Abstract: How to implement the unblocked end-to-end communication between the space and the ground is a key technology in the design of the telescience network. This paper puts forward a design scheme of the translation gateway between CCSDS standard and TCP/IP protocols. The scheme adopts multi-process structure, pre-establishment technology and hierarchical modularized architecture to improve the performance of the gateway. At last, the paper gives out the implementation flow and the performance testing results of the gateway.
