Embodiment Construction
[0025] Glossary:
[0026] MQTT: MQTT (Message Queuing Telemetry Transport) is a messaging protocol based on the publish / subscribe paradigm under the ISO standard (ISO / IEC PRF 20922). It works on the TCP / IP protocol family and is a publish / subscribe message protocol designed for remote devices with low hardware performance and poor network conditions.
[0027] WebDAV: WebDAV (Web-based Distributed Authoring and Versioning) is a distributed authoring and version management communication protocol based on the HTTP 1.1 protocol. It extends HTTP 1.1 and adds some new methods in addition to several HTTP standard methods such as GET, POST, HEAD, etc., so that the application can directly read and write to the Web Server, and supports writing file locking (Locking) and unlocking (Unlock) , can also support file version control.
[0028] Intranet: Enterprise Intranet, or Intranet, Intranet, Intranet, is a computer network that uses the same technology as the Internet (Internet), whic...

The invention discloses an intranet and extranet data communication system and method based on MQTT, and the system comprises a Web service module which is disposed in an intranet and is used for receiving request information and making a corresponding response, a client module which is used for directly accessing the Web service module or indirectly accessing the Web service module through an encryption link according to the state of the client module, a proxy service module which is arranged in an external network and is used for establishing communication connection with the client module based on MQTT and forwarding the received data through the encryption link, and a network bridge data exchange module which is arranged in an intranet, is connected with the Web service module, establishes communication connection with the proxy service module through the encryption link based on MQTT, and is used for exchanging data of the intranet and the extranet. The embodiment of the inventionat least has the beneficial effects that extra physical isolation equipment or a special safety platform is not needed, the cost is reduced, the data isolation of the intranet is kept, the intranet data can be safely accessed by the extranet in time, the coupling degree among the modules is low, and the later maintenance and updating are convenient.
Description
technical field [0001] The invention relates to the field of network data exchange, in particular to an MQTT-based internal and external network data communication system and a method thereof. Background technique [0002] Computer networks are widely used in many fields such as college teaching, e-commerce or automatic control. With the development of the Internet, more and more computers are connected to the Internet. Viruses and Trojan horse programs that mainly rely on the network to spread are becoming more and more worrying today when network communications are becoming more and more popular. Connections without security guarantees will expose users' computers to intrusions, attacks by criminals, and other threats on the Internet. serious threat. Some key departments often adopt the form of internal and external networks, in which the computer local area network is referred to as the internal network, and the wide area network is referred to as the external network. ...
