In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
The invention is applied to the field of edge calculation and aims to solve the access problem of edge equipment. Along with the development of network technology and hardware technology, the internet of things is greatly developed, intelligent (networking) terminal devices which are visible in life are more and more, if the huge internet of things terminal devices are managed in a traditional PC network access mode, a plurality of huge network channels are required to be established, namely, corresponding bidirectional TCP connection is established with each internet of things device, but because the data interaction frequency between the internet of things terminal devices and the servers corresponding to the back ends is not high, and the operation instructions and/or data of the back end servers are received passively, the transmission of network data is usually that the back end servers firstly send corresponding instructions, and therefore, a large amount of TCP connection resources on the servers are wasted. And because IPV6 is not fully popularized, a large number of terminal devices are still deployed in an IPV4 manner, and in the layer-by-layer NAT network, when TCP connection is not continuously established, the backend server cannot actively connect to the corresponding terminal devices (multiple terminals share an IPV4 address to form a network in a NAT mapping manner). Therefore, the access and management of the existing edge equipment is high in construction cost and maintenance cost.

and deleting the central agency module from the relation mapping table in response to the central agency module not responding to the heartbeat detection.
3. The system of claim 2, wherein the central proxy module is further configured to:
and in response to successful data channel registration of the edge proxy module and the central proxy module, acquiring the IP address and the unique identifier of the edge proxy module, and adding the IP address, the unique identifier and the IP address of the central proxy module to the relation mapping table copy.
4. The system of claim 1, wherein the central proxy module is further configured to:
generating an identification code of the operation instruction and/or the data based on the data length of the operation instruction and/or the data and the identification information of the operation and maintenance management platform; and
encrypting the operation instruction and/or data and the identification code and sending the encrypted operation instruction and/or data to an edge proxy module.
5. The system of claim 1, wherein the edge proxy module is further configured to:
and responding to the received corresponding operation instruction and/or data, executing the operation instruction and/or data on the edge proxy module, generating a response identification code of the operation instruction and/or data by the data length of the execution result and the identification information of the operation and maintenance management platform, encrypting the response identification code and the execution result data of the operation instruction and/or data, and then transmitting the encrypted response identification code and the encrypted execution result data of the operation instruction and/or data to the central proxy module.
6. The system of claim 5, wherein the central proxy module is further configured to:
in response to receiving the encrypted data sent by the edge proxy module, decrypting the encrypted data to obtain a corresponding response identification code and execution result data of the operation instruction and/or data;
analyzing the response identification code according to the generation mode of the response identification code, and sending the execution result data of the operation instruction and/or the data to the operation and maintenance management platform according to the unique identification of the operation and maintenance management platform in the identification code.
7. The system of claim 3, wherein the central proxy module is further configured to:
and sending heartbeat detection to the edge proxy module at predetermined time intervals, and deleting the edge proxy module from the relation mapping table copy in response to the edge proxy module not responding to the heartbeat detection.
8. A server cluster, one or more server nodes of the server cluster being deployed with corresponding modules in the system of any of claims 1-7.
