By controlling flood of link state information, LEO satellites could acquire local topology information to route the short-distance traffics. The long-distance traffics were routed in MEO layer.

通过控制链路状态信息的洪泛，LEO卫星只需掌握局部拓扑即可完成短距业务通信，长距通信业务则由MEO卫星承载。

This algorithm combined sub-carrier allocation in the physical(PHY) layer with traffic scheduling at the data link layer (DLL) by employing the channel state information.

利用物理层的信道状态信息，该算法将物理层（PHY）的子载波分配同数据链路层（DLL）的数据包业务调度结合起来。
