Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment set forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
In prior art, when carrying out load and distributing, different servers may be given by the different request dispatching of the same session of certain load, cause conversation thus.In description herein, load can be client.Such as, in certain client, user have input the username and password of login, does shopping to log in related web site.Logging request corresponding to this register may be assigned with and give server A.Server A saves this session by this logging request thus.When next user does shopping at this related web site, the request corresponding to this shopping operation may be assigned with and give server B, and server B does not have any information of this session.For server A, although it saves this session, probably because do not receive any request from client within a predefined time limit, cause conversation.
In order to carrying out remaining session when load distributes, according to an aspect of the present invention, provide a kind of load allocation method.Fig. 1 shows the indicative flowchart of load allocation method 100 according to an embodiment of the invention.As shown in Figure 1, load allocation method 100 comprises step S110, step S130 and step S150.
In step s 110, the session request from client is received.
Session (session) is the sequence of unbroken request between client and server and response.User end to server sends request.After server receives request, send the response to request to client.
The request first that user end to server sends is the request needing to create session.This asks to be the beginning counted in logic multiple request first.Ask first according to this, server can obtain the special identifier symbol of client.That is, server starts the request remembering this client and this client.Such as, when user logs in or add commodity in shopping cart, a session is just started.Server can carry out identify customer end according to session, such as can use the user name password that session level variable record active user has inputted, so just send request without the need to user at every turn and all re-entered, can also be used to record some other the information relevant with current this time session.When the clear and definite end session of client or server do not receive any request from client within a predefined time limit, session just finishes.When after conversation end, server just have forgotten the request of this client and this client.
Particularly, user opens a browser, accesses some webpages (web) website, clicks multiple hyperlink in this web site, and the multiple web resource of access services device, then closes browser, and whole process can be referred to as a session.Once close browser, when reopening browser, again can not utilize last session, having needed a newly-built session.In brief, session is the once call between client and server, such as, to utilize the mode of browser to realize.
As mentioned above, a session may comprise multiple request.In this step, the request belonging to special session from client can be received.This request received can be ask first, may not be and asks first.
In step s 130, which, according to session request, obtain the unique identifier of client.
Each session request comprises the information of the unique identifier about client.Thus, server can determine client according to session.According to received session request, server can obtain the unique identifier of client.This unique identifier identifies this session request and comes from which client.
Alternatively, unique identifier is Internet protocol (IP) address of client, such as 221.217.241.***.Usually, session request comprises the IP address of client.The IP address of each client is relatively-stationary, and it may be used for identifying client.Utilize IP address to be very convenient and practicality as the unique identifier of client, it can identify client exactly, thus the smooth realization of assured plan.
Be appreciated that except IP address, unique identifier also can be other identification informations of client, as long as this identification information can identify client uniquely.
In some instances, client can visit destination server by proxy server.Destination server is the server that client expects session with it.In these examples, proxy server can by the session request forward of client to destination server, and destination server obtains the unique identifier of client via proxy server thus.
In step S150, based on unique identifier client distributed to the particular server in all available servers.
This particular server is the server for this client service.This particular server can be determined according to the unique identifier of client.Each unique identifier unique identification client, thus, can determine each client to distribute to specific server.
In above-mentioned load allocation method 100 of the present invention, the unique identifier of client is utilized to set up mapping relations one by one between client and particular server, thus multiple client can distributed in the process of different operating unit, ensure by particular clients, the request dispatching that belongs to same session to same server, keep session thus.
Alternatively, client to be distributed to based on unique identifier at the step S150 of above-mentioned load allocation method 100 in the particular server in all available servers, unique identifier can be the IP address of client.In step S150, based on any information in IP address, client can be distributed to particular server.Such as, according to last position of IP address, client can be distributed to particular server.Can be that the client of even number distributes to server A by last of IP address, be that the client of odd number distributes to server B by last of IP address.
Alternatively, in step S150, client is distributed to particular server by first three section IP address-based.First three section of IP address can comprise the symbol ". " between first three numeric string wherein and this three numeric strings.Or first three section of IP address can also comprise the symbol ". " after first three numeric string.For IP address 221.217.241.***, its first three section can be " 221.217.241 " or " 221.217.241. ".
Individual client's end that some client, particularly some operators (such as CHINAUNICOM) are served, its IP address may not be unalterable.Particularly the 4th section of IP address is often change.The 4th section of IP address can comprise last numeric string wherein.For IP address 221.217.241.***, its 4th section is * * *.Suppose in a sight, when client is distributed to particular server, consider the 4th section of IP address.If the IP address of client there occurs change when distributing client, so by causing server client being assigned to mistake, cause conversation.Client is distributed to particular server and each client can be ensured to a greater degree to distribute to particular server by first three section IP address-based, thus guarantees that session keeps.
Alternatively, in step S150, client is distributed to special services implement body and is comprised step S151, step S152, step S153 and step S154 by first three section IP address-based.
In step S151, according to the number determination divisor of all available servers.First, total number of whole available server is determined.According to this total number determination divisor.Such as, determine that this total number is divisor.Suppose that all available servers are 10 altogether.So determine that divisor is 10.Certainly, total number can also be greater than or less than divisor.
In step S152, first three section of IP address is encoded, to obtain encoded radio.By this cataloged procedure, obtain one, with IP address, there is the encoded radio of mapping relations one by one.Such as IP address 221.217.241.***, the array of wherein first three section can be become encoded radio 221217241.
In step S153, by encoded radio divided by divisor, to obtain remainder.That is modulo operation is carried out to encoded radio.Such as, by 221217241 divided by 10, obtaining remainder is 1.
In step S154, based on remainder determination particular server.Particularly, be in the example of divisor in total number, the 1st server can determined in server according to remainder 1 is particular server.Be appreciated that if remainder is 0, so can determine that in server, the 10th server is particular server.
The implementation of above-mentioned steps S150 is fairly simple, and each client can be mapped to a unique particular server, thus ensures that session is not interrupted.
Alternatively, first three section of IP address is carried out encoding and is specifically comprised by above-mentioned steps S152: generate encoded radio, to represent this IP address according to numeral in first three section of IP address.
As mentioned above, in the present invention's example, directly by the digital jointing in first three section of IP address together, a number is formed using as encoded radio.Such as, for IP address 221.217.241.***, this encoded radio can be 221217241.
In another example of the present invention, first by the digital jointing in first three section of IP address together, then according to unalterable rules change this through splicing number in numeral, to obtain encoded radio.Specifically comprise the following steps: 1) by the 5th figure place and the 2nd figure place reversing of position; 2) the 3rd figure place is added particular value, such as 5.For IP address 221217241, first exchange the 5th figure place wherein and the 2nd figure place, obtain numeral 221247211; Then the 3rd figure place is added 5, obtain encoded radio 221247711 thus.
Alternatively, at above-mentioned steps S152 first three section of IP address carried out encoding and specifically comprise: Hash operation is carried out to first three section of IP address, and determines that obtained cryptographic Hash is encoded radio.
The binary value of random length can be mapped as the binary value of shorter regular length by Hash operation, and the binary value of this regular length is called cryptographic Hash.For any one binary value, its cryptographic Hash be one piece of data uniquely and extremely compact numeric representation form.So, can using the Hash operation result of first three section of IP address as encoded radio.Alternatively, cryptographic Hash can be the binary value of 12 to 16.
Hash operation can be regarded as a kind of cryptographic calculation.In step S152, perform the Hash operation of first three section to IP address, load allocation method can be made not easily to be cracked by bad personages such as hackers.That is, other people will be not easy to determine how client is distributed to particular server, avoid its attack to server system, thus improve the fail safe of system.
Alternatively, above-mentioned load allocation method 100 comprises for each available server further, according to disposal ability for it gives respective weights.Wherein, the size of weight is directly proportional to the disposal ability of server.The disposal ability of available server can be different.Than if any server possible configuration have processor compared with multinuclear, the processor being configured with less core had, the processor be configured with compared with high primary frequency had, the processor being configured with lower dominant frequency had.Here, give larger weight can to the server that disposal ability is strong, the server weak to disposal ability gives less weight, with when load distributes, more client is distributed to the strong server of disposal ability, less client is distributed to the weak server of disposal ability.
Number determination divisor according to all available servers in above-mentioned steps S151 can specifically comprise: according to the respective weights of each available server and according to the number determination divisor of all available servers.
In one example, total number of available server is 10.Wherein the weight of the 10th server is 2, and the weight of other servers is 1.Divisor can be defined as 11.In this example, divisor is greater than total number.When the encoded radio of the IP address of client is to 11 deliverys, when remainder is 1 to 9, client is distributed to respectively the 1st server to the 9th server.When the encoded radio of the IP address of client is to 11 deliverys, when remainder is 10 or 0, client is distributed to the 10th server.
In a word, give different weights to the server that disposal ability is different, the server that the disposal ability made is strong is assigned with more client, all available servers will be made to make the best use of everything, avoid computing resource waste.
Alternatively, at the step S150 of load allocation method 100 before based on unique identifier client being distributed to the particular server in all available servers, method 100 comprises further: determine all available servers based on server list.Server in server cluster may break down, cause cannot with client normal conversation.So, load distribute before, first determine available server, can Deterministic service device cluster better with client session.This determination operation based on server list, can list the identifier of all available servers in this server list.Server list can be stored on server administrators, thus when needed, can take and determine all available servers based on server list.
Alternatively, before determining all available servers based on server list, method 100 comprises step S101, step S102 and step S103 further.In step S101, send message to Servers-all.Monitoring request message can be sent by server administrators to all servers, can normally work so that monitor server is current.In step s 102, the feedback message of described Servers-all is received.If any server fault, then it correctly may not send feedback message.Thus, the correct feedback message from failed server will do not received.In step s 103, according to received feedback message determination server list.Particularly, can judge whether to have have received the feedback message from each server.Then, in all feedback messages, determine correct feedback message wherein from server.Finally, above-mentioned server list is generated according to the identifier of the server sending correct feedback message.
By sending monitoring request message and receiving the operating state that feedback message determines server, the work state information of server can be obtained more exactly, and then ensure client to be distributed to the server that can normally work, ensure that carrying out smoothly of the session of client and server.
