Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Note, below in conjunction with accompanying drawing and
The aspects that specific embodiment describes is only exemplary, and is understood not to protection scope of the present invention
Carry out any restriction.
Fig. 1 shows the block diagram of agency plant 100 according to an aspect of the present invention.As it is shown in figure 1,
Agency plant 100 can include domain name resolution server 101, proxy server 121,122 and server
Cluster 131,132.
User initiates an access request via client.Here client can be web browser, APP
Software such as wechat etc..First the access request initiated via client is entered via domain name resolution server 101
Row domain name mapping.Domain name resolution server 101 is responsible for resolving to proxy server 121,122 access request
In one.
According to an aspect of the present invention, agent functionality is performed by " region ".Proxy server 121,
122 are deployed in different geographical, and server cluster 131,132 is also deployed in different regions.Shown in Fig. 1
Example in, proxy server 121 and server cluster 131 are deployed in identical region 1；Agency
Server 122 and server cluster 132 are deployed in identical region 2.
In the example shown in Fig. 1, illustrate only two regions, region 1, region 2, the most only illustrate
The proxy server of the two region and server cluster, but, it will be understood by those skilled in the art that
Can exist and plural region, and each region are disposed corresponding proxy server and server set
Group, such as, deposit the proxy server 12n being deployed in the n of region and server cluster 13n (wherein n > 2) (not
Illustrate).
In one embodiment, domain name resolution server 101 can initiation address based on access request determine by
Which proxy server is this access request resolve to.Such as, domain name resolution server 101 can be asked accessing
Solving and analyse to first agent's server, wherein the initiation address of this access request falls at this first agent's server
Residing region.
As example, this first agent's server can be proxy server 121, i.e. domain name resolution server
Access request is resolved the proxy server 121 to region 1 by 101.
Proxy server 121 such as receives this access request by monitoring 80 ports.Proxy server 121
Can determine the server cluster in first-selected for access request agency region by configuration information based on self.Configuration letter
Can store first-selected region in breath, so-called first-selected region refers to that proxy server 121 is preferential by access request
Act on behalf of the server cluster to this first-selection region.Configuration information can also store its that sort by priority
The sorted lists of his region.
As example, the preferred region in the configuration information of next proxy server of normal condition is this agency
The region that server self is residing.Such as proxy server 121, its first-selected region is region 1,
For proxy server 122, first-selected region is region 2.Certainly, the first-selected region in configuration information
Can change, the such as server cluster in first-selected region occur the machine of delaying cannot normal response time, permissible
The first-selected region of change, this is described in detail below.
In the example shown in Fig. 1, proxy server 121 can be based on own configuration information by access request generation
Manage the server cluster 131 to region 1.
Containing multiple servers in server cluster 131, such as server A, B, C, D, the most only show
Go out 4 servers, however it will be appreciated that and can there is more server.
Proxy server 121 can be based on load balancing by the clothes in access request agency to first-selected region
The server in server cluster 131 in business device cluster i.e. region 1.
Conventional load balancing includes following several types:
Repeating query equilibrium (Round Robin): the request of automatic network each time is distributed in inside in turn
Server, then restarts from 1 to N.All services that this kind of equalization algorithm is suitable in server group
Device has identical software and hardware configuration and the situation of average service request relative equilibrium.
Weight repeating query equilibrium (Weighted Round Robin): according to the different disposal ability of server,
To the weights that each server-assignment is different so that it is the service request of corresponding weight value number can be accepted.Such as:
The weights of server A are designed to 1, and the weights of B are 3, and the weights of C are 6, then server A, B,
The service receiving 10%, 30%, 60% respectively is asked by C.This kind of equalization algorithm can ensure that high performance
Server obtains more utilization rate, it is to avoid the server load of low performance is overweight.
Stochastic Equilibrium (Random): multiple services that the request carrying out automatic network is randomly assigned in inside
Device.
Weight Stochastic Equilibrium (Weighted Random): this kind of equalization algorithm is similar to weight Round-Robin Algorithm,
It it is but a process randomly choosed when processing request and sharing.
Response speed equilibrium (Response Time): load-balancing device sends one to internal each server
Individual probe requests thereby (such as Ping), then according to server each in inside to the fastest response of probe requests thereby time
Between determine which station server come customer in response end service request.This kind of equalization algorithm can preferably reflect
The current operating conditions of server, but this fastest response time only refer only to load-balancing device and server
Between the fastest response time rather than fastest response time between client and server.
Minimum connection number equilibrium (Least Connection): the service of request each time of client is at server
Residence time there may be bigger difference, along with longer working time, if use simple repeating query or
Stochastic Equilibrium algorithm, the connection process on each station server may produce and differ greatly from, not reach
To real load balancing.The each station server needing load in inside is had by minimum connection number equalization algorithm
One data record, the connection quantity that record this server current is processing, please when there being new service to connect
When asking, by current request is distributed to connect the server that number is minimum, equilibrium is made to more conform to practical situation,
Load more equalizes.The request service processed when this kind of equalization algorithm is suitable for long, such as FTP.
Disposal ability equalizes: this kind of equalization algorithm will service request assignment to inside processes load (according to
Server CPU model, CPU quantity, memory size and current connect the conversions such as number and form) the lightest clothes
Business device, it is contemplated that the disposal ability of internal server and current network operation conditions, so this kind all
Account method the most accurate, be especially suitable for applying to the situation of layer 7 (application layer) load balancing
Under.
DNS response equilibrium (Flash DNS): on internet, either HTTP, FTP or its
Its service request, client is typically all and finds the definite IP address of server by domain name mapping.
Under this equalization algorithm, office receives the territory of same client at the load-balancing device of diverse geographic location
Name analysis is asked, and within the same time, this domain name mapping is become the IP address of respective corresponding server (i.e.
With this load-balancing device in the IP address of the server in geographical position, same position) and return to client,
Then request service is continued in the domain name mapping IP address to receive at first by client, and ignores other IP
Address response.In the case of kind of a balance policy is suitably applied in GSLB, to local load balancing
It is nonsensical.
Access request can be acted on behalf of to server cluster by such as proxy server 121 based on load balancing
Server A in 131, if server A response abnormality, then can be again based on load balancing will access
Other servers to this server cluster 131 are acted on behalf of in request, if response is the most abnormal, the most again act on behalf of
Next server to this server cluster 131, repeats this operation until access request obtains normal response.
In extreme circumstances, if the Servers-all in the server cluster in first-selected region all can not normally ring
Should, then proxy server 121 can be based on configuration information by the server in access request agency to another region
Cluster, such as configuration information medium priority are only second to the server cluster in next region of first-selected region.Make
For example, such as, access request can be acted on behalf of the server cluster to region 2 by proxy server 121
132。
If server cluster 2 can provide normal response, then proxy server 121 can revise configuration information with
Change first-selection region into region 2.More preferably, when the server cluster 131 in region 1 recovers normal, generation
The first-selected region of reason server 121 can change back region 1 again.
Access request generally comprises head portion and main part.As discussed previously, access request is likely
Sent, now, as the information of the head portion of access request is by network platforms such as wechat platforms
, it is impossible to as the sign of some normal load strategies.
In the present invention, proxy server can include data base and parsing module (not shown).Data
Storehouse can prestore the request form of multiple request type.Parsing module can be by searching data base with root
The main part of access request is resolved by the request form asked according to this user, to obtain ID,
Thus can be as the mark of load balancing.
Fig. 2 shows the flow chart of Proxy Method 200 according to an aspect of the present invention.As in figure 2 it is shown,
Proxy Method 200 can comprise the following steps that
In step 201: access request is performed domain name mapping, access request is resolved to multiple agency services
First agent's server in device, the plurality of proxy server is deployed in different regions.
This parsing can be that launch position based on access request is carried out, the initiation of such as this access request
Position falls in the first region residing for first agent's server.
In step 202: by first agent's server configuration information based on self by access request agency to first
Server cluster in selection of land territory.
Can store first-selected region in configuration information, so-called first-selected region refers to that proxy server please by access
Ask preferential agency to the server cluster of this first-selection region.Configuration information can also store and according to priority arranged
The sorted lists of other regions of sequence.As example, the configuration information of next proxy server of normal condition
In preferred region be the residing region of this proxy server self.
Further, first agent's server can be based on load balancing by the most first-selected for access request agency ground
A server in server cluster in territory.As it was previously stated, the load balancing often having can include repeating query
Equilibrium, weight repeating query equilibrium, Stochastic Equilibrium, response speed equilibrium, the equilibrium of minimum connection number, disposal ability
Equilibrium, DNS response equilibrium etc..
If the server response abnormality acted on behalf of, then it is again based on load balancing and access request is acted on behalf of
Other servers in server cluster to first-selected region are until access request obtains normal response.
If the equal response abnormality of Servers-all in the server cluster in this first-selection region, then by first agent
Server configuration information based on self is by the server cluster in access request agency to another region, such as
Configuration information is positioned at the server cluster of the next region of first-selected region according to prioritization.
Normally rung in server cluster and the access request that access request is acted on behalf of to another region
After should, revise this configuration information this another region to be configured to first-selected region.Preferably, can be at this
Server cluster in first region can with normal response time, selection of land territory headed by the first region is changeed back.
In one example, the main part of access request can be resolved to obtain user by first agent's server
ID, for the mark of load balancing.Such as, first agent's server can be based on locally stored pass
Request form in access request performs parsing to the main part of access request.
Fig. 3 shows the block diagram of agency plant 300 according to a further aspect in the invention.
As it is shown on figure 3, agency plant 300 can include domain name resolution server 301, proxy server 321,
322 and server cluster 331,332.Shown in Fig. 3 two proxy server 321,322 and
Two server clusters 331,332 are only examples, in practice, can exist a proxy server and
One server cluster, it is also possible to there is the proxy server more than two and the server set more than two
Group.
According to an aspect of the present invention, each server cluster can include two server groups, one of them clothes
Business device group is for providing the formal publisher server group of the service of access, and another group is pre-for server updating
Cloth server group.These two groups of server groups are duplicate, and the role differing only in both is different, i.e.
The role of each server group is carried out between " formal publisher server group " and " pre-publisher server group "
Switching.When a server group is " formal publisher server group ", another group is then " pre-issuing service
Device group ", and originally ought switch to for the server group of " formal publisher server group " role and " issue clothes in advance
Business device group " time, original server group for " pre-publisher server group " role switches to simultaneously " formally to be sent out
Cloth server group ".
As a example by example in Fig. 3, server cluster 331 includes two server groups 3311,3312.
Server group 3311 and server group 3312 are originally used for two server groups mapped each other, and i.e. both are completely
Identical.But be used for providing a user with access response by server group 3311, another server group 3312 is not
For providing a user with access response, but for server updating.Now, server group 3311
Being referred to as formal publisher server group, now server group 3312 can be described as pre-publisher server group.
In one example, in server group 3312 is the time undertaking pre-publisher server group role,
If needing server is made any upgrading, the most not to the server group undertaking formal publisher server group role
3311 do any operation, but only upgrade server group 3312, and server updating here is permissible
It is the renewal of server content, or the amendment of server configures.
After the server group 3312 undertaking pre-publisher server group role is upgraded, server group 3312
Can be formal publisher server group, correspondingly, server group 3311 from the role switching of pre-publisher server group
Then the role switching from formal publisher server group is pre-publisher server group, and both realize role exchange.
In another example, in server group 3312 is the time undertaking pre-publisher server group role,
If needing server is made any upgrading, first server group 3312 can be switched to formal server group,
Server group 3311 is switched to pre-publisher server group simultaneously；Then, server group 3311 is risen
Level.
After upgrading server group 3311, server group 3312 switches to pre-issue to take again
Business device group, the server group 3311 after upgrading switches to formal server group.
It should be noted that the above-mentioned passive switching switched between server group.But it is all right in the present invention
In the case of formal server group is all abnormal, pre-publisher server group is switched to formal server group,
And formally server group switches to pre-publisher server group.The follow-up pre-issue clothes that can also regularly detect exception
Whether business device group recovers normal, after treating that pre-publisher server group is recovered normally, recovers to issue clothes in advance normally
Business device switches to formal server group, and formal server group switches back into pre-publisher server group again.
User initiates an access request via client.Here client can be web browser, APP
Software such as wechat etc..First the access request initiated via client is entered via domain name resolution server 301
Row domain name mapping.Domain name resolution server 301 is responsible for resolving to proxy server 321,322 access request
In one, such as proxy server 321.Proxy server 321 can will be visited by configuration information based on self
Ask request agency the formal publisher server group to a server cluster, such as server cluster 331.
From the foregoing, it will be observed that proxy server always by access request agency to server cluster formally issues clothes
Business device group.Always pass through upgrading due to formal publisher server group and be provided that the server of normal access response
Group, therefore, access request can obtain normal response.Although additionally, formal publisher server group is in service
Switch between two server groups of device cluster, but this switching is sightless for a user, therefore,
The upgrading of server can be with seamless switching, it is not necessary to restart server.
In the case of there is multiple proxy server and multiple server cluster, can come by " region "
Perform agent functionality.Such as, proxy server 321,322 is deployed in different geographical, server cluster 331,
332 are also deployed in different regions.In examples as shown in figure 3, proxy server 321 and server
Cluster 331 is deployed in identical region 1；Proxy server 322 and server cluster 332 are deployed in phase
Same region 2.
In one embodiment, domain name resolution server 301 can initiation address based on access request determine by
Which proxy server is this access request resolve to.Such as, domain name resolution server 101 can be asked accessing
Solving and analyse to first agent's server, wherein the initiation address of this access request falls at this first agent's server
Residing region.
Proxy server 321 such as receives this access request by monitoring 80 ports.In one example,
Proxy server 321 can determine the service in first-selected for access request agency region by configuration information based on self
Device cluster.Can store first-selected region in configuration information, so-called first-selected region refers to proxy server 321
Access request is preferentially acted on behalf of the server cluster to this first-selection region.Configuration information can also store by
The sorted lists of other regions of prioritization.
As example, the preferred region in the configuration information of next proxy server of normal condition is this agency
The region that server self is residing.Such as proxy server 321, its first-selected region is region 1,
For proxy server 322, first-selected region is region 2.
In examples as shown in figure 3, proxy server 321 can be based on own configuration information by access request generation
Manage the server cluster 331 to region 1.
Proxy server 321 can be based on load balancing by the clothes in access request agency to first-selected region
The formal publisher server group such as server group in server cluster 331 in business device cluster i.e. region 1
Server in 3311.
Conventional load balancing can include repeating query equilibrium, weight repeating query equilibrium, Stochastic Equilibrium, response speed
Degree equilibrium, the equilibrium of minimum connection number, disposal ability equilibrium, DNS response equilibrium etc..
Access request can be acted on behalf of to server cluster by such as proxy server 321 based on load balancing
Server A in formal publisher server group 3311 in 331, if server A response abnormality, then can be again
Secondary based on load balancing by access request agency to other servers in this server group 3311, if
Response is the most abnormal, the most again acts on behalf of next server to this server group 3311, repeats this operation
Until access request obtains normal response.
In extreme circumstances, if all clothes in the formal publisher server group 3311 of server cluster 331
Business device all can not normal response, then proxy server 321 can based on configuration information by access request agency under
In one region, such as configuration information medium priority is only second to the server cluster in next region of first-selected region
In formal publisher server group.As example, access request can be acted on behalf of extremely by such as proxy server 321
Formal publisher server group in server cluster 332 in region 2.If now in server cluster 332
Formal publisher server group be server group 3321, then by access request act on behalf of to server group 3321,
Otherwise act on behalf of to server group 3322.
In more extreme cases, if the formal publisher server group of the server cluster in all regions is the loudest
Should be abnormal, then access request can be acted on behalf of the server set to first-selected region by proxy server 321 again
The pre-publisher server group of group, such as the pre-publisher server group 3312 in the server cluster 331 of region 1.
If the pre-publisher server group 3312 in the server cluster 331 of this region 1 also cannot normal response,
Then can be by access request agency to next region, such as configuration information medium priority is only second to first-selected region
Pre-publisher server group in server cluster in next region, the server cluster 332 of such as region 2
In pre-publisher server group 3322 till access request obtains normal response.
In the case of the formal publisher server group of Servers-all cluster all delays machine, follow-up when can be spaced
Between whether detect formal publisher server group normal, if formally recovered, it is possible to switch back into and formally issue clothes
Business device group.
As discussed previously, access request generally comprises head portion and main part.Access request is likely
Being sent by wechat platform, webservice etc., now, the information of the head portion of access request is
The same, it is impossible to as the sign of some normal load strategies.
In the present invention, proxy server can include data base and parsing module (not shown).Data
Storehouse can prestore the request form of multiple request type.Parsing module can be by searching data base with root
The main part of access request is resolved by the request form asked according to this user, to obtain ID,
Thus can be as the mark of load balancing.
Fig. 4 shows the flow chart of Proxy Method 400 according to an aspect of the present invention.As shown in Figure 4,
Proxy Method 400 can comprise the following steps that
In step 401: access request is performed domain name mapping, access request is resolved to first agent's service
Device.

This first agent's server in business device, these multiple proxy servers are deployed in different regions, each region
Inside it is deployed with corresponding server cluster.The launch position of this access request falls at described first agent's server
In the first residing region
In step 402: by this first agent's server configuration information based on self, access request is acted on behalf of extremely
Formal publisher server group in first server cluster, this first server cluster includes for providing access
The formal publisher server group serviced and the pre-publisher server group being used for server updating, this pre-issuing service
Device group switches to formal publisher server group to service for providing to access after upgrading, and formally issues
Server group correspondingly switches to pre-publisher server group for server updating.
In the example of one server cluster of each region configuration, this first server cluster can be this
Server cluster in first-selected region in the configuration information of one proxy server.
Further, first agent's server can based on load balancing by access request agency to this first
The server in formal publisher server group in server cluster.Conventional load balancing can include wheel
Follow equilibrium, weight repeating query equilibrium, Stochastic Equilibrium, response speed equilibrium, the equilibrium of minimum connection number, process energy
Power equilibrium, DNS response equilibrium etc..
If the equal response abnormality of Servers-all in the formal publisher server group of first server cluster, then may be used
By first agent's server configuration information based on self by the service in access request agency to next region
Formal publisher server group in device cluster is until access request obtains normal response.
In extreme situations, if the formal publisher server group of the server cluster in all regions all responds
Abnormal, then by first agent's server configuration information based on self, access request can be acted on behalf of to first service
Pre-publisher server group in device cluster.
In more extreme cases, if the Servers-all in the pre-publisher server group of first server cluster
All response abnormality, then can act on behalf of supreme by access request by first agent's server configuration information based on self
State the pre-publisher server group in the server cluster in next region, repeat this operation until access request obtains
To normal response.
In the case of the formal publisher server group of Servers-all cluster all delays machine, follow-up when can be spaced
Between whether detect formal publisher server group normal, if formally recovered, it is possible to switch back into and formally issue clothes
Business device group.
In one example, the main part of access request can be resolved to obtain user by first agent's server
ID, for the mark of load balancing.Such as, first agent's server can be based on locally stored pass
Request form in access request performs parsing to the main part of access request.
