The invention discloses an internet-of-things multi-device intelligent tunnel security penetration interconnection system and an internet-of-things multi-device intelligent tunnel security penetration interconnection method. The system comprises a management end, an equipment end and a cloud end. The management end integrates an intelligent connection management layer, an efficient data plane engine, a unified business operation layer and a dynamic strategy and control center. The intelligent connection management layer dynamically selects an optimal tunnel link through a pluggable protocol framework; the efficient data plane engine intelligently switches multiple modes such as an original socket, libpcap and the like to perform high-performance data capture and filtration according to authority and requirements; the unified service operation layer deeply integrates operation and maintenance tools such as an embedded Web browser and an SSH terminal into a single interface; and the dynamic policy center can issue network rules in real time. According to the method, high-reliability and low-delay tunnel connection in a complex network environment is realized, refined flow control is driven based on service intention, and functions of network penetration, state monitoring, configuration maintenance and the like are seamlessly fused.

The invention provides a WAN interface detection method and device, electronic equipment and a readable storage medium. The method is applied to a target router, and comprises the following steps: in response to monitoring that first equipment is connected to a target to-be-detected interface, binding a first original socket with the target to-be-detected interface, and sending a generated target detection message to the target to-be-detected interface based on the first original socket, the target detection message is used for indicating first interface information of a target to-be-detected interface, and different to-be-detected interfaces correspond to different interface information; broadcasting the target detection message through a target to-be-detected interface, and when a first device connected with the target to-be-detected interface is a target device supporting a detection protocol, indicating the target device to generate a target response message by the target detection message; and in response to the received target response message, taking the target to-be-detected interface as the WAN interface. According to the method, the WAN interface can be efficiently determined.

This invention discloses a non-network layer-based communication system and method. The system includes a Layer 2 switch supporting Layer 2 forwarding capabilities, a first intranet machine, a second intranet machine, a first extranet machine, and a second extranet machine. Both the first and second intranet machines are connected to the Layer 2 switch via MAC interfaces. The first and second extranet machines are connected via an IP network. The first extranet machine connects to the first intranet machine via a MAC interface, and the second extranet machine connects to the second intranet machine via a MAC interface. In this invention, data between hosts in the intranet environment and between hosts in the intranet and extranet environments are processed using RAW Sockets combined with a custom data structure. This eliminates the need for network layer protocol forwarding, preventing the risk of network layer communication information leakage. Furthermore, the custom data structure allows users to define their own data filtering rules, increasing customization to adapt to different business or scenario operational requirements.
