It is fully disclosed to those skilled in the art.
In the prior art, when carrying out load distribution, the difference of the same session of certain load may be requested assignment to not
Same server, thus leads to conversation.In description herein, load can be client.For example, in certain client
On, user has input the username and password of login, is done shopping with logging in related web site.Login corresponding to the register
Request may be allocated to server A.Thus server A saves the session by the logging request.When user is following
When the related web site is done shopping, the corresponding request of shopping operation may be allocated to server B, and server B
There is no any information of the session.For server A, although saving the session, probably because predetermined at one
Any request is not received from client in the time limit of justice, leads to conversation.
In order to remain session when carrying out load distribution, according to an aspect of the present invention, a kind of load point is provided
Method of completing the square.Fig. 1 shows the schematic flow chart of load allocation method 100 according to an embodiment of the invention.Such as Fig. 1 institute
Show, load allocation method 100 includes step S110, step S130 and step S150.
In step s 110, the session request from client is received.
Session (session) is the sequence of the unbroken request and response between client and server.Client to
Server sends request.After server receives request, the response to request is sent to client.
The request for the first time that user end to server is sent is the request for needing to create session.This request to be asked to multiple for the first time
Ask the beginning counted in logic.It is requested for the first time according to this, server can obtain the special identifier symbol of client.That is,
Server starts to remember the request of the client He the client.For example, when user logs in or adds into shopping cart one
When commodity, a session is begun to.Server can identify client according to session, for example session level variable note can be used
The user name password that has inputted of record active user thus sends every time without user and requests all to re-enter, can be with
For recording some other information related with currently this time session.When client clearly terminates session or server one
Not from when client any request of reception in a predefined time limit, session just finishes.After conversation end, server is just forgotten
The client and the request of the client are remembered.
Specifically, user opens a browser, accesses some webpage (web) website, clicks in this web site more
A hyperlink accesses the multiple web resources of server, is then shut off browser, whole process can be referred to as a session.Once
Browser is closed, when reopening browser, cannot need to create a meeting again using last session
Words.In short, session is the primary call between client and server, such as to be realized in the way of browser.
As described above, a session may include multiple requests.In this step, it can receive belonging to from client
One request of special session.The received request of institute can be requests for the first time, may not be and requests for the first time.
In step s 130, according to session request, the unique identifier of client is obtained.
Each session request includes the information of the unique identifier about client.Server can be according to session as a result,
To determine client.According to the received session request of institute, the unique identifier of the available client of server.The specific identifier
Which client symbol identifies the session request from.
Optionally, unique identifier is address Internet protocol (IP) of client, such as 221.217.241.***.It is logical
It often, include the IP address of client in session request.The IP address of each client be it is relatively-stationary, can be used for identifying
Client.Be using IP address as the unique identifier of client it is very convenient and practical, can accurately identify visitor
Family end, to guarantee the smooth realization of scheme.
It is appreciated that unique identifier is also possible to the other identifier information of client, as long as the mark in addition to IP address
Information can uniquely identify client.
In some instances, client may access destination server by proxy server.Destination server is visitor
It is expected the server of session therewith in family end.In these examples, the session request of client can be transmitted to by proxy server
Destination server, thus destination server obtains the unique identifier of client via proxy server.
In step S150, client is distributed to the special services in all available servers based on unique identifier
Device.
The particular server is the server for the client service.The particular server can be the spy according to client
Determine determined by identifier.One client of each unique identifier unique identification, thus, it is possible to determine each client point
The specific server of dispensing.
In above-mentioned load allocation method 100 of the invention, using the unique identifier of client establish client with it is specific
Mapping relations one by one between server, so as to protect during multiple client is distributed to different operation unit
Card by particular clients, belong to same session request assignment to same server, thus keep session.
Optionally, unique identifier being based in the step S150 of above-mentioned load allocation method 100, client is distributed into institute
Have in the particular server in available server, unique identifier can be the IP address of client.It, can be in step S150
Client is distributed into particular server based on any information in IP address.For example, can according to IP address last
Position client is distributed into particular server.It can be that the client of even number distributes to server A by last of IP address,
It is that the client of odd number distributes to server B by last of IP address.
Optionally, in step S150, client is distributed to particular server by first three IP address-based section.IP address
First three section may include symbol " " between first three numeric string and these three numeric strings therein.Alternatively, before IP address
Three sections can also be including the symbol " " after first three numeric string.For IP address 221.217.241.***, first three section can
To be " 221.217.241 " or " 221.217.241. ".
Some clients, the individual client end that especially some operators's (such as China Unicom) are serviced, IP address
It may not be unalterable.Especially the 4th section of IP address is often variation.The 4th section of IP address may include it
In the last one numeric string.For IP address 221.217.241.***, the 4th section is * * *.Assuming that in a scene,
When client is distributed to particular server, it is contemplated that the 4th section of IP address.If the IP of client when distributing client
Address is changed, then will lead to the server that client is assigned to mistake, causes conversation.It is IP address-based
Client is distributed to particular server by first three section can guarantee each client distributing to particular server to a greater degree,
So that it is guaranteed that session is kept.
Optionally, client is distributed to particular server and is specifically included by first three IP address-based section in step S150
Step S151, step S152, step S153 and step S154.
In step S151, divisor is determined according to the number of all available servers.Firstly, determining whole available server
Total number.Divisor is determined according to the total number.For example, determining that the total number is divisor.Assuming that all available servers are in total
It is 10.Then it is determined that divisor is 10.Certainly, total number can also be more than or less than divisor.
In step S152, first three section of IP address is encoded, to obtain encoded radio.By the cataloged procedure, obtain

It is equipped with the processor compared with high primary frequency, some is configured with the processor of lower dominant frequency.Herein, the service that processing capacity can be given strong
Device assigns greater weight, and the weak server of processing capacity is given to assign smaller weight, with when loading distribution, by more client
The strong server of processing capacity is distributed to, less client is distributed into the weak server of processing capacity.
Determine that divisor can specifically include according to the number of all available servers in above-mentioned steps S151: according to each
The respective weights of available server and divisor is determined according to the number of all available servers.
In one example, the total number of available server is 10.Wherein the weight of the 10th server is 2, other
The weight of server is 1.Divisor can be determined as 11.In this example, divisor is greater than total number.As the IP of client
Client is respectively allocated to the 1st server to the 9th server when remainder is 1 to 9 to 11 modulus by the encoded radio of location.When
Client is distributed to the 10th server when remainder is 10 or 0 to 11 modulus by the encoded radio of the IP address of client.
In short, assigning different weights to the different server of processing capacity, the strong server of the processing capacity made is divided
With more clients, all available servers will be made to make the best use of everything, avoid computing resource waste.
Optionally, the step S150 of load allocation method 100 client distributed to based on unique identifier it is all
Before particular server in available server, method 100 further comprises: determining all available services based on server list
Device.Server in server cluster may break down, and causing can not be with client normal conversation.So in load point
With before, first determine available server, can guarantee server cluster preferably with client session.Determination operation can
To be based on server list, the identifier of all available servers can be listed in the server list.Server can be arranged
Table is stored on server administrators, to when needed, can take and determine all available services based on server list
