Next, the method that a kind of adjustment task priority that the embodiment of the present invention is provided is discussed in detail.Fig. 1 is this hair
A kind of flow chart of the method for adjustment task priority that bright embodiment provides, this method include：
S101：Obtain log information.
Document distribution system can preserve the log information of generation to database after completing corresponding file download task
In.
Include service IP address and corresponding fileinfo in every log information.With accumulative, the data of time
A large amount of log information is stored in library, correspondingly, in the log information of acquisition may include have multiple service IP address with
And fileinfo corresponding with each service IP address.
According to the service IP address, corresponding server can be searched, to obtain the real-time network conditions of server.Text
Relevant information when file download is contained in part information, these information can reflect network feelings corresponding when download file
Condition.In embodiments of the present invention, Main Basiss service IP address and fileinfo in log information, carries out task priority
Update.
In view of the log information data volume stored in database is larger, within current time immediate a period of time
The network condition of server when log information can more reflect download file, so, it in embodiments of the present invention, can be according to pre-
The cycle time first set obtains the log information stored in the cycle time from the database.Correspondingly, can be
Task priority is once updated in a cycle time.
Wherein, the length of cycle time can be set according to actual demand, be not specifically limited herein.
S102：According to each service IP address, the running state parameter of corresponding server is obtained.
One service IP address corresponds to a server, and document distribution system is according to service IP address information, testing service
The running state parameter of device.The running state parameter reflects the real time execution situation of server.
Latency response time or packet loss of server etc. can accurately reflect the current network feelings of server
Condition in embodiments of the present invention can be using Latency response time or packet loss as the running state parameter of server.
In the concrete realization, the real-time network feelings of the server corresponding to ping orders test service IP address can be used
Condition.
By taking Latency response time as an example, the ping for the Latency response time that service IP address is 192.168.10.10 is obtained
Order is as follows：
64bytes from 192.168.10.10:Icmp_seq=0ttl=254time=1.557ms
64bytes from 192.168.10.10:Icmp_seq=1ttl=254time=1.601ms
64bytes from 192.168.10.10:Icmp_seq=2ttl=254time=1.814ms
64bytes from 192.168.10.10:Icmp_seq=3ttl=254time=1.537ms
64bytes from 192.168.10.10:Icmp_seq=4ttl=254time=1.577ms
Wherein, time indicates Latency response time.Latency response time is shorter, then it is better to represent network condition.
In the example above, multiple Latency response time is obtained, passes through the side being averaged to these Latency response times
Formula calculates server finally corresponding Latency response time.
The mode of multiple exploitation average value, can promote the accuracy of Latency response time.
S103：According to fileinfo corresponding with the service IP address, the historic state of the server is determined
Parameter.
The relevant information of file download is contained in fileinfo, for example, filename, file size, file start to download
Time, end of file download time and file status information etc..
Filename is for distinguishing different files；File status information can reflect file download as a result, specific real
In existing, digital representation file status information can be used, when file status information is " 0 ", indicates file download success；Work as file
When status information is " 1 ", file download failure is indicated.
Historic state parameter can reflect network condition of the server within the past period.File download rate and
File download success rate is directly related with the network condition of server, and file download rate is faster, file download success rate is higher,
Illustrate that the network condition of server is better.In embodiments of the present invention, file download rate and file download success may be used
The two parameters of rate are as historic state parameter.Specifically, can be according to file size that the fileinfo includes, file
Start download time and end of file download time, calculates the file download rate of the server；And according to the file
The file status information that information includes calculates the file download success rate of the server.
Each service IP address has its corresponding fileinfo, in the multiple service IP address for including in log information
Occurs multiple situation there may be the same service IP address.For example, include 10 log informations in log information, every
All include in log information there are one service IP address, these service IP address be followed successively by 192.168.10.10,
192.168.10.11、192.168.10.12、192.168.10.10、192.168.10.10、192.168.10.13、
192.168.10.14,192.168.10.135,192.168.10.10 and 192.168.10.16, wherein service IP address
192.168.10.10 occurring 4 times.
In log information, service IP address often occurs once, there is its corresponding fileinfo.But it comes from same
The file download request of a service IP address, because on same server, network condition is the same.So
, can be using service IP address as processing unit when calculation document downloading rate and file download success rate, it will be in log information
The corresponding fileinfo of same service IP address is summarized, to calculate the corresponding file download of each service IP address
Rate and file download success rate.
By taking file download rate as an example, opened comprising the file size corresponding to a file, file in a fileinfo
The information such as download time and end of file download time that begin can first calculate under each file in embodiments of the present invention
Rate is carried, then the downloading rate of the corresponding All Files of the same service IP address is averaged again, which is made
For the corresponding file download rate of the service IP address.
It in the concrete realization, can be according to formula：File download rate=file size/(end of file download time-text
Part starts download time), calculate the file download rate of each file.
By taking file download success rate as an example, the corresponding fileinfo of the same service IP address is summarized, Mei Gewen
Include file status information in part information, can know the download of some file according to file status information as a result, being to download
Success or failed download, so as to count the corresponding file download success rate of the service IP address.
S104：According to preset rules, to the corresponding running state parameter of all service IP address and described go through
History state parameter is handled, and determines the corresponding precedence information of each service IP address, and the priority is believed
In breath update to database.
Each service IP address has its corresponding running state parameter and historic state parameter.
It in embodiments of the present invention, can be according to the weighted value of preset parameters, to all business IP
The corresponding running state parameter in address and historic state parameter progress are integrated ordered, determine each business IP
The corresponding precedence information in address.
In view of running state parameter reflects the current network conditions of service IP address, historic state parameter reflects industry
The web-based history situation for IP address of being engaged in, so, in the setting of weighted value, the weighted value of running state parameter can be arranged
It is higher than running state parameter.
Using Latency response time as running state parameter, file download rate and file download success rate are as history shape
For state parameter, the weighted value more than file download rate that the weighted value of Latency response time can be arranged, file download
The weighted value more than file download success rate of the weighted value setting of rate.It, can be according to accordingly when carrying out integrated ordered
The sequence of Latency response time from small to large, is ranked up each service IP address；When there is multiple service IP address corresponding
When Latency response time is identical, then the sequence according to the file download rate of these service IP address from high to low, to these industry
Business IP address is ranked up；When there is the corresponding file download rate of multiple service IP address identical, then according to these business IP
The sequence of the file download success rate of address from high to low, is ranked up these service IP address.In addition, when there are multiple industry
When the case where Latency response time of IP address, file download rate and file download success rate all same of being engaged in, it can set at random
The priority orders of these fixed service IP address, can also be according to the preferential of these service IP address originally stored in database
Grade sequence is set, and is not specifically limited to this.
In the manner described above, after the sequence of finishing service IP address, can according to priority orders from high to low, according to
The priority of the secondary each service IP address of setting.
It is to be ranked up to service IP address according to the weighted value of each parameter, naturally it is also possible to use it in above-mentioned introduction
He carries out comprehensive analysis calculating by algorithm, is not specifically limited to this.
After determining the corresponding precedence information of each service IP address, the precedence information can be updated to number
According in library, to realize that the dynamic of precedence information in database updates.
Correspondingly, document distribution system is when receiving the file download request that each operation system is sent, it can foundation
The service IP address carried in each file download request obtains each file download request and corresponds to from the database
Priority；Since the precedence information stored in database can dynamically be updated according to actual network environment, so
The priority of file download request more rationally can ensure the stability of file download rate.
The precedence information of each service IP address can be stored in table form in the database, as shown in table 1,
| Serial number | Service IP address | Priority |
| 001 | 192.168.10.10 | 100 |
| 002 | 192.168.12.18 | 200 |
| …… | …… | …… |
Table 1
For example, from the file download request that IP address is 192.168.10.10, task scheduling modules are from database module
It is 100 to inquire the corresponding task priority information of the IP address, then the download priority for its distribution is 100.
One service IP address corresponds to a server, on a server may there are one or multiple operation systems, often
A operation system can send file download request according to business demand to document distribution system, same for the ease of distinguishing
Different operation systems under service IP address, can be arranged corresponding System Number, namely in file download request in addition to
It carries except service IP address and filename, it can be with carrying system number and request transmission time.
Wherein, the purpose that request transmission time is carried in file download request is to distinguish from the same service IP address
Multiple file download requests priority.
When the same service IP address is corresponding with multiple file download requests, since what is stored in database is each business
Therefore the corresponding priority of IP address can be these file download requests point according to the precedence information stored in database
With identical priority, at this point, can be according to the sequencing of the request transmission time of each file download request, further
Determine the priority of these file download requests.
For example, there are 2 to be asked from the download that IP address is 192.168.10.10, the request transmission time of A is asked to be
20180101000001, it is 20180101010101 to ask the request transmission time of B, then the download priority after distributing is respectively
100、101。
It should be noted that log information is stored in database, in addition to being used to calculate running state parameter and going through
Outside history state parameter, the specifying information for recording each file download request is can be also used for, for use in looking into whenever necessary in the future
It sees details, can also include file download correspondingly, in log information other than including service IP address and fileinfo
