condition are assigned weights, and the sum of the weights is equal to the weight of the condition. (if the filename wildcard weight is 0.5, if we want to set pdf prior to txt, we can assign pdf with 0.3 and txt with 0.2);
3) accumulating all the weights to obtain a value which is a priority value;
4) and arranging the transmission priority according to the calculated priority value.
Secondly, matching all the conditional algorithm schemes, as shown in the attached figure 4:
1) for each file task, traversing preset priority rules in sequence;
2) when the task type of the file task is inconsistent with the preset task type, continuously traversing the next priority rule; if the rule is consistent, matching the file name regular expression of the rule;
3) when the file name of the file does not match the file name regular expression of the rule, continuously traversing the next priority rule; when the rule is consistent, the size range characteristics of the rule are matched;
4) when the file size does not accord with the size range set by the rule, continuously traversing the next priority rule; matching the time range of the rule when the rule is consistent;
5) when the file transmission time does not accord with the time range set by the rule, continuously traversing the next priority rule; if they match, the priority set by the rule is used.
In the second scheme, a plurality of priority rules can be configured through the file transmission system, and the matching sequence is matched from low to high in priority according to the configured sequence number of the personalized priority rules. When the task is completely matched with an individualized priority rule, the priority set by the rule is used, and the rule after traversal is not performed; and when the task does not meet any personalized priority rule, the transmission is directly carried out according to the priority of the task.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
