Abstract	In order to dynamicly monitor and manage the working state of space science experiment payloads, the large volume of science data should be performed for real-time transmission. According to this requirement, the paper proposes a design scheme of main information network based on Ethernet. A microprocessor TMS320F2812 and the Ethernet interface chip KSZ8851 are applied to set up the Ethernet communication module of the payloads. The paper illuminates the hardware realization of the scheme with these two chips, as well as the software which is composed of drivers of transceiver register, the data definition of the telemetering data format and the data packing upon UDP/IP protocol. UDP protocol allows the fastest and simple way of transmitting data to the receiver. CCSDS packet format as a standard protocol in space data transformation is adopted in the UDP data packets. The experiment results show that the communication module can successfully transmit the data between Science Experiment Payloads and LAPTOP(or Data management unit) with a good real-time performance in the simple point-to-point circumstance.
