Embodiment 1

[0036] This embodiment provides a real-time security network system based on dual-engine forwarding, such as figure 1 shown.

[0037] A real-time security network system based on dual-engine forwarding, including a dual-engine security switch, the dual-engine security switch is connected to a real-time node and a data node respectively, the dual-engine security switch includes a PHY chip, and the PHY chip is respectively connected to a leaf interface, a dual engine chip and backbone interface; the dual-engine chip includes a source engine and a common engine, the real-time node is provided with a real-time node control chip, and the dual-engine security switch adopts a cell transmission mode, and the real-time node is embedded in the operating machine Or directly connected with the machine, in order to achieve higher real-time performance; the data node is a kind of data communication equipment or device, connected to the common data network and IT network, and the common node...

Embodiment 2

[0062]This embodiment discloses a non-blocking transmission based on a train timetable applying the present invention, such as figure 2 shown.

[0063] figure 2 It is a schematic diagram of non-blocking transmission based on a train timetable. The present invention has a time trigger at a real-time node, which is analogous to a train departure timetable. The domain controller passes the backbone interface to the backbone interface; the real-time node to the leaf interface performs time measurement, and the forwarding delay is fixed, so the domain controller forwards all real-time streams to the time slots of the incoming and outgoing time slots into cloud computing based on the SDX idea , and then through each interface issued by the domain controller and the real-time node. Cloud computing based on the SDX idea will realize zero-delay non-blocking forwarding in the exit direction of each node, which is very similar to the case where a series of high-speed trains pass thro...

Embodiment 3

[0065] This embodiment discloses a PHY design based on the shoot-through low-latency design of the present invention. The core PHY design is based on the low-latency design of the shoot-through. After the data received by the PHY is directly encrypted and decrypted through the FIFO memory, it is directly sent to the serial deserializer. The ultra-low-latency circuit design makes the delay possible. Reach <50ns, and the serial deserializer also adopts ultra-low delay circuit design, so that the delay is also <50ns

Abstract

The invention relates to the technical field of network security, in particular to a real-time secure network system based on dual-engine forwarding. The real-time secure network system based on dual-engine forwarding comprises dual-engine security switches; the dual-engine security switches are connected with real-time nodes and data nodes respectively; each dual-engine security switch comprisesa PHY chip; and the PHY chip is connected with a leaf interface, a dual-engine chip and a backbone interface respectively. A physical network is isolated to two completely non-interactive and non-interference networks, one network is regarded as a common network compatible with the existing common network, the other network is a real-time network used by an OT, super high secure and super high real-time design is adopted, and the performance is excellent.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a real-time security network system based on dual-engine forwarding. Background technique [0002] With the vigorous development of Industry 4.0 intelligent manufacturing, IT information technology, OT operation technology and CT communication technology need to be greatly integrated. These networks need to be integrated into one network. What comes is production efficiency, and safety brings production safety, including life and property safety, and IT has external access networks, which require a super-real-time and super-secure network, and the cost of investing in network security is also high. No more. [0003] Important functional departments of the country, such as power grids, transportation, government, and the military, are generally divided into internal networks and external networks, emphasizing the absolute security and isolation of the network, authority ...
