天地一体化信息网络在组网过程中会面临链路异构、信息多粒度和资源受限等挑战,通过数据交换设计可以解决这些问题。描述天地一体化信息网络架构,分析多粒度业务混合交换的现状,并在此基础上提出光/射频/分组混合交换的设计思想,主要包括混合交换结构设计、基于四波混频效应的光交换、宽带可配置射频信道化交换、基于软件无线电思想的分组高速交换、激光/射频异构链路光域聚合与疏导以及增强型GMPLS设计。
Space-integrated-ground information network will face the challenges of heterogeneous links
multi-granularity of information and limited resources in the process of networking.The problems can be solved by data switching design.The architecture of space-integrated-ground information network was described
and the present situation of multi-granularity service hybrid switching was analyzed.Based on this
the idea of hybrid optical/RF/packet switching was proposed
i.e.
hybrid switching structure design
optical switching based on four-wave mixing eff ect
broadband confi gurable RF channelized switching
packet high-speed switching based on software radio idea
laser/RF heterogeneous link optical domain aggregation and grooming and enhanced general multi-protocol label switching design.
