Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
First, some terms in the present application will be explained in order to be understood by those skilled in the art.
Client side: the message sending and receiving, the sending and receiving attribute of the client is pub, which means that the client is a message sending process, and the sending and receiving attribute of the client is sub, which means that the client is a message receiving process.
Proxy server: a messaging proxy server.
Configuration center: the address of the proxy server to which the client can connect is stored.
The registry: the data with which the proxy server is registered is stored.
In the prior art, the relative balance of the number of clients proxied by the proxy server is ensured based on a random algorithm. However, for a certain proxy server, such as proxy server a, only has the information of its own proxy status, but proxy server a does not have the information of the proxy status of other proxy services, so that the messages to be sent and received are easily concentrated on the same proxy server, and the proxy server is greatly affected when it fails.
Based on this, the embodiment of the present invention provides a method for messaging, which may be applied to a system architecture shown in fig. 1, where the system architecture includes a configuration center 100, a client 200, a proxy server 300, a registry 400, and a message queue server 500.
Wherein the proxy server 300 determines group information to which the client 200 belongs and acquires proxy status of each proxy server of the client having the same group information proxied from the registry 100. The proxy server 300 determines a proxy server of the proxy client based on the proxy status of each proxy server.
In one possible implementation, proxy server 300 receives a proxy recommendation request sent by client 200.
The proxy recommendation request includes group information indicating to which the client 200 belongs.
In another possible implementation, the proxy server 300 determines the group information to which the client belongs from the transceiving messages of the client that has been currently proxied.
The registry 400 receives proxy conditions of the proxy servers 300 and stores proxy data while providing an interface for querying the proxy conditions of each proxy server for the proxy server 300.
The message queue server 500 is used for storing messages sent and received by the client 200.
It should be noted that fig. 1 is only an example of a system architecture according to an embodiment of the present application, and the present application is not limited thereto in particular.
Based on the system architecture illustrated above, fig. 2 is a flow diagram corresponding to a method for messaging according to an embodiment of the present invention, as shown in fig. 2, where the method includes:
In step 201, the first proxy server determines group information to which the first client belongs.
It should be noted that, the first client is any one of the clients; each client receives and transmits information through each proxy server; wherein the group information is determined at least according to the subsystem to which the client belongs.
In step 202, the first proxy server obtains the proxy status of the second proxy server from the registry.
It should be noted that, the second proxy server includes the second client having the group information in the clients that have been currently proxied, and the proxy status is used to indicate the status of the second client.
In step 203, the first proxy server determines a third proxy server for proxy of the first client according to the proxy status of the second proxy server.
In the embodiment of the application, each proxy server reports the proxy condition of the proxy server to the registration center, the proxy server is uniformly stored by the registration center, and the registration center provides an interface of the proxy condition of each proxy server for the proxy server to inquire.
For example, the proxy server starts a timing task after starting, and reports the proxy status of the proxy server to the registration center at regular time.
Specifically, the report content includes: the cluster name to which the proxy server belongs, the proxy server name, the number of clients to which each group of the proxy belongs as the transmission/reception attribute, the number of clients to which each group of the proxy belongs as the reception attribute, and the like.
The embodiment of the application groups the clients before step 201.
Specifically, the group information is determined at least according to the subsystem to which the client belongs.
In one possible implementation, clients belonging to the same subsystem and belonging to the same data center are determined to be the same group.
For example, the group information is determined based on the subsystem to which the client belongs and the data center (DATA CENTER Node, DCN).
Specifically, as shown in fig. 3: the subsystem A and the subsystem B are respectively provided with 6 clients, wherein the clients of the subsystem A are respectively a client A1, a client A2, a client A3, a client A4, a client A5 and a client A6, and the clients of the subsystem A are respectively a client B1, a client B2, a client B3, a client B4, a client B5 and a client B6.
As can be seen from the figure, DCN1 and DCN2 also respectively include 6 clients in the dashed boxes, where the clients of DCN1 are respectively client A1, client A2, client A3, client B1, client B2, and client B3. The clients of DCN2 are client A4, client A5, client A6, client B4, client B5, and client B6, respectively.
Further, the group determined according to the subsystem a and DCN1 includes a client A1, a client A2, and a client A3; the group determined according to the subsystem A and the DCN2 comprises a client A4, a client A5 and a client A6; the group determined according to the subsystem B and the DCN1 comprises a client B1, a client B2 and a client B3; the group determined by subsystem B and DCN2 includes client B4, client B5, and client B6.
It should be noted that, the clients may be grouped according to the subsystem number, which is not specifically limited in the embodiment of the present application.
Further, the address list of the proxy server connected with the client and the address of the registry connected with the proxy server are configured in the configuration center in advance.
In one possible way, as shown in table one:
Key Value Description
proxyServerAddr Ip1:port1#IDC1；Ip2:port2#IDC2 Address of proxy server
proxyRegistryAddr Ip1:port1；Ip2:port2；Ip3:port3 Address of registry
The IDC1 is a machine room identifier of the machine room (INTERNET DATA CENTER, IDC) where Ip1 is located.
In one possible implementation manner, the first proxy server receives a proxy recommendation request sent by the first client.
It should be noted that, the agent recommendation request includes group information for indicating that the first client belongs to; the proxy recommendation request is sent by the first client before sending and receiving the message.
Specifically, before the first proxy server receives the proxy recommendation request sent by the first client, the first client selects the first proxy server to be queried so that the queried first proxy server determines the third proxy server.
Further, the first client obtains an address list of the connectable first proxy server from the configuration center, and selects the proxy server for query according to the IDC where the first client is located.
For example, the IDC where the first client is located is IDC1, and the proxy server belonging to IDC1 is preferentially found from the list returned by the configuration center to query.
In the embodiment of the application, when the IDC where the first client is located does not exist, the proxy server of other IDCs is randomly selected for inquiring.
In the embodiment of the present application, after the first proxy server receives the proxy recommendation request sent by the first client, in step 202, the first proxy server queries the registry for the proxy status of each proxy server that proxies the client with the same set of information.
Further, the query results are classified into a proxy condition on a proxy server of the same IDC as the first client, and a proxy condition on a proxy server of a different IDC than the first client.
Specifically, the first proxy server determines the third proxy server according to the number of second clients with the same transceiving attribute as the first clients on the second proxy server.
In the embodiment of the application, the proxy server with the least number of the group of the clients is selected to be returned from the proxy servers of the same IDC as the clients preferentially, and when the proxy server of the same IDC as the clients is not available, the proxy server with the least number of the group of the clients is selected to be returned from the proxy servers of other IDCs.
For example, the clients included in the group of clients determined by the subsystem a and the DCN1 are the client A1, the client A2, the client A3, the client A4, the client A5, and the client A6, respectively, that is, the group numbers corresponding to the group information of the 6 clients are all a-DCN1. And the receiving and transmitting attributes of the 6 clients are all sending messages. IDC1 includes three proxy servers, namely proxy server 1, proxy server 2 and proxy server 3. Specifically, the client A1 is connected to the proxy server 1, the client A2 is connected to the client A3 and the proxy server 2, and the client A4 is connected to the client A5 and the proxy server 3.
Further, when the newly added client A6 from IDC1 is to be added, the proxy server obtains the proxy status of each proxy server having the same set of information as the proxy server from the registry, and it can be seen that the proxy server with the smallest number of the set of clients of proxy a-DCN1 among the proxy servers of IDC1, which are the same as the client, is the proxy server 1, and returns the proxy server 1 as the target server.
For another example, the clients included in the group of clients determined by the subsystem B and the DCN2 are the client B1, the client B2, the client B3, the client B4, the client B5, and the client B6, respectively, that is, the group numbers corresponding to the group information of the 6 clients are all B-DCN2. And the receiving and transmitting properties of the 6 clients are all received messages. IDC3 includes three proxy servers, namely proxy server 4, proxy service 5, and proxy server 6. Specifically, the client B1 is connected to the proxy server 4, the client B2 is connected to the client B3 and the proxy server 5, and the client B4, the client B5, and the client B6 are connected to the proxy server 6.
Further, when the newly added client B7 from IDC2 is to be added, the proxy server obtains the proxy status of each proxy server having the same set of information as the proxy server from the registry, and it can be seen that the proxy server of IDC2 is the proxy server of the set of clients that does not have proxy B-DCN2 among the proxy servers of IDC2, however, the proxy server of IDC3 is the proxy server 4 with the least number of proxy B-DCN2 among the proxy servers of IDC3, and returns the proxy server 4 as the target server.
According to the scheme, the client establishes connection with the recommended proxy server according to the recommended result returned by the proxy server, so that the clients in the same group are relatively uniformly distributed on different proxy servers in the establishing stage.
The above describes the establishment of a connection phase with a relatively balanced distribution of clients having the same set of information to different proxy servers, and the following describes the specific procedure of a relatively balanced distribution of clients having the same set of information to different proxy servers during the run phase.
In the real-time example of the application, when the first proxy server runs, the first proxy server determines the group information of the first client from the received and transmitted messages of the first client which is currently proxied.
Specifically, the first proxy server determines the number of fourth proxy servers with the same machine room identification as the first proxy server in the second proxy server and the number of third clients with the same receiving and transmitting properties as the first client in the second clients proxied by the fourth proxy server;
the first proxy server determines a proxy threshold according to the number of the fourth proxy servers and the number of the third clients;
The first proxy server determines the number of the fourth clients which are provided with group information and have the same transceiving attribute with the first clients and are of the self proxy;
and the first proxy server determines the proxy server needing to be changed for the first client and the number of the first client needing to be changed according to the proxy threshold and the number of the fourth client.
The machine room identifies the IDC as described above.
In a possible implementation manner, when avg > =2 and currentnum-avg > avg/2, redirecting avg/2 clients with the same transceiving attribute, which are proxied by the proxy server, so as to realize the quantity modification of the first client;
when avg <2, currentnum-avg >1, redirecting 1 client with the same receiving and transmitting attribute, which is proxied by the proxy server; wherein, avg is a proxy threshold, currentNum is the number of clients with the same transceiving attribute that are proxied by the current proxy server;
Otherwise, it is determined that the proxy server is not redirected.
Note that, avg is a proxy threshold, currentNum is the number of clients with the same transceiving attribute that are proxied by the current proxy server.
For example, proxyM is IDC1, proxyM obtains proxy conditions on all proxy of IDC 1. proxyM for client X1, clients X2, proxyN for client X3, clients X4, proxyP for client X5, client X6 and client X7.
The clients X1, X2, X3, X4, X5, X6, and X7 have the same group information. IDC1 also contains a proxy server proxyQ, proxyS, proxyT, proxyR.
Further, the total number of clients (total) of the set of proxy servers for IDC1 is 7, the number of proxy for IDC1 is 7 (proxyNum), and the number of clients (currentNum) of the set of proxyP agents is 3 for proxyP, calculated from the proxy conditions of proxy servers proxyM, proxyN and proxyP. A determination proxyP is made as to whether it is necessary to redirect some of the clients by comparing proxyP the number of clients to the number of instances that each proxy should split on average.
It should be noted that, the specific formula of the number of examples to be divided into each proxy is: avg=total/proxyNum.
In the above example, avg value is 1 and currentnum is 3, that is, 1 of the group of clients proxied by proxyP are redirected if avg <2 and currentNum-avg >1 are satisfied.
From the foregoing, it can be seen that the number of clients that need to be changed is determined by a specific policy. In one possible implementation, the third generation server is determined to meet the balancing condition when a difference between the number of clients with group information of the third generation server agent and the number of clients with group information of the second generation server agent is less than a set threshold.
According to the scheme, when one proxy server fails, the clients with the same group of information are distributed on different proxy servers relatively uniformly no matter whether the receiving and transmitting attributes of the clients are transmitted or received, so that the influence of the proxy server failure on the service is reduced.
