[0002] With the rapid development of Internet technology, the application scenarios of edge computing technology are increasing, such as industrial Internet, public security and surveillance. Edge computing technology is to deploy the computing tasks required by users at the edge of the network close to the data source, and use edge resources to provide services to users, thereby reducing the amount of data uploaded to the cloud data center and alleviating network bandwidth pressure. The edge computing architecture consists of two parts, namely the cloud and the edge. The cloud is responsible for the distribution of applications and configurations, and the edge is responsible for running edge applications and managing access devices.

[0108] See also Figure 1 , Figure 1 1 is a flow chart of a method for enhancing cloud-edge communication disclosed in an embodiment of the present invention. Figure 1 The method for enhancing cloud-edge communication described above can be applied to the cloud, wherein the cloud message center can be understood as a local server or a cloud server, which is not limited in the embodiments of the present invention. Figure 1 As shown, the method for enhancing cloud-edge communication may include the following operations:

[0109] 101. Edit the cloud configuration files.

[0110] In an embodiment of the present invention, optionally, the configuration file of the cloud can be used to instruct the cloud to select a communication client to establish communication with the edge, wherein the communication client may include a QUIC client or a WebSocket client, which is not limited in the embodiment of the present invention.

[0111] 102. After the configuration file in the cloud is edited, the cloud loads the configuration file in the cloud to obtain a first loading result.

[0112] In the embodiment of the present invention, optionally, the cloud can verify the edited cloud configuration file, and after the verification is correct, it can be loaded according to the corresponding configuration file to obtain a first loading result, which is not limited in the embodiment of the present invention.

[0118] It can be seen that the method for enhancing cloud-edge communication described in the embodiment of the present invention can be applied to the cloud and the edge. The cloud can establish a message communication connection with the edge. On this basis, the cloud edits the cloud configuration file. After editing the cloud configuration file, the cloud loads the cloud configuration file to obtain a loading result. Based on the loading result, the cloud listens for the connection request from the edge. When the connection request from the edge is listened, the cloud parses the connection request to obtain a parsing result. Based on the parsing result, the cloud connects to the edge for communication. The QUIC transmission protocol can be introduced for the cloud and edge that support the WebSocket transmission protocol, which can reduce the occurrence of communication interruptions and the time spent on establishing a connection, thereby improving communication efficiency.

[0119] Embodiment 2

[0120] See also Figure 2 , Figure 2 is a flow chart of another method for enhancing cloud-edge communication disclosed in an embodiment of the present invention. Figure 2 The method for enhancing cloud-edge communication described above can be applied to a cloud message center, where the cloud message center can be understood as a local server or a cloud server, which is not limited in the embodiments of the present invention. Figure 2 As shown, the method for enhancing cloud-edge communication may include the following operations:

[0121] 201. Edit the cloud configuration files in the cloud.

[0125] 203. The cloud loads the configuration file of the cloud based on the registration result to obtain a first loading result.

[0126] 204. The cloud monitors the connection request from the edge based on the first loading result.

[0127] 205. After monitoring the connection request from the edge, the cloud parses the connection request and obtains the parsing result.

[0128] 206. The cloud connects to the edge for communication based on the analysis results.

[0129] In the embodiment of the present invention, the specific technical details and technical terminology of step 201 and step 203 to step 206 can refer to the description of step 101 to step 105 in the first embodiment, and will not be repeated here.

The cloud can establish a message communication connection with the edge. On this basis, the cloud edits the configuration file of the cloud. After editing the configuration file of the cloud, the cloud loads the configuration file of the cloud to obtain a loading result. Based on the loading result, the cloud monitors the connection request of the edge. When the connection request of the edge is monitored, the cloud parses the connection request to obtain a parsing result. Based on the parsing result, the cloud connects to the edge to communicate. The QUIC transmission protocol can be introduced for the cloud and edge that support the WebSocket transmission protocol, which can reduce the occurrence of communication interruptions and reduce the time spent on establishing a connection, thereby improving communication efficiency. In addition, the management of the working status of the communication channel between the cloud and the edge can be achieved by registering a message processing function, thereby improving communication efficiency.

[0131] In an optional embodiment, in the above step 201, editing the cloud configuration file in the cloud may include:

[0132] The first startup file of the QUIC client and / or the second startup file of the WebSocket client are edited in the cloud. As configuration files in the cloud, the first startup file of the QUIC client and / or the second startup file of the WebSocket client can be used to instruct the QUIC client and / or the WebSocket client to enter a working state.

[0135] Among them, the cloud connects to the edge end for communication based on the analysis results, which may include:

[0136] When the state of the QUIC client is the first enabled state, the WebSocket client can be closed. At this time, the cloud can communicate with the edge through the QUIC client based on the parsing result, which is not limited in the embodiment of the present invention;

[0137] When the state of the WebSocket client is the second enabled state, the QUIC client can be closed. At this time, the cloud can communicate with the edge through the WebSocket client based on the parsing result, which is not limited in the embodiment of the present invention.

[0138] It can be seen that this optional embodiment can introduce the QUIC communication protocol for the cloud and edge that support the WebSocket communication protocol. The cloud and edge can choose to use either the WebSocket communication protocol or the QUIC communication protocol for communication, which increases the choice of communication protocols and reduces congestion during the communication process, thereby being more conducive to completing communication tasks.

On this basis, the edge loads the configuration file of the edge to obtain a loading result. The edge initializes the channel client based on the loading result. After editing the configuration file of the cloud, the cloud loads the configuration file of the cloud to obtain a loading result. The edge reads the configuration file of the channel client and sets the node identifier of the edge. Based on the node identifier of the edge that has been set, the edge sends a connection logic request to the cloud, and after receiving feedback sent by the cloud to allow the connection to be established, the edge establishes a connection with the cloud. The QUIC transmission protocol can be introduced for the cloud and edge that support the WebSocket transmission protocol, which can reduce the occurrence of communication interruptions and the time spent on establishing a connection, thereby improving communication efficiency. In addition, encrypting the certificate of the channel client can improve the channel security of cloud-edge message transmission. According to the communication working status of the currently selected channel client, the edge end is instructed to retain the currently selected channel client or switch to one of the backup channel clients. This can realize automatic migration of connections and error correction during communication, greatly improving the efficiency of cloud-edge communication.
