基于拓扑预测与LLDP控制的天基网络路由方法
Space?based network routing method based on topology prediction and LLDP control
摘要
Abstract
With the development of the software definition network(SDN),many space?based network architectures based on SDN have been proposed,in which the impact of sudden situation on the network topology and the reasonable use of link layer discovery protocol(LLDP)aren′t considered. In view of the above shortcomings,a space?based network routing method based on topology prediction and LLDP control(TP?LC)is proposed.The SDN?based network architecture is adopted in this method to close the LLDP in the normal situation,and calculate the path and send the flow chart directly according to the predicted topology;open the LLDP in the sudden situation,and calculate the path and send the flow chart after the real?time topology acquisition. In order to verify the TP?LC,a simulation platform based on SDN switch was established,which can simulate the characteristics of space?based network and SDN architecture simultaneously. The simulation results show that,in comparison with the open satellite net?work(Open?SAN),the method based on TP?LC can reduce the signaling overhead and data loss.关键词
