摘要
结合宽带卫星光网络的特点 ,基于MPLS(Multi -ProtocolLabelSwitching)的控制技术、SCMA(SubcarrierMultipleAccess)多址技术和WDM (WavelengthDivisionMultiplexing)光路由技术 ,提出了一种新型基于微波副载波 /光波长的双层路由技术方案 ,建立了一种简化的、灵活高效的卫星网络体系结构 ,给出了一种相应的启发式星上路由和信道分配RCA (RoutingandChannelAssignment)算法 ,分析了星上副载波 /波长路由器的具体结构和相关实现技术 .
According to the characteristics of the optical satellite networks,and on the basis of the control plane technology of MPLS(Multi-Protocol Label Switching)、SCMA multi-addressing technology and WDM/WR optical networking technology,a novel two-layered routing technology of sub-carrier/wavelength in satellite networks and a new concept of“target satellite data stream”are presented.Then a simplified and flexible systematic strutune of satellite networks with high efficiency is set up.Meanwhile a related optimal heuristic algorithm about routing and sources on satellites is developed and the structure of sub-carrier/wavelength routing and some related technologies are analyzed in details.
