摘要
针对国内对天地一体化的需求,提出一种基于NDP协议的IPv6 over AOS星间链路通信系统,将IPv6数据包封装在AOS帧中,通过激光在空间中传输,融合了地面网络与空间网络,满足了现阶段数据传输的高速、大容量需求。以FPGA作为网关,实现了网关及其子网之间的地址解析功能以及路由表的动态配置。结合MPLS技术,基于标签来进行路由决策,相比于原有基于IP路由进行转发的交换方式降低了组网成本,提升同样性能设备的转发效率,具有良好的可扩展性。
In order to meet the requirements of space-earth integration,an IPv6 over AOS intersatellite link communication system based on NDP protocol is proposed to encapsulate IPv6 packet into AOS frame and enable transmission in space by laser,integrating space network and ground network and meeting the needs of high speed and large capacity of data transmission at this stage.FPGA is regarded as gateway to realize the address resolution between gateways and subnets and dynamic configuration of the routing table.Combined with MPLS technology,the system makes routing decisions based on the label,reducing networking costs and improving forwarding efficiency of the equipment of the same performance.Compared with the forwarding mode based on IP routing,this method has good scalability.
