One embodiment 1 is given below to illustrate concrete application mode of the invention.But those skilled in the art it should be clear that
The invention is not restricted to field where following embodiments.In embodiment 1, task dissemination system of the invention is intellectual property task
Single dissemination system.Job order can be the intellectual property application tasks such as the trademark application by client's submission.
In the present embodiment, the service ability of server is described as follows:Each server is likely to the treatment with varying number
Unit, if the ability of each processing unit is identical, then the disposal ability of server is often different, i.e., assuming that each task (list) institute
It is different in the quantity of unit interval server process task under the premise of the computing capability and storage resource identical that need to process.
Service is assigned three kinds of following forms in the present embodiment:
Form one:Specified services are distributed
Specified services are distributed for the treatment of job order given server.The service needs in advance to receive the configuration of certain server
Process task list feature, after the job order with this feature reaches distributor, the task is directly distributed the clothes by distributor
Business device.
Form two:Previously service distribution
Previously service distribution is used for the job order of same feature by same server process.Distributor presses certain limit
(such as continuous 10,000 job orders) records the characteristic value of distributed job order and the server for the treatment of service is carried out to the task
Number, afterwards, then after the job order for having same characteristic features value is arrived, it is not allocated by ability value, it is directly distributed to the clothes for recording before
Business device.
Form three:Distributed by ability value service
Job order distribution is carried out according to the ability value size of current each server by ability value service distribution, ability value is maximum
Server priority distribution job order, the server-capabilities value for receiving an assignment single accordingly reduce a value.
In this embodiment, for any one task (list), distributor first checks whether to meet assignment of allocation condition, such as
Meet, distribution terminates and task is given the server specified processed;Next checks whether previously service distributive condition,
As met, distribution terminates and is processed the server that task gives previously service;Finally, distributed by ability value service.
For identical specified services that may be present configuration, the past Service Matching and ability value between server, according to
The precedence of the access of storage is carried out.Match somebody with somebody as server of the job order feature with 2 or more than 2 specify
Put, then the job order preferentially distributes each arrangement first server process according to order.Similarly, as a job order feature meets
Server the past condition of 2 or more than 2, then the job order preferentially distributed according to order at the first server of each arrangement
Reason.The specific composition of this task dissemination system is described below.
Distributor is constituted
Dispensing device is mainly made up of calculator and memory.Task distribution method of the invention is in practice with algorithm side
Formula is realized.
1. calculator
Calculated for completing algorithm.
2. memory
If:Server is S, server-capabilities are r, task single eigenvalue is W, then SiRepresent the i-th (1, n) individual server, ri
N () represents the i-th (1, n) disposal ability (number of server processing unit), the W of individual serverjJ-th characteristic value of task.
PW represents the characteristic value of appointed task.
Table 1 below, table 2 and table 3 are set up respectively.
(1) server-capabilities storage
Table 1 presents the ability value of each server.
Table 1:Server-capabilities value table
Server sequence number | Server name | Server-capabilities value |
1 | S1 | r1 |
2 | S2 | r2 |
…… | Si | ri |
n-1 | Sn-1 | rn-1 |
n | Sn | rn |
Service provider's total capacity
(2) specified services storage
Table 2 presents 3 specified services characteristic values of each server.The specified services of actual each server as needed
Characteristic value may be not necessarily limited to the number of quantity.
Table 2:Specified services table
Server sequence number | Server name | Specified services characteristic value 1 | Specified services feature 2 | Specified services feature 3 |
1 | S1 | PW1,1 | PW1,2 | PW1,3 |

n | Sn | PWn,1 | PWn,2 | PWn,3 |
(3) the past service memory
With the development of service, each server service processing multiple tasks lists, so each server can have
One queue of the past service features (or previously servicing single).New list can service single (feature) by the past to server,
Compare, determine whether the job order meets the regular of previously service and carry out service processing by the server, table 3 is illustrated both
Toward the record case of service.According to nearest service time and queue of the frequency to service features (or previously servicing single) can be serviced
Processed, the validity of the past service queue is reduced to improve, improved the efficiency of algorithm.
Table 3:The past agent list (job order client characteristics)
The gain of parameter mode such as ability value is described below.
1. ability value is obtained
If a job order of total r (being the service unit sum of each server) is distributed for distributor, can be by certain rule
(algorithm) r service unit of sequence arrangement from each server matches this r job order, and each service unit distribution one is single.Often
Carry out a list in addition to giving given server or the past server, always give the service unit number of wait most servers.
After one group of r job order distributes to r service unit, then rearrange r job order distribution r service unit, so circulation.This
The ability value of sample server translates into the quantitative value of the service unit that the server has.
2. task single eigenvalue
Task single eigenvalue is primarily referred to as Business Name contained by task odd numbers, time and sequence number, or applicant
Name, identification card number, or the code of unit etc. that task is submitted to.Due to specifically to determine which server job order returns at
Reason, in fact, often submitting the code of unit to as task single eigenvalue from applicant's identification card number or task.
3. specified services characteristic value
As the implication of task single eigenvalue, simply in actual applications, its effect is pin to specified services characteristic value
It is not in face of universal job order to individual tasks list.So, specified services feature services are in the absence of task characteristic value team
Row.
Operation flow is described below.
Configuration parameter
Service unit number according to each server calculates the service ability r of each serveri, configure PWi,j, i=1 ..., n, j
=1,2,3.Agent list and the past agent list are formulated in configuration.
After job order reaches distributor, distributed according to following flow:
1. whether specified services requirement is met.When job order reaches distributor, distributor is by arrangement in specified services table
Sequentially, the specified services characteristic value for meeting certain server by its characteristic value is checked, is met, the job order submitted and is conformed to
The server process asked, and change the service ability value of the server, i.e., its service ability value subtracts 1.Afterwards, job order is extracted special
Value indicative, is stored in the corresponding task single eigenvalue queue of the server, previously services used after being.
2. whether the past service request is met.After job order does not meet specified services requirement, distributor is by previously service
The order of assortment in table, inspection is met the task single eigenvalue of certain server by its characteristic value, is met, and the job order is passed
Hand over satisfactory server process, and change the service ability value of the server, be i.e. its service ability value subtracts 1.
3. distributed by ability value.When job order had not both met specified services requirement, the past service request is not met yet, then divided
Dispensing ability value it is maximum and come most preceding server process, and change the service ability value of the server, i.e. its service energy
Force value subtracts 1.Afterwards, task single eigenvalue is extracted, is stored in the corresponding task single eigenvalue queue of the server, after being previously
Service is used.
Server service list allocation algorithm is given below.
Agent list, the past agent list, configuration server ability value table are formulated in configuration, perform following algorithm, complete job order
Distribution.
If job order is T;There is n server, each server has r respectively1、r2、…、rnIndividual processing unit, and ability value pair
Should be c1、c2、…、cn, total processing unit r=r1+r2+…+rn, then when starting, i-th service ability of server is ri。
Program is as follows:
Notice that ci, cj are likely to occur negative value, but do not influence max (c1, c2 ..., cn) comparing.
The core concept of algorithm is to be provided with one group of n processing unit correspondence job order, each processing unit distribution one above
Job order.Often carry out a list in addition to giving given server or the past server, always give the clothes of most wait tasks treatment
Business device.After one group of n processing unit distributes n job orders, then recalculate one group.The service ability of server, is converted into clothes
The quantity of business unit.When Servers-all is all connected to the job order no less than setting odd number, start next group task.Thus may be used
See, server task distribution method of the present invention can realize distributor by the job order smart allocation of different characteristic to corresponding clothes
Business device, distribution method is not related to probability, and is allocated just for job order and reduces the complexity of algorithm.And the clothes of server
Business ability, correspondence is converted into the quantity of service unit, realizes making clear for service ability.
Additionally, the present invention is compared using ability value, and simple addition and subtraction modification ability value, instead of the probability of other algorithms
Differentiate and probability amending method, clear thinking, calculate simple.
The basic principles, principal features and advantages of the present invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way for above-described embodiment, it is all to be obtained by the way of equivalent or equivalent transformation
Technical scheme, all falls within protection scope of the present invention.
