Data interaction system for end node equipment in satellite-borne real-time network

The invention relates to the field of satellite communication system design and network transmission design, and provides a data interaction system for end node equipment in a satellite-borne real-time network. End node IP core external interfaces of the device comprise a host port, a synchronization port and a plurality of data ports, construction and data transmission of satellite-borne high-reliability real-time network end nodes can be quickly realized by matching with different functional devices according to actual application requirements, transmission messages are processed by layers in end node devices based on time scheduling, and data transmission efficiency is improved. The system further comprises a timestamp processing layer, an arrival time scheduling and departure time scheduling layer, a destination query and redundancy elimination layer and an exchange switch layer. The design of the end node IP core formed by the invention is convenient to integrate in a programmable logic device; the desig
