深空探测器器间SDN网络架构设计OA

Deep space exploration missions are characterized by high dynamics,complex environ-mental occlusions,significant resource constraints,and heterogeneous nodes.In response to these challenges,an inter-spacecraft network implementation scheme based on a Software De-fined Networking(SDN)architecture is proposed.The designs of an on-board SDN controller and switch are detailed.Key performance metrics,including network establishment time,are an-alyzed.A simulation of network establishment time is conducted using a multi-probe lunar sur-face networking scenario.This study provides a reference for the design of inter-spacecraft net-work architectures in future deep space missions.
