Illustrative methods
Example embodiment of the present invention first proposed a kind of network request retransmission method, and Fig. 1 shows to apply and be somebody's turn to do The exemplary system architecture of method.
Refering to what is shown in Fig. 1, the system 100 may include proxy server 111,121, console 112,122, data base set Group 113,123, link-local 114,115,124,125, foreign link 116,126,117,127 and reserve link 108.Its In, proxy server 111,121 is used to receive the network request of user's transmission, corresponding console 112,122 is transferred it to, Such as can be Nginx server, Apache Server etc..Console 112,122 is for continuing network request to be forwarded to number It feeds back according to library cluster 113,123, or after transferring corresponding data from data-base cluster 113,123 to user, usually can be industry Business control centre, front-end server etc..Data-base cluster 113,123 is used to store data, the basic-level support for providing each business etc., It usually can be back-end server or database.
System 100 can be divided into multiple regions from transverse direction.In this example embodiment, region refers to storage data base set The minimal geographical unit of group, the data-base cluster in each region are deposited in same computer room.Such as the data in a city are whole It is stored in the data-base cluster in a computer room, then region can represent city, if the data storage in a city is in more In the data-base cluster of a computer room, the data-base cluster of each computer room stores the data in a district, then region can be with Representative Region County.In each region, the main distinction of console 112,122 and data-base cluster 113,123 is that console 112,122 is integrated Each business module in region, and the business that data-base cluster 113,123 is console rear end is segmented, such as console can be with Map in integrated region, call a taxi, the front end of every business module such as service for life is shown, and data-base cluster can be to these Business module provides the data of rear end respectively or application is supported, each database or server in data-base cluster are responsible for wherein A business.
Region 1 and region 2 in Fig. 1 are mutually independent geographic area.By taking region 1 as an example, proxy server 111, control Platform 112 processed can deposit in the computer room in the region where data-base cluster 113, can also deposit in other machines in the region Room, but the proxy server 111 of the same area, console 112 and data-base cluster 113 should have operational relevance.
System 100 can be divided into multiple response layers from longitudinal direction：First response layer is Agent layer, by multiple proxy servers 111,121 composition；Second response layer is control layer, is made of multiple consoles 112,122；Third response layer is data Layer, by Multiple data-base clusters 113,123 form.
Based on above description, the network request retransmission method of this example embodiment can be applied to initial in Agent layer The proxy server (111 or 121) for receiving the network request that user sends, is known as target proxy clothes in this example embodiment Business device.
It should be appreciated that region shown in FIG. 1, proxy server, console, data-base cluster quantity be only exemplary , according to actual needs, any number of region can be set, any number of proxy server can be set in each region With console, data-base cluster can be made of any number of database or server.
Fig. 2 shows a kind of flow charts of network request retransmission method of this example embodiment.Refering to what is shown in Fig. 2, should Method may comprise steps of：
S21 receives network request, and determines access region according to network request.
In this example embodiment, network request can be any form of request, such as accessing page request, data are write Enter request, data read request etc., wherein the access domain name of network request, cookie, location information etc. may include access region The relevant content in domain.Target proxy server does not carry out substantive processing to network request, only identifies access region therein Domain, to carry out subsequent forwarding.Target proxy server can be the proxy server of access region, be also possible to other regions Proxy server, by taking system 100 shown in FIG. 1 as an example, when access region is region 1, target proxy server be can be The proxy server 111 in region 1 is also possible to the proxy server 121 in region 2.
Whether S22, the connection for detecting the console of target proxy server and access region are normal.
Connection normal need meets that console is normal and connecting link is normal simultaneously, wherein there is an exception all companies of will lead to Connect exception.For example, needing console 112 and link-local 114 normal simultaneously, proxy server 111 and console 112 in Fig. 1 It could normally connect.Detection can be accomplished in several ways, such as can be with the period between target proxy server and console Property mutual transmission heartbeat message illustrate that connection is abnormal if can not receive the heartbeat message of console；Or target proxy clothes Business device can send test post to console when detecting, if can not receive feedback in the predetermined time, illustrate that connection is abnormal Etc., this example embodiment is not specially limited this.
Network request is forwarded to the console of access region when connecting normal by S23.
Network request is forwarded to the console of alternative area when connecting abnormal by S24.
Wherein, access region is different geographic areas from alternative area.By taking Fig. 1 as an example, if the access of network request Region is region 1, then network request is preferentially forwarded to the console 112 in region 1, when target proxy server and console When 112 connections are abnormal, network request can be forwarded to the console of alternative area, such as the control in region 2 can be forwarded to Platform 122, since console 122 is connect with the data-base cluster 113 in region 1 by foreign link 126, console 122 can be incited somebody to action Network request is normally forwarded to data-base cluster 113, or feeds back after 113 called data of data-base cluster to network request, That is response results identical with the console of access region may be implemented in the console of alternative area, are not influencing network request just Often processing.
In the above method, when the console of access region breaks down, it can be switched to the console of alternative area, from And the long-distance disaster of console is realized, the wind resistance for improving system is dangerous.And establish by detection proxy server with The mechanism of connection status auto-changeover control platform between console, manpower intervention is few, user's unaware, ensure that system is handled The fluency of network request.
In certain embodiments of the present invention, if target proxy server and the connection of the console of access region are different Often, it caused by order to confirm console exception or connecting link exception, can attempt to connect by other proxy servers The console.Refering to what is shown in Fig. 3, when the connection exception of target proxy server and the console of access region, network request Retransmission method can also include the following steps：
S31 obtains the connection status of at least one other proxy server and the console of access region in Agent layer.
S32 forwards network request when the connection of other above-mentioned proxy servers and the console of access region is normal To other proxy servers, make other proxy servers that network request to be forwarded to the console of access region.
S33 is executed when the connection exception of other above-mentioned proxy servers and the console of access region by network request The step of being forwarded to the console of alternative area.
It is target proxy server with proxy server 111 in Fig. 1, region 1 is illustrated for access region.When agency takes When business device 111 connect abnormal with console 112, the proxy server 121 of detection zone 2 and the connection status of console 112, such as Fruit connection is normal, illustrates that link-local 114 is abnormal, can be different by reserve link 108- proxy server 121- by network request The route of ground link 127 is forwarded to console 112；If connection is abnormal, illustrate that the abnormal probability of console 112 is larger, it can be with Network request is forwarded to console 122 by foreign link 117.
Certainly, when detecting the connection status of console of other proxy servers and access region, other agency services The quantity of device can be not limited to one, and link-local 114 and foreign link 127 may be abnormal simultaneously as shown in figure 1 for example, then can be again The proxy server of detection zone 3 and the connection status of console 112, and pass through the agency service in region 3 when connecting normal Network request is forwarded to console 112 by device.The quantity for detecting other proxy servers can be usually set in systems, such as When being set as 3, the connection status of the console of 3 other proxy servers and access region is detected, if all connection is abnormal, Then judge console exception.
It should be noted that the logic of network request forwarding is preferentially to be forwarded to the control of access region in present embodiment Platform processed, only when target proxy server all connect exception with the console with other proxy servers of detection, just by net Network requests the console for being forwarded to alternative area.
In certain embodiments of the present invention, determine that access region can be by following steps reality according to network request It is existing：Detect network request whether inclusion region handoff parameter；If do not included, by the initial request of the affiliated session of network request Region is determined as access region；If comprising the region that region handoff parameter is specified is determined as access region.
Wherein, region handoff parameter refers to the order parameter in the active handover access region for including in network request, usually It is to be generated by the active operation of user, such as user clicks the network request that region handoff options are initiated in the page, user The network request that region of search keyword is initiated, user click the network that GPS (global positioning system) orient control is initiated Request etc. can include the handoff parameter of direction specific region.
Network request is usually the single request in session, when network request does not include region handoff parameter, Ke Yiwei Hold the initial request region of session.In certain embodiments of the present invention, the initial of session can be determined by following steps Request region：According in the initial access domain name of the affiliated session of network request, initial cookie and initial positioning information at least A kind of determining initial request region.For example, client request accesses " region1.news.163.com " to establish session, or When client request establishes session, system reading area from client cookie is region1 or client request is established When session, the GPS signal or IP address (network protocol landlord) of system detection to client belong to the region region1, are ok The initial request region of session is determined as region1.
For determining the initial request region of session by cookie, region handoff parameter is not included in network request When, system can keep strategy using access region, and access region is determined as to the initial request region of session, proxy server Pseudocode can be as follows：
In network request inclusion region handoff parameter, access region preferentially can be determined according to region handoff parameter.Generation The pseudocode for managing server can be as follows：
It should be noted that the region that region handoff parameter is specified is usually different from the initial request region of session, but It can also be identical under some cases.Such as user establishes browsing news page by input domain name " region1.news.163.com " The session in face, if user initiates access by selection " region2 " option in conversation procedure The network request of " region2.news.163.com ", then initial request region is region1, the specified area of region handoff parameter Domain is region2, and the two is different zones；If user clicks positioning control in the page of " region1.news.163.com " Part is to initiate the network request of the access local news page, and system is located according to the GPS signal of user side client Region1, then the region that initial request region and region handoff parameter are specified all is region1.
In certain embodiments of the present invention, the initial request region of the affiliated session of network request and target proxy service Device region can be the same area.Agent layer contains multiple proxy servers, can by the initial request region of session To determine which proxy server sent by network request.For example, user can input special domain in Web browser Name logs in Web by the corresponding proxy server of the domain name；Or user requests access to Web, system reads cookie, will ask Seek the proxy server for being assigned to the history access region recorded in cookie；Or user requests access to Web, system according to Request is assigned to the proxy server etc. of the IP affiliated area by the IP address at family.
In addition, when connecting abnormal, the net for causing user to issue by client between client and target proxy server When network request can not reach target proxy server, system can be by dividing again in DNS (domain name system) modification domain name, Agent layer With etc. modes, network request is connected to the proxy server in other regions, service is made to remain normal.
In certain embodiments of the present invention, the console of access region may include multiple console nodes；Work as mesh When the connection status of mark proxy server and the console of access region is normal, network request is forwarded to the control of access region Platform may comprise steps of：When detecting that target proxy server connect normal with a console node, network is asked It asks to be forwarded to and connect the normal console node with target proxy server；When detecting target proxy server and at least two When a console node all connects normal, according to load-balancing algorithm, network request is forwarded to and is connected with target proxy server Connect normal console node.
Disposing multiple console nodes may be implemented High Availabitity in access region, when a console node occur it is different Often, other console nodes can be rapidly switched to；On the other hand, it is distributed at multiple console nodes by load-balancing algorithm The efficiency of console processing concurrent tasks can be improved in the task amount for managing network request.
It should be appreciated that above scheme is not limited to access region, multiple console nodes, shape can be disposed in each region At the console cluster in region, to realize console High Availabitity and the load balancing in each region.
It is similar with console, High Availabitity deployment can be carried out to proxy server.In some embodiment party of the invention In formula, target proxy server may include major heading proxy server and standby target proxy server, wherein major heading generation Server is managed to be used to send state representation information to standby target proxy server；Standby target proxy server is used for according to state table Reference is ceased when determining major heading proxy server exception, replaces major heading proxy server.Wherein, state representation information can To be the heartbeat message of periodicity sending, it is also possible to the alert message etc. of exception-triggered.In addition to target proxy server, each Proxy server in region can be carried out active and standby configuration, when master proxy server exception, be immediately switched to standby agency's clothes Business device, realizes the proxy server High Availabitity in region.
In this example embodiment, Regional Representative stores the minimal geographical unit of data-base cluster, level-one bigger than region Geographical unit can be area, area is made of several regions, such as when region is city, area can be province, and region is When district, area can be city.It in certain embodiments of the present invention, can be by access region above-mentioned in areal Adjacent area is determined as alternative area.Adjacent area can be the nearest region of geographic distance, and forwarding network is asked in areal Asking has lower cost compared to trans-regional forwarding, and forwarding can further speed up response speed between adjacent area.
Further, a main region can be set up in each area, such as can be by data volume in each area most Big region is determined as main region, or operation maintenance personnel office region in each area is determined as main region etc..At this In some embodiments of invention, when the console of detection target proxy server and whole region in area belonging to access region Connection it is all abnormal when, the main region of adjoining area can be determined as alternative area.Area belonging to usual access region occurs When regional sexual abnormality, target proxy server all can not may normally be connect with whole consoles in this area, at this time can be with Trans-regional High Availabitity is realized in trans-regional forwarding.
Example embodiment of the present invention also proposed a kind of network request response method, can be applied to network request processing The console of system, the network request processing system may include Agent layer, console and data-base cluster.With reference to above-mentioned Fig. 1 Shown, network request processing system can be the system 100 in figure, and the method for this example embodiment can be applied to console 112,122.Wherein, network request response refers to processing or feedback to network request, in this example embodiment, according to network The concrete form of request, console can choose the specific response mode of following two：Be forwarded to rear end data-base cluster or It is post-processed from data-base cluster called data.As it can be seen that the function of console and proxy server has significant difference, agency service Device is only capable of being forwarded network request and can not carrying out substantive processing, and console can both turn network request Hair can also carry out substantive processing.
Refering to what is shown in Fig. 4, the method for this example embodiment may comprise steps of：
S41, the network request of Receiving Agent layer forwarding.
S42 identifies the access region of network request.
Wherein, console can be the console of the access region, be also possible to the console in other regions, such as can be with It is the console etc. of the alternative area of access region.
Network request is forwarded to the data-base cluster of access region and/or from the data-base cluster tune of access region by S43 Access evidence simultaneously handles network request.
As shown in Figure 1, connection is formed between the console 112,122 of different zones and data-base cluster 113,123, it can be with Realize the forwarding or called data post-processing in step S42.Forwarding usually occurs when network request is data write request, or When person's network request needs to interact with the data-base cluster of console rear end or server etc.；Called data post-processing usually occurs Network request be reading data or searching request when, such as network request be searching request when, console can be according to search Keyword related data is searched in data-base cluster, specific UI (user interface) form is converted into after transferring and is gone forward side by side Row processing.
In certain embodiments of the present invention, console can also independent of data-base cluster and to network request into Row separate responses.The network request response method can also include：
Before the access region of identification network request, the corresponding type of interaction of network request is judged.
If network request corresponds to console type of interaction, separate responses network request.
Wherein, the network request of console type of interaction is the above-mentioned net that can be responded independent of data-base cluster Network request, such as when request browsing pages, the page may be cached in console, then console can be with the independent process request. On the other side is the network request of database type of interaction.
If network request corresponding to database type of interaction, executes the step of access region for identifying network request S42 and subsequent step S43.
Refering to what is shown in Fig. 5, following three types can be classified as according to the area attribute of data-base cluster：
Local service, usually local proprietary business or data, the local service Dynamic data exchange in each region are disposed, no It can not be shared between region, to mitigate data backup amount.
Regional sex service, usually area in share business or data, area in each region regional sex service number According to that can share completely, it can also all be stored into the data-base cluster of regional main region, and carry out certain backup, may be used also It is stored respectively with the data-base cluster by each region, and in regional main region centralized backup；Situation as shown in Figure 5, region 1 For regional main region, the provincialism service data in this area is all stored in the data-base cluster in region 1, and in other regions It is backed up.
Global service, entire business towards global scope in share business or data, can with as shown in figure 5, Data interchange is formed between all regions, can also be formed and be backed up in the main region in each area.
Based on data-base cluster framework shown in fig. 5, in certain embodiments of the present invention, refering to what is shown in Fig. 6, by net Network request is forwarded to the data-base cluster of access region and/or from the data-base cluster called data of access region and handles network Request may comprise steps of：
S61 judges the corresponding service type of network request.
