Research on SDN-based resilient network technology architecture for intelligent ships

Intelligent ships are the new trend of maritime transportation tools, in which the secure, reliable, flexible, and resilient communication network is the core technology of intelligent ships and the critical challenge faced. To address this, the paper systematically analyzed the network access terminal characteristics and requirements of intelligent ships, focusing on the study of the resilient network framework and topology structure of intelligent ships. It designed a high-resilience communication network technology architecture for intelligent ships based on Software-defined Networking (SDN). Building on a systematic analysis of resource utilization in intelligent ship resilient communication network, the paper proposed an intelligent ship resilient communication network fragility segmented dynamic monitoring strategy (IS-SDMS), which was deployed in the control system of the intelligent ship resilient communication network. This achieved reliable and flexible resource management and security monitoring of the communication network, effectively ensuring the network security of intelligent ships.
