天地一体化网络结构复杂,并且存在网络异构、拓扑动态、间歇连通、节点高度暴露等特性,传统SDN实现存在诸多限制,提出了一种基于端侧计算的SDN实现方法,基于SDN理念实现的天地一体化信息网络,将天基网络控制与数据分离,利用通信端(移动终端和固定地面骨干网络)的计算能力,卸载天基平面的SDN控制器的计算工作量,从而实现了数据转发平面的极大简化,并提出了切实有效的验证方法。
There is a complex network structure of space-ground integrated network.And this kind of network has heterogeneous network
dynamic topology
intermittently connected node height exposure
and so on.There are many limitations in traditional SDN implementation.A method of SDN implement based on end side computing and a space-ground integrated network based on SDN were presented
which separated space network control and data
using the computing power of the communication terminal (mobile terminal and fixed ground backbone network)
unloading the calculation of SDN controller in space-based plane
thus simplifying the data forwarding plane.A practical and effective verification method was also proposed.
