It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

An execution main body of the cross-node request retry method of the star network architecture provided by the embodiment of the present disclosure may be an electronic device under any star network architecture, for example, the execution main body may be a terminal device or a server, where the terminal device may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, an in-vehicle device, a wearable device, and the like. In some possible implementations, the cross-node request retry method of the star network architecture may be implemented by a processor invoking computer-readable instructions stored in a memory.

Fig. 1 is a flowchart illustrating a cross-node request retry method of a star network architecture according to an embodiment of the present disclosure, where the cross-node request retry method of the star network architecture includes, as illustrated in fig. 1:

s10: sending a remote procedure call request to a target node;

s20: determining a proxy node from a star network architecture in response to the remote procedure call request failing;

s30: forwarding, by the proxy node, the remote procedure call request to the target node.

As described in the foregoing embodiment, the cross-node request retry method according to the embodiment of the present disclosure may be applied to a star network structure, and fig. 2 illustrates a schematic structural diagram of a star network structure according to the embodiment of the present disclosure, where the star network structure may include five node devices A, B, C, D and E, where the nodes may communicate with each other, and each node may be a server or may also be another type of electronic device.

As shown in FIG. 2, node A may be acting as a source node for performing remote procedure calls to target node C, i.e., a remote procedure call request (RPC request) may be sent to target node C. In some possible embodiments, the source node a may request the node C to perform an operation or other processing operation according to a request of a client connected thereto or according to a data processing procedure to be performed by the source node a, at this time, an RPC request may be sent to the target node C, where the RPC request may report an address of the source node a, an address of the target node C, and may further include information such as an operation identifier (e.g., a function name, an operation name, etc.) performed by the called target node C, and a relevant numerical parameter.

In some possible embodiments, if the target node C can receive the RPC request sent by the source node a, the corresponding processing operation may be correspondingly performed, and the returned response information is sent to the source node a. The response information may include a processing result of the RPC request, or may also include information of successful execution, which may be determined according to different processing operations, and this disclosure does not specifically limit this.

In other embodiments, there may be a case of device failure or network failure, which results in that the RPC request of the source node cannot be successfully sent to the target node, or the target node cannot successfully execute corresponding processing to return response information to the source node, which results in a case of request failure. At the moment, the agent node can be selected from the star network architecture, the RPC request is forwarded, and the success rate of the RPC is improved.

The mode for determining the RPC request failure may include at least one of the following modes:

A) determining that the remote procedure call request fails when response information corresponding to the procedure call request is not received within a preset time after the procedure call request is sent to the target node;

in some possible embodiments, the timing may be started after the RPC request is sent, and if the response information for the RPC request returned from the target node is not received within a preset time, it may be determined that the RPC request fails. The preset time may be a preset value, for example, 5 seconds, or may be another time threshold, which is not specifically limited in this disclosure.

B) Determining that the remote procedure call request fails when a network failure with the target node is detected;

in some possible embodiments, the current network status may be detected, and if a network status failure is detected, such as a failure to access the DNS server, or a power failure of the network interface of the source node device is detected, the network failure may be determined, and the RPC request may be determined to have failed.

Based on the above configuration, it can be determined that the RPC request fails, and at this time, the RPC request can be forwarded through the proxy node.

Fig. 3 shows a flowchart of step S20 in a cross-node request retry method in a star network architecture according to an embodiment of the present disclosure, wherein the determining a proxy node from the star network architecture in response to the remote procedure call request failure includes:

s21: acquiring response time of each node in a star network architecture aiming at a source node, wherein the source node is a node which needs to send a process calling request to a target node;

s22: and determining the node with the shortest response time as the proxy node.

In some possible embodiments, the proxy node may be determined according to a response time of each node in the star network architecture to the source node. In the history process of the operation of the star network architecture, historical data of response time among nodes can be stored. For example, for the source node a, it may start timing when the source node a sends the first request to other nodes, and determine the time when the response information of the first request is received, and use the time as the history data of the response time. The above history data is stored in the node device to be read and recalled. In addition, the first request may be a request for performing an arbitrary operation. The historical data of the response time between any two nodes can be obtained through the method.

The disclosed embodiments may determine the proxy node using an average of historical data of response times between the source node and other nodes. The average value of the response time of each node and the source node may be determined as the response time of each node for the source node, for example, the average value of the historical data of the response time of the node B for the source node a may be used as the response time of the node B for the node a, so that the response time between each node and the source node may be determined. The embodiment of the present disclosure may determine a node having the smallest average value of the history data of the response time with the source node as the proxy node. With this configuration, it is also possible to reduce the request time in the case of providing a success rate of RPC requests.

Further, under the condition of the determined proxy node, the RPC request may be forwarded by the proxy node, and the source node may send forwarding information to the proxy node, where the forwarding information includes the RPC request to be transmitted, an address of the source node and an address of the proxy node, so that the proxy node may be used to complete the forwarding of the RPC request. In the process of forwarding the RPC request, if the forwarding fails, the proxy node of the embodiment of the present disclosure may feed back the failure result to the source node. The manner of determining the forwarding failure is the same as the manner of determining the RPC request failure, and is not described herein again.

In the event that the source node determines that proxy node forwarding fails, a new proxy node may be reselected. The new proxy nodes may be determined according to the order of the average of the obtained historical data of the response time from small to large, and the node with the smallest response time except the failed proxy node is selected as the new proxy node. According to the method, the success rate of the RPC request can be further improved.

In addition, in the embodiment of the present disclosure, when the proxy node fails to forward the RPC request, the proxy node of the proxy node may also be selected according to the embodiment of the present disclosure, that is, the proxy node may be used as a source node, the proxy node of the source node is selected, and the RPC request is forwarded.

The retry procedure of the disclosed embodiment is illustrated below with reference to fig. 2 as an example. The source node A is used for sending an RPC request to the target node C, and under the condition that the RPC request is judged to fail, the proxy node B is selected from the star network architecture to forward the RPC request, wherein the adjacent node of the source node can be determined to be the proxy node through response time, and the proxy node B is selected to forward the RPC request. The source node A sends a forwarding request to the node B, and the proxy node B forwards the RPC request to the target node C according to the request to complete the forwarding of the RPC request.

In addition, each electronic device in the star network architecture of the embodiment of the present disclosure may be configured to execute the method, and the electronic device may determine whether to start the proxy forwarding function according to the received configuration selection information, and may receive and send an RPC request when the proxy forwarding function is started. The embodiment of the present disclosure may automatically start the proxy forwarding function when the electronic device is started, or may also receive configuration information transmitted from other devices (e.g., a control device) to perform switching between starting and stopping of the proxy forwarding function. In addition, in the embodiment of the present disclosure, each electronic device in the star network architecture may share the current state of the proxy forwarding function with each electronic device in the network when the proxy forwarding function changes, so that the electronic device in the network may obtain and store the turn-tables of the proxy forwarding functions of other electronic devices in real time, and when selecting a proxy node, may select a proxy node from the nodes that start the proxy forwarding function.

In summary, in the embodiment of the present disclosure, when each node of the star network architecture executes Remote Procedure Call (RPC) of a target node, when a request fails, other nodes in the star network architecture may serve as proxy nodes to help forward a remote call request, so that a success rate of RPC in the star network may be improved.
