Flow identifies, and then improves flow switch efficiency；On the other hand, occur in the application state for detecting the computer room rear end different
During reason condition, Automatic dispatching is carried out to the flow of the computer room by the front end inlet of the computer room, solves computer room entrance hair
The problem of causing customer flow to be lost during changing, realize the state holding across computer room, it is ensured that the continuity of business, improve
Reliability, more preferable experience is brought for user.
Next, the traffic scheduling method in this example embodiment will be further illustrated.
In step S210, it is identified according to user request of the field identification of multiple computer rooms to a client, and really
The computer room that the fixed client accesses first.
In this exemplary embodiment, network reliability is influenceed in order to solve the problems, such as and avoid unit room to break down, can
To carry out more computer room deployment to a certain business.For a product such as electric business system, inside is to need many subsystems
Assist together.Its more computer room deployment scenario can be described as：Assuming that computer room 1 is deployed in using a, can in the other application of computer room 1
To call the interface using a, then also many subsystems are to be deployed in computer room 2, and the application in computer room 2 is also required to calling and arrived
Using a, then when a in the application call computer room 1 so in computer room 2 is applied, just have because the delay problem caused by computer room.
If the query rate QPS per second of system requires very high, then preferably should be also deployed in computer room 2 using a, so as to carry out multimachine
Room is disposed.It is required for calling using e and d and apply a, then we also can disposes application a in computer room 2, thus can be with
Avoid across computer room delay problem.
Multiple computer rooms can be built according to the actual requirements, the flow scheduling process in this example between two computer rooms
Exemplified by illustrate.It can be provided first for each computer room or configure a field identification, the field identification for example may be used
Think cookie field identifications either http.Cookie is stored in the variable in the client of visitor, whenever same
When client is by some page of browse request, this cookie will be sent.Cookie can apply to preservation user and step on
Record state.Such as user id is stored in a cookie, so avoided the need for again when user accesses the page next time
Log in.In addition, cookie can also set the login term of validity, and after more than the term of validity is logged in, cookie will be automatic
Disappear.Because cookie operates in client, therefore can be by specific Website page JavaScript
Cookie field identifications described in setcookie function setups, it can also be set by application program backstage.
Because each computer room has unique corresponding field identification, therefore the user of a certain client can be asked to carry out
Parsing identification, so as to can quickly determine the computer room that the client accesses first according to analysis result.Client is for example
It can be the electronic equipment that mobile phone, computer, IPAD etc. can connect network.
Wherein it is determined that the specific steps for the computer room that the client accesses first can include：
Asked by user described in dns resolution, and the attribute field in user request determines the client
The computer room accessed first.
For example, if some core application deploys Hadoop processing clusters in computer room 1 and computer room 2 respectively.Client
By dns resolution when holding the A to access for the first time, it is determined that had access to computer room 1, then client request corresponding to customer end A is such as
Following content occurs in http request head：“Set-Cookie:CLUSTERENV=HZIDC；Domain=.xx.163.com；
Path=/；Expires=Tue, 15-Aug-201715:46:37GMT”.Then all can be with this when customer end A accesses
Computer room 1 will be all accessed after CLUSTERENV attribute cookie, i.e. customer end A.For example, the application scenarios with reference to shown in figure 1,
If one needs the user for carrying out the client of payment transaction to ask to include HZIDC corresponding to the computer room of Hangzhou inside cookie,
Even if the user asks current accessed Guangzhou computer room, also flow can be dispatched to Hangzhou computer room by Intranet and carry out payment transaction.
In this example, the computer room entrance of cookie fields identification user's request in being asked by user, correlation is avoided
To the dependence of DNS systems in technology, therefore the slowly caused poorly efficient influence of DNS systems is also reduced, quickly cut to realize
Change planes room and flow scheduling makees basis.
In step S220, the field identification in all user's requests of the client is parsed, and will be each described
User's request dynamic is sent to corresponding computer room rear end.
In the present example embodiment, field identification can be understood as in above-mentioned steps as the field of each computer room configuration
Mark, the field identification in all users request of the client can be parsed by front end web portal cluster, and according to right
All user's requests are dynamically distributed to corresponding computer room by the attribute field in the analysis result of the field identification successively, with
Computer room rear end is set to handle the user's request received.Such as each user can be asked to distribute one by one in chronological order
To different back-end servers, each user can also be asked by the hash results distribution for accessing IP or by back-end services
The response time of device carrys out distributing user request, and this example is not particularly limited to this.
Specifically, each http that web portal cluster in front end can be sent by dns resolution system analysis client please
Ask, and find out the CLUSTERENV fields in each http request analysis result cookie of the client, then according to each
Mapping relations between individual computer room backend application cluster and each user request, will client corresponding with CLUSTERENV fields
Http request dynamic be distributed to corresponding to computer room rear end.
In step S230, when abnormal conditions occurs in the application state for detecting the computer room rear end, entered by front end
Mouth carries out Automatic dispatching to the flow of the computer room.
In the present example embodiment, the application state of computer room rear end occur going offline etc. abnormal conditions when, in order to ensure industry
Business or the continuity of application, it usually needs switching computer room, such as the network of cell-phone customer terminal can be switched to by 4G data
WiFi.Can now depth customization be carried out to front end web portal, so as to realize that user keeps across the state of computer room.For example, with
When family carries out net purchase, when having access to computer room 2 because of network change after user A login computer rooms 1, computer room 2, which can pass through to parse, to be used
The http request data at family, so as to which user A flow water conservancy diversion to be returned to the application cluster of the rear end of computer room 1.Similarly, in computer room 2
When network changes, front end web portal cluster can dynamically by originally by the cluster of computer room 2 handle user ask water conservancy diversion to
Computer room 1, so that it is guaranteed that the continuity of overall business.Due to computer room entrance as network changes, avoid user and log in shape
The problem of state is lost, improve the reliability of system.
Specifically, the flow to the computer room described in step S230, which carries out Automatic dispatching, to include：
The field identification in being asked according to the user is scheduled to the flow of the computer room.
In the present example embodiment, front end inlet can parse the field mark in user's request that a certain client is sent
Know, and according to the field identification by flow scheduling to the unique corresponding computer room of the field identification, so as to realize the accurate of flow
Scheduling.
Wherein, the field identification in being asked according to the client user is scheduled tool to the flow of the computer room
Body can include：
The mapping between the field identification and each computer room backend application cluster in being asked according to the user is closed
System, is scheduled to the flow of the computer room according to logic of propositions.
For example, CLUSTERENV fields corresponding to computer room 1 are GZIDC, and CLUSTERENV fields are corresponding to computer room 2
GZIDC is included inside BJIDC, the cookie for the http request that customer end A is sent, then according to the field identification and each machine
Mapping relations between room backend application cluster, the http request is distributed to computer room 1.Further, if a client
The user at end asks current accessed Guangzhou computer room, but the user asks to include HZIDC corresponding to the computer room of Hangzhou inside cookie,
Also flow can be dispatched by Intranet according to the mapping relations between the field identification and each computer room backend application cluster
To Hangzhou computer room.The method can not avoid computer room from abnormal conditions occur, therefore can not ensure the reliability of flow scheduling.
In order to avoid above mentioned problem, being adjusted automatically to flow corresponding to the computer room described in this exemplary step S230
Degree can also include：
The flow of the computer room is scheduled according to logic of propositions according to the application state of the computer room rear end.
In the present example embodiment, the flow of a certain computer room can be adjusted by the application state of computer room rear end
Degree.It can judge whether the application state of computer room rear end is abnormal, and unavailable shape is in backend application by test program first
During state, it can be adjusted automatically by front end inlet pair flow corresponding with the computer room according to the logic of propositions set in advance
Degree.Logic of propositions herein can be configured according to the actual requirements, for example, when computer room 1 is abnormal, the flow of computer room 1 is adjusted
Spend to computer room 2 or computer room 3.By the front end inlet of computer room in this example, and according to the application state pair of the computer room rear end
The flow of the computer room is scheduled, and avoids and dns resolution system is depended on unduly, so as to improve stream during switching computer room
Measure dispatching efficiency.
Specifically, in this example embodiment, the flow according to the application state of the computer room rear end to the computer room
Being scheduled according to logic of propositions to include：
When abnormal conditions occurs in application state in the first computer room rear end, the front end for only retaining first computer room enters
Mouthful；
When the client has access to the front end inlet of first computer room, ignore the word of the client
The flow is simultaneously imported the second computer room by flow scheduling information in segment identification；
The front end inlet of second computer room stops the flow scheduling to the rear end of first computer room.
In the present example embodiment, if the application state of the first computer room rear end is in down state or occurred whole
When body change can not service, then it can only retain the front end web portal cluster of the first computer room.Had access in any one client
During the first computer room entrance, because the front end web portal of the first computer room finds that the first computer room backend state is abnormal, therefore it can ignore
The information that field identification in user's request includes, the flow of the first computer room automatically imported or be dispatched to the second computer room, with
This simultaneously, the front end inlet of the second computer room will also stop the flow scheduling to the rear end of first computer room.In this example,
Scheduling of the flow between different computer rooms can be achieved by the application state of computer room rear end in front end web portal, ensure that business
Continuity.
For example, in the application scenarios shown in Fig. 1, the first computer room is Hangzhou computer room, and corresponding cookie is
HZIDC；Second computer room is Guangzhou computer room, and corresponding cookie is GZIDC.In Hangzhou, the business of computer room is temporarily unavailable or will
When moving back the computer room, flow scheduling can be carried out according to computer room backend application state.Specific flow is as follows：The computer room and wide in Hangzhou
When computer room 2 computer rooms in state all operate online, if the business of Hangzhou computer room will occur overall change and can not service, product or
Using that can select, all business clusters to Hangzhou computer room are offline, and only retain the front end web portal of Hangzhou computer room.
If user's request has access to Hangzhou computer room entrance, because the front end web portal of Hangzhou computer room finds Hangzhou machine
Room rear end is unavailable, then can actively ignore user and ask to require the information for being dispatched to Hangzhou computer room cluster in cookie, and actively
Flow is imported into Guangzhou computer room.The front end web portal of Guangzhou computer room can also find that Hangzhou computer room cluster is unavailable, and actively stopping will
Flow scheduling is to the rear end of Hangzhou computer room, so as to realize that the flow moment of all business, smoothly computer room was switched to Guangzhou from Hangzhou
The function of computer room.
In this example, front end web portal can carry out across the computer room scheduling of flow, phase according to the application state of computer room rear end
Than for prior art, in front end, web portal layer improves business fault-tolerance, more computer room applications when reducing backend services exploitation
Difficulty, improve the efficiency of flow scheduling between computer room.
Further, by the flow scheduling between different computer rooms, business phase mutual tolerance can be realized between multiple computer rooms
It is wrong, it is ensured that each user request that client is sent is affected all without the abnormal failure because of some computer room cluster.Example
