Cooperative Control Method of Multi Agent Satellite System Based on SDN

In view of the problems of inflexible routing strategy, poor compatibility and high deployment cost of satellite network, this paper proposes a software-based collaborative control method for multi-agent satellite system based on software definition: high orbit satellite as the main control node and storage task software, Leo layer part of nodes as slave control nodes The flow table and program information are distributed to the slave nodes in a region, and the effective control of multi-agent satellite system is realized. The experimental results show that the proposed satellite network architecture and the delay based algorithm can effectively reconfigure the in orbit function, and the network delay is 10% lower than the general controller selection algorithm.
