[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing the embodiments in one embodiment and are not intended to limit this application.
[0022] It should be noted that the terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and drawings of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way.
[0023] It should also be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchanged with each other, and some steps can also be deleted. Some embodiments will be described below in conjunction with the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.
[0024] Remote Procedure Call (RPC) refers to a process calling the function of another process. Unlike function calls within a process, there is strong isolation between multiple processes. In particular, for processes located on different hosts, method parameters cannot be passed through shared memory. The current common way to pass parameters is to communicate over the network and pass method parameters through preset application layer protocols. The preset protocols include grpc protocol, thrift protocol, dubbo protocol, http protocol, etc.
[0025] The client (Consumer) of the existing RPC solution can obtain real-time information from the server (Provider). Generally, the Consumer will randomly call multiple Provider processes and try to ensure that the number of calls to all processes is roughly balanced to avoid overloading or idling a single process.
[0026] However, the existing RPC solution ignores the scenario of cross-computer room calls. Generally, for remote disaster recovery, the Provider's services are published in different computer rooms, so that even if a single computer room has a power outage or fire, the services in other computer rooms are still available. However, there are several problems when calling across computer rooms: the first problem is that the physical links between multiple computer rooms are long, usually need to pass through multiple layers of switches and routers, and the network latency is relatively high; the second problem is that network communication between multiple computer rooms requires paying high traffic fees to network operators.
[0027] In order to solve the above technical problems, an embodiment of the present application provides a remote procedure call method to solve the technical problems of relatively high network delay and high traffic costs caused by cross-computer room calls.
[0028] refer to Figure 1 As shown, it is a schematic diagram of the system architecture of the remote procedure call method provided in the embodiment of the present application. The system architecture includes a client 20, a server 30 and a registration center 40. The client 20 can be connected to the server 30 and the registration center 40 through a network (not shown in the figure). The network can be a wired communication network or a wireless communication network.
[0029] The client 20 can be various electronic devices, including but not limited to mobile phones, laptop computers, digital broadcast receivers, PDAs (personal digital assistants), PADs (tablet computers), PMPs (portable multimedia players), vehicle-mounted terminals (such as vehicle-mounted navigation terminals), and other mobile terminals, as well as digital TVs, desktop computers, and other fixed terminals.
[0030] The server 30 may be a server that provides services. For example, the server 30 may be a remote service execution server that executes a corresponding instance of the service requested by the client 20. The server 30 may execute a corresponding instance of the service requested by the client 20, obtain a call result, and feed the call result back to the client.
[0031] In some embodiments of the present application, the registration center 40 may be a single server or a server cluster. In other embodiments of the present application, the registration center 40 may be a nacos console.
[0032] It should be noted that Figure 1The number of clients, networks, servers, and registries in the example is only illustrative. Any number of clients, networks, servers, and registries may be used as required. Figure 2 FIG. 1 is a schematic diagram of a system architecture of a remote procedure call method provided by another embodiment of the present application. The system architecture includes two clients and three servers.
[0033] refer to Figure 3 As shown, it is a flowchart of the remote procedure call method provided by the embodiment of the present application. The method is applied to the client (such as Figure 1 According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.
[0034] Step S301, obtaining information of the client and the server, wherein the information includes the IP address.
[0035] In some embodiments of the present application, the server sends the information of the server to the registration center when it is powered on. The information of the server includes metadata of the service. The metadata of the service includes, but is not limited to, the address, port and service type of the server, where the address includes the IP address. The service type may include order services and user function services. For example, when powered on, the server sends a first heartbeat packet to the registration center at intervals of a first preset period (e.g., 5s), and the first heartbeat packet includes the address, port and service type of the server. The registration center receives and records the first heartbeat packet sent by the server. If the registration center does not receive the first heartbeat packet within a first preset time period (e.g., 20s), the service of the server is deregistered.
[0036] In some embodiments of the present application, when the client is powered on, the client sends the information of the client to the registration center. The information of the client includes, but is not limited to, the address and port of the client. In some embodiments of the present application, when the client is powered on, the client sends a second heartbeat packet to the registration center at intervals of a second preset period, and the second heartbeat packet includes the address and port of the client. The registration center receives and records the second heartbeat packet sent by the client.
[0037] In some embodiments of the present application, the client obtains information of all clients and servers from the registration center, thereby obtaining the IP address and port of each client.
[0038] Step S302, obtaining the network segment information of the computer room, setting the computer room mark of the client according to the network segment information of the computer room and the IP address of the client, and setting the computer room mark of the server according to the network segment information of the computer room and the IP address of the server.
[0039] In some embodiments of the present application, the client obtains the network segment information of the computer room from the registration center. Each network segment information of the computer room corresponds to a computer room. For example, refer to Figure 2 As shown in the figure, the network segment information of the computer room A is 10.86.0.0 / 16, the network segment information of the computer room B is 10.87.0.0 / 16, and the network segment information of the computer room C is 10.88.0.0 / 16. The network segment information of the computer room is 10.86.0.0 / 16, which means that the network segment information of the computer room includes all IP addresses from 10.86.0.0 to 10.86.255.255. The network segment information of the computer room is 10.87.0.0 / 16, which means that the network segment information of the computer room includes all IP addresses from 10.87.0.0 to 10.87.255.255. The network segment information of the computer room is 10.88.0.0 / 16, which means that the network segment information of the computer room includes all IP addresses from 10.88.0.0 to 10.88.255.255.
[0040] In some embodiments of the present application, setting the client's computer room tag according to the computer room network segment information and the client's IP address includes: determining the computer room network segment information to which the client's IP address belongs as the first target network segment information according to the computer room network segment information and the client's IP address; and setting the client's computer room tag to the computer room corresponding to the first target network segment information. For example, if the client's IP address is 10.87.20.100, then determine that the first target network segment information corresponding to the client of 10.87.20.100 is 10.87.0.0 / 16, and set the client's computer room tag to the computer room corresponding to 10.87.0.0 / 16, that is, computer room B.
[0041] In some embodiments of the present application, the server's computer room tag is set according to the computer room network segment information and the server's IP address: the computer room network segment information to which the server's IP address belongs is determined as the second target network segment information according to the computer room network segment information and the server's IP address; the server's computer room tag is set to the computer room corresponding to the second target network segment information. For example, if the server's IP address is 10.86.20.55, the second target network segment information corresponding to the server with an IP address of 10.86.20.55 is determined to be 10.86.0.0 / 16, and the server's computer room tag is set to the computer room corresponding to 10.86.0.0 / 16, that is, computer room A.
[0042] Step S303, respond to the remote procedure call request, select the first target server according to the computer room mark of the client and the computer room mark of the server, establish a communication connection with the first target server, and send the remote procedure call request to the first target server, so that the first target server executes the remote procedure call request, wherein the computer room mark of the first server is the same as the computer room mark of the client.
[0043] In some embodiments of the present application, after power-on, the client and the first target server may establish a communication connection through the Transmission Control Protocol (TCP). For example, the client may establish a communication connection with the transport layer of the first target server through the TCP protocol on the transport layer of the client.
[0044] In some embodiments of the present application, a first connection pool and a second connection pool are set in the client. The first connection pool records the first connection information between the client and the server, and the first connection information includes the computer room mark and IP address of the client, the computer room mark and IP address of the server, and the connection status of the client and the server at the transport layer, wherein any server in the first connection pool that establishes a connection relationship with the client has the same computer room mark as the corresponding client. In some embodiments of the present application, the connection status between the client and the server includes an available connection status and an unavailable connection status.
[0045] In some embodiments of the present application, an application or process of a client may trigger a remote procedure call request. The client responds to the remote procedure call request and selects a server having the same server room mark as the first target server from the first connection pool according to the server room mark of the client. The client determines the connection status between the client and the first target server. If the connection status between the client and the first target server is an available connection status, the client establishes a communication connection with the application layer of the first target server at the application layer.
[0046] If the connection status between the client and the first target server is unavailable, a server with a different server room mark from the client is selected as the second target server according to the client's server room mark, and a communication connection is established on the client's application layer with the application layer of the second target server.
[0047] In some embodiments of the present application, the client sets a second connection pool. The second connection pool records the second connection information between the client and the server, and the second connection information includes the computer room mark and IP address of the client, the computer room mark and IP address of the server, and the connection status of the client and the server at the transport layer, wherein the computer room mark of any client in the second connection pool and the server with which the client establishes a connection relationship is different. If the connection status between the client and the first target server is an unavailable connection state, the client selects a server with a different computer room mark from the second connection pool as the second target server according to the computer room mark of the client, and establishes a communication connection with the application layer of the second target server at the application layer of the client.
[0048] In some embodiments of the present application, the size of the first connection pool can be determined according to the number of first target IP addresses and the number of first processes. The number of first target IP addresses represents the number of servers with the same computer room identifier as the client, and the number of first processes represents the number of processes in each server for parallel processing of remote procedure call requests. In some embodiments of the present application, the size of the first connection pool can be the product of the number of first target IP addresses and the number of first processes.
[0049] In some embodiments of the present application, the size of the second connection pool can be determined according to the number of second target IP addresses and the number of second processes. The number of second target IP addresses indicates the number of servers with the same computer room identifier as the client, and the number of second processes indicates the number of processes in each server for parallel processing of remote procedure call requests. In some embodiments of the present application, the size of the second connection pool can be the product of the number of first target IP addresses and the number of first processes.
[0050] In some embodiments of the present application, when the first target server receives a remote procedure call request sent by the client, it executes the remote procedure call request and sends a processing result of the remote procedure call request to the client.
[0051] In some embodiments of the present application, after the client sends the remote procedure call request to the first target server, the method further includes: if it is detected that the client is disconnected from the first target server or no reply information sent by the first target server is received within a preset time period, re-establishing the connection with the first target server; recording the number of times the client is disconnected from the first target server; when the number of disconnections reaches a preset number, setting the connection state between the client and the first target server to an unavailable connection state. In some embodiments of the present application, setting the connection state between the client and the first target server to an unavailable connection state means setting the connection state of all processes on the first target server that are connected to the client to an unavailable connection state. In an embodiment of the present application, when the number of disconnections reaches a preset number, the connection state between the client and the first target server is set to an unavailable connection state, and when the connection process between the client and the server is re-established, the first target server can be selected again to connect to the client, resulting in consumption of computing resources.
[0052] In some embodiments of the present application, after the connection state between the client and the first target server is set to an unavailable connection state, the method further includes: detecting whether the client and the first target server can be successfully connected at every preset period, and if it is determined that the client and the first target server can be successfully connected, setting the connection state between the client and the first target server to an available connection state. In the embodiment of the present application, the preset period can be set as needed, for example, the preset period can be set to 30s.
[0053] In an embodiment of the present application, it is detected at preset intervals whether the client and the first target server can be successfully connected. If it is determined that the client and the first target server can be successfully connected, the connection status between the client and the first target server is set to an available connection status. In this way, the connection between the client and the first target server can be restored, thereby increasing the service resources of the RPC.
[0054] In the present application, the client can set the client's computer room mark according to the computer room network segment information and the client's IP address, set the server's computer room mark according to the computer room network segment information and the server's IP address, and respond to the remote procedure call request according to the client's computer room mark and the server's computer room mark, select the first target server, establish a communication connection with the first target server, and send the remote procedure call request to the first target server, so that the first target server executes the remote procedure call request. In this way, the client can give priority to remote procedure calls to the server in the same computer room, thereby solving the technical problems of relatively high network delays and high traffic costs caused by cross-computer room calls.
