IP OVER CCSDS协议网关设计

Design on IP OVER CCSDS Protocol Gateway

随着我国载人航天、深空探测等领域的发展,空间传输网络与地面传输网络的融合已经越来越紧密。针对地面网络IP协议与空间网络CCSDS AOS协议转换设备的迫切需求,在以太网接口芯片和FPGA TEMAC接口IP内核的基础上进行设计,提出了一种IP协议与CCSDS AOS协议转换设计方案。采用该方案实现的设备已经进行了试验和验证,结果表明,IP OVER CCSDS协议网关达到了设计指标要求,可在基于IP业务的天-地传输系统中推广使用。

As the development of manned space program and deep space exploration, the convergence of space transmission net- work and earth transmission network becomes a trend.Aiming at inereasing demands for conversion device of IP protocol of earth network and CCSDS AOS protocol of space network,this paper presents a solution of IP protocol and CCSDS AOS protocol conversion based on Ethernet interface chip and FPGA TEMA interface IP kernel.The experiment and test are performed for the equipment which uses this solution.The results show that the IP OVER CCSDS protocol gateway can meet the design requirement and can be applied in IP-based space-earth transmission system.
