Description
Technical field
The present invention relates to Internet technology more particularly to network agent method and agency plants.
Background technique
Network agent function is the common internet function executed by proxy server, i.e. agency network user goes to take
Obtain the network information.Figuratively, proxy server is the terminal of the network information.Under normal circumstances, we use client,
Such as web browser must send out access request to be returned when directly removing to connect other Internet websites and obtaining the network information
It answers, then other side sends back information to come again.Proxy server is a service between browser and Web server
Device, after having it, browser is not directly to go to fetch webpage to Web server but issue request to proxy server.It visits
It asks that request can first be sent to proxy server, information required for browser is fetched by proxy server and sends your browsing to
Device.Moreover, most of proxy server all has the function of buffering, just as a big Cache, it has very big storage empty
Between, it is constantly obtained new in data storage to the memory of its machine, if the requested data of browser are in its machine
It is had existed on memory and is newest, then it is just not again from Web server access evidence, and directly will be on memory
Data transmission to the browser of user, can thus significantly improve surfing and efficiency.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.Note that below in conjunction with attached drawing and specifically real
The aspects for applying example description is merely exemplary, and is understood not to carry out any restrictions to protection scope of the present invention.
Fig. 1 is to show the block diagram of agency plant 100 according to an aspect of the present invention.As shown in Figure 1, agency plant
100 may include domain name resolution server 101, proxy server 121,122 and server cluster 131,132.
User initiates an access request via client.Here it is for example micro- that client can be web browser, APP software
Letter etc..The access request initiated via client carries out domain name mapping via domain name resolution server 101 first.Domain name mapping
Server 101 one of is responsible for parsing access request to proxy server 121,122.
According to an aspect of the present invention, by " region " Lai Zhihang agent functionality.Proxy server 121,122 is deployed in not
Same region, server cluster 131,132 are also deployed in different regions.In example shown in Fig. 1,121 and of proxy server
Server cluster 131 is deployed in identical region 1；Proxy server 122 and server cluster 132 are deployed in identical region
2。
It illustrate only two regions in example shown in Fig. 1, region 1, region 2 also only illustrate the two ground
The proxy server and server cluster in domain, however, it will be understood by those skilled in the art that more than two regions may be present,
And corresponding proxy server and server cluster are disposed in each region, such as deposits the agency service being deployed in the n of region
Device 12n and server cluster 13n (wherein n > 2) (not shown).
In one embodiment, domain name resolution server 101 can be determined based on the initiation address of access request by the access
Request analysis is to which proxy server.It is taken for example, domain name resolution server 101 can parse access request to first agent
Business device, wherein the initiation address of the access request falls in region locating for first agent's server.
As an example, first agent's server can be proxy server 121, i.e. domain name resolution server 101 will visit
Ask the proxy server 121 of request analysis to region 1.
Proxy server 121 for example receives the access request by monitoring 80 ports.Proxy server 121 can be based on certainly
The configuration information of body determines the server cluster acted on behalf of access request in preferred region.First choice is can store in configuration information
Region, so-called first choice region refer to that proxy server 121 is preferentially acted on behalf of access request to the server cluster of the first choice region.
The sorted lists of other regions sorted by priority can also be stored in configuration information.
As an example, the preferred region in the configuration information of lower proxy server of normal condition is the proxy server
Region locating for itself.Such as proxy server 121, preferred region is region 1, for proxy server 122
For, preferred region is region 2.Certainly, the preferred region in configuration information can be changed, such as the clothes in preferred region
Business device cluster occur delay machine can not normal response when, preferred region can be changed, this is described in detail below.
In example shown in Fig. 1, proxy server 121 can be acted on behalf of access request to region based on own configuration information
Server cluster 131 in 1.
Contain multiple servers, such as server A, B, C, D in server cluster 131, illustrates only 4 services here
Device, however it will be appreciated that may exist more servers.
Proxy server 121 can be acted on behalf of access request to the server cluster in preferred region based on load balancing
The server in server cluster 131 i.e. in region 1.
Common load balancing includes following several types:
Repeating query equilibrium (Round Robin): server in inside is distributed in the request for carrying out automatic network each time in turn, from
Then 1 to N restarts.The Servers-all that such equalization algorithm is suitable in server group has identical software and hardware configuration
And average service requests the case where relative equilibrium.
Weight repeating query is balanced (Weighted Round Robin): according to the different disposal ability of server, giving each clothes
Business device distributes different weights, can receive the service request of corresponding weight value number.Such as: the weight of server A is designed
Weight at 1, B is that the weight of 3, C is 6, then server A, B, C by receive respectively 10%, 30%, 60% service request.
Such equalization algorithm can ensure that high performance server obtains more utilization rates, avoid the server load of low performance overweight.
Stochastic Equilibrium (Random): the multiple servers request for carrying out automatic network being randomly assigned in inside.
Weight Stochastic Equilibrium (Weighted Random): such equalization algorithm is similar to weight Round-Robin Algorithm, but is locating
Reason request is a randomly selected process when sharing.
Response speed equilibrium (Response Time): load-balancing device issues a detection to internal each server and asks
(such as Ping) is asked, which platform server is then determined to the fastest response time of probe requests thereby according to server each in inside
Carry out the service request at customer in response end.Such equalization algorithm can preferably reflect the current operating conditions of server, but this is most fast
Response time only refers only to the fastest response time between load-balancing device and server, rather than between client and server
The fastest response time.
Minimum connection number is balanced (Least Connection): what the service of request each time of client was stopped in server
Time might have biggish difference, with longer working time, if using simple repeating query or Stochastic Equilibrium algorithm, it is each
Connection process on platform server, which may generate, to be differed greatly from, and does not reach real load balancing.Minimum connection number
Equalization algorithm has a data record to each server for needing load in inside, records the current server and is handling
Connection quantity current request will be distributed to the least server of connection number when there is new service attachment request, and make equilibrium
Actual conditions are more in line with, are loaded more balanced.The request service that such equalization algorithm is handled when being suitble to long, such as FTP.
Processing capacity is balanced: such equalization algorithm, which will distribute to service request, handles load (according to server in inside
CPU model, CPU quantity, memory size and current connection number etc. convert) most light server, due to consideration that internal
The processing capacity and current network operation conditions of server are especially suitable for so such equalization algorithm is comparatively more accurate
In the case where applying to layer 7 (application layer) load balancing.
DNS responds balanced (Flash DNS): on internet, either HTTP, FTP or other service requests,
Client is typically all that the exact IP address of server is found by domain name mapping.Under this equalization algorithm, divides and be in not
The domain name mapping request of the same client is received with the load-balancing device in geographical location, and this domain name within the same time
Be parsed into respective corresponding server IP address (i.e. with this load-balancing device the server in same position geographical location IP
Address) and return to client, then client will be serviced with the domain name mapping IP address received at first to continue request, and be ignored
Other IP address responses.In the case where kind of a balance policy is suitably applied in global load balancing, it is to local load balancing
Nonsensical.
Such as proxy server 121 can be acted on behalf of access request into server cluster 131 based on load balancing
Server A can be again based on load balancing and act on behalf of access request to the server set if server A response abnormality
Other servers in group 131, if response or exception, act on behalf of next server into the server cluster 131 again,
This operation is repeated until access request obtains normal response.
In extreme circumstances, if the Servers-all in server cluster in preferred region is all unable to normal response,
Proxy server 121 can be acted on behalf of access request to the server cluster in another region, such as with confidence based on configuration information
Priority is only second to the server cluster in next region of preferred region in breath.As an example, for example can proxy server 121
Access request can be acted on behalf of to the server cluster 132 in region 2.
If server cluster 132 is capable of providing normal response, proxy server 121 can modify configuration information with will be preferred
Region is changed to region 2.More preferably, when the server cluster 131 in region 1 restores normally, the preferred region of proxy server 121
Region 1 can be changeed back again.
Access request generally comprises head portion and main part.As discussed previously, access request, which is likely to be, to be passed through
The network platforms such as wechat platform issue, at this point, the information of the head portion of access request be it is the same, cannot function as some general
The mark of logical load strategy.
In the present invention, proxy server may include database and parsing module (not shown).It can be in database
Prestore the request format there are many request type.Parsing module can request by searching for database to be requested according to the user
Format parses the main part of access request, to obtain User ID, it is possible thereby to the mark as load balancing.
Fig. 2 is to show the flow chart of Proxy Method 200 according to an aspect of the present invention.As shown in Fig. 2, Proxy Method
200 can comprise the following steps that
In step 201: executing domain name mapping to access request, access request is parsed to the into multiple proxy servers
One proxy server, multiple proxy server are deployed in different regions.
The parsing can be the launch position based on access request to carry out, such as the launch position of the access request is fallen
In the first region locating for first agent's server.
In step 202: being acted on behalf of access request to preferred region based on the configuration information of itself by first agent's server
Interior server cluster.
Preferred region is can store in configuration information, so-called first choice region refers to that proxy server is preferential by access request
It acts on behalf of to the server cluster of the first choice region.The row of other regions sorted by priority can also be stored in configuration information
Sequence table.As an example, the preferred region in the configuration information of lower proxy server of normal condition is the proxy server
Region locating for itself.
Further, first agent's server can be acted on behalf of access request to preferred region based on load balancing
A server in server cluster.As previously mentioned, the load balancing often having may include that repeating query is balanced, weight repeating query is equal
Weighing apparatus, Stochastic Equilibrium, response speed are balanced, minimum connection number is balanced, processing capacity is balanced, DNS responds equilibrium etc..
If the server response abnormality acted on behalf of, is again based on load balancing and acts on behalf of access request to first choice
Other servers in server cluster in region are until access request obtains normal response.
If the equal response abnormality of Servers-all in the server cluster in the first choice region, by first agent's server
Access request is acted on behalf of to the server cluster in another region, such as according to excellent in configuration information based on the configuration information of itself
First grade sequence is located at the server cluster in next region of preferred region.
After access request being acted on behalf of to the server cluster in another region and access request obtains normal response,
The configuration information is modified to configure preferred region for another region.It preferably, can be in the server in first region
When cluster can be with normal response, selection of land domain headed by the first region is changeed back.
In one example, can by first agent's server parse access request main part to obtain User ID, with
In the mark of load balancing.For example, first agent's server can be based on the request lattice about access request being locally stored
Formula executes parsing to the main part of access request.
Fig. 3 is to show the block diagram of agency plant 300 according to another aspect of the present invention.
As shown in figure 3, agency plant 300 may include domain name resolution server 301, proxy server 321,322 and clothes
Business device cluster 331,332.Two proxy servers 321,322 and two server clusters 331,332 shown in Fig. 3 are only
It is example, in practice, may exist a proxy server and a server cluster, there may also be the agencies for being greater than two
Server and server cluster greater than two.
According to an aspect of the present invention, each server cluster may include two server groups, one of server group
To provide the formal publisher server group of access service, another group is the pre- publisher server group for server updating.This two
Group server group be it is duplicate, the role that difference both is only that is different, that is, the role of each server group is " formal
It is switched between publisher server group " and " pre- publisher server group ".When a server group is " formal publisher server
When group ", another group is then " pre- publisher server group ", and ought originally be that the server group of " formal publisher server group " role is cut
When being changed to " pre- publisher server group ", original server group for " pre- publisher server group " role is switched to " formal hair simultaneously
Cloth server group ".
By taking the example in Fig. 3 as an example, server cluster 331 includes two server groups 3311,3312.Server group 3311
Two server groups mapped each other are originally used for server group 3312, i.e., the two is identical.However by server group 3311
For providing a user access response, another server group 3312, which is not used in, provides a user access response, but for servicing
Device upgrading.At this point, server group 3311 can be described as formal publisher server group, server group 3312 can be described as pre- publication at this time
Server group.
It in one example, is in the time for undertaking pre- publisher server group role, if necessary in server group 3312
Any upgrading is made to server, then any operation is not done to the server group 3311 for undertaking formal publisher server group role, and
It is only to upgrade to server group 3312, server updating here can be update or the server of server content
The modification of configuration.
After the server group 3312 for undertaking pre- publisher server group role upgrades, server group 3312 can be from pre- hair
The role switching of cloth server group is formal publisher server group, and correspondingly, server group 3311 is then from formal publisher server
The role switching of group is pre- publisher server group, and the two realizes role exchange.
It in another example, is in the time for undertaking pre- publisher server group role, if needed in server group 3312
To make any upgrading to server, server group 3312 first can be switched to formal server group, while by server group
3311 are switched to pre- publisher server group；Then, server group 3311 is upgraded.
After upgrading to server group 3311, server group 3312 is switched to pre- publisher server group again,
Server group 3311 after upgrading is switched to formal server group.It should be noted that above-mentioned be switched between server group
Passive switching.But pre- publisher server group can also be switched in the case where formal server group whole exception in the present invention
For formal server group, and formal server group is switched to pre- publisher server group.It is subsequent periodically to detect the pre- of exception
Whether publisher server group is restored normally, after restoring normal to pre- publisher server group, restores normal pre- publisher server
It is switched to formal server group, and formal server group switches back into pre- publisher server group again.
User initiates an access request via client.Here it is for example micro- that client can be web browser, APP software
Letter etc..The access request initiated via client carries out domain name mapping via domain name resolution server 301 first.Domain name mapping
Server 301 one of is responsible for parsing access request to proxy server 321,322, such as proxy server 321.Agency
Server 321 can be acted on behalf of access request to a server cluster, such as server cluster 331 based on the configuration information of itself
Formal publisher server group.
From the foregoing, it will be observed that access request is always acted on behalf of the formal publisher server into server cluster by proxy server
Group.Since formal publisher server group always by upgrading and can provide the server group of normal access response, access is asked
Normal response can be obtained by asking.In addition, although formal publisher server group is cut between two server groups of server cluster
Change, but the switching be for a user it is sightless, therefore, the upgrading of server can not be needed again with seamless switching
Start server.
There are multiple proxy servers and multiple server clusters, agency can be executed by " region "
Function.For example, proxy server 321,322 is deployed in different geographical, server cluster 331,332 is also deployed in different ground
Domain.In examples as shown in figure 3, proxy server 321 and server cluster 331 are deployed in identical region 1；Agency's clothes
Business device 322 and server cluster 332 are deployed in identical region 2.
In one embodiment, domain name resolution server 301 can be determined based on the initiation address of access request by the access
Request analysis is to which proxy server.It is taken for example, domain name resolution server 301 can parse access request to first agent
Business device, wherein the initiation address of the access request falls in region locating for first agent's server.
Proxy server 321 for example receives the access request by monitoring 80 ports.In one example, proxy server
321 can determine the server cluster acted on behalf of access request in preferred region based on the configuration information of itself.It can in configuration information
To be stored with preferred region, so-called first choice region refers to that proxy server 321 is preferentially acted on behalf of access request to the first choice region
Server cluster.The sorted lists of other regions sorted by priority can also be stored in configuration information.
As an example, the preferred region in the configuration information of lower proxy server of normal condition is the proxy server
Region locating for itself.Such as proxy server 321, preferred region is region 1, for proxy server 322
For, preferred region is region 2.
In examples as shown in figure 3, proxy server 321 can be acted on behalf of access request to region based on own configuration information
Server cluster 331 in 1.
Proxy server 321 can be acted on behalf of access request to the server cluster in preferred region based on load balancing
The server in formal publisher server group such as server group 3311 in server cluster 331 i.e. in region 1.
Common load balancing may include repeating query equilibrium, weight repeating query equilibrium, Stochastic Equilibrium, response speed equilibrium,
Minimum connection number is balanced, processing capacity is balanced, DNS responds equilibrium etc..
Such as proxy server 321 can be acted on behalf of access request into server cluster 331 just based on load balancing
Server A in formula publisher server group 3311, if server A response abnormality, can be again based on load balancing will be visited
Other servers of request agency into the server group 3311 are asked, if response or exception, are acted on behalf of again to the server
Next server in group 3311 repeats this operation until access request obtains normal response.
In extreme circumstances, if the Servers-all in the formal publisher server group 3311 of server cluster 331 not
Energy normal response, then proxy server 321 can be acted on behalf of access request to next region based on configuration information, such as with confidence
Priority is only second to the formal publisher server group in the server cluster in next region of preferred region in breath.As showing
Example, such as proxy server 321 can act on behalf of access request to the formal issuing service in the server cluster 332 in region 2
Device group.If formal publisher server group at this time in server cluster 332 is server group 3321, by access request act on behalf of to
Otherwise server group 3321 is acted on behalf of to server group 3322.
In more extreme cases, if the formal publisher server group of the server cluster in all regions respond it is different
Often, then proxy server 321 can be acted on behalf of access request again to the pre- issuing service of the server cluster in preferred region
Pre- publisher server group 3312 in device group, such as the server cluster 331 of region 1.
If pre- publisher server group 3312 in the server cluster 331 of the region 1 also can not normal response, can will visit
It asks in request agency to next region, such as priority is only second to the server in next region of preferred region in configuration information

Server cluster in the configuration information of server in preferred region.
Further, first agent's server can be acted on behalf of access request to the first server based on load balancing
The server in formal publisher server group in cluster.Common load balancing may include repeating query equilibrium, weight repeating query
Equilibrium, Stochastic Equilibrium, response speed is balanced, minimum connection number is balanced, processing capacity is balanced, DNS responds equilibrium etc..
If the equal response abnormality of Servers-all in the formal publisher server group of first server cluster, can be by first
Access request is acted on behalf of the formal hair into the server cluster in next region based on the configuration information of itself by proxy server
Cloth server group is until access request obtains normal response.
In extreme situations, if the formal equal response abnormality of publisher server group of the server cluster in all regions,
Then access request can be acted on behalf of based on the configuration information of itself by the pre- hair into first server cluster by first agent's server
Cloth server group.
In more extreme cases, if the Servers-all in the pre- publisher server group of first server cluster responds
It is abnormal, then access request can be acted on behalf of to the clothes in above-mentioned next region based on the configuration information of itself by first agent's server
The pre- publisher server group being engaged in device cluster repeats this operation until access request obtains normal response.
It is subsequent to be detected with interval time in the case where formal publisher server group all delay machines of Servers-all cluster
Whether formal publisher server group is normal, if formal restore, so that it may switch back into formal publisher server group.
In one example, can by first agent's server parse access request main part to obtain User ID, with
In the mark of load balancing.For example, first agent's server can be based on the request lattice about access request being locally stored
Formula executes parsing to the main part of access request.
