A typical scenario is where an edge computing gateway is located behind a NAT device; a typical example of an application of such a scenario is an application system of a cloud environment.

Because the gateway is located behind the NAT, the application cannot directly access the gateway, the scene requires the gateway to actively establish connection with the application, requires the transfer of messages between the gateway and the application through the Mqtt connection, and the application needs to provide an Mqtt Server, and actively establishes connection with the Mqtt Server after the gateway is started according to the configured Mqtt Server address.

1. and constructing an Mqtt server on the public network, realizing a protocol conversion module on the edge computing gateway, actively establishing connection between the edge computing gateway and the Mqtt server, and acquiring access authorization of the public network Mqtt server by the application.

Specifically, starting an Mqtt Server in an application, firstly, requiring AppId and AppSecret corresponding to the application in a cloud platform (an administrator operation with cloud platform management authority); authorizing the service of the corresponding gateway to the corresponding application in the cloud platform; the gateway connects to the Mqtt Server of the application through the Mqtt Client.

2. And initiating a data message request based on the Mqtt protocol to the Mqtt Server, designating the data packet to the edge computing gateway through the topic of the MQT, wherein the data message carries related information of HTTP (hyper text transfer protocol) such as URL (uniform resource locator), protocol, method and the like and description related to the HTTP request.

Specifically, the application sends an Http message to the gateway call micro-center to acquire a service interface of the Token according to the AppId and the AppSecret, and the gateway call micro-center is used for temporarily accessing the Token; the request Mqtt message content algorithm is described as follows:

the description of the algorithm is specifically shown in table 1;

TABLE 1 request Mqtt message content Algorithm description

3. The Mqtt Server distributes data to the edge computing gateway; the protocol conversion module on the edge computing gateway receives the data packet distributed by the Mqtt Server, analyzes the HTTP related information carried in the data packet, constructs an HTTP request according to the HTTP related information, and initiates the HTTP request to the local service; the protocol conversion module receives the HTTP response request of the local service, converts the response request into an Mqtt data packet and sends the Mqtt data packet to an Mqtt Server, wherein the Mqtt Server contains the content of the HTTP response request.

Specifically, the application sends a message to the gateway according to Token to call the service corresponding to the micro-center; the request response algorithm is described as follows:

the specific description of the algorithm content is shown in table 2;

TABLE 2 request Mqtt message content Algorithm description

4. After receiving the response message, mqtt Server forwards the response message to the application.

Specifically, the application listens for status and data information Topic receives the Mqtt message, containing the device status and sensor data.
