针对在船队航行过程中，由于网络通信不稳定引起的P2 P分布式系统节点频发的退出问题，通过优化P2 P分布式架构的容错策略，提高系统的抗灾能力。探讨并设计在海洋环境下分布式系统的容错机制，提出更加适用于全新容错机制的节点选举方法，提高节点选举的可靠性和稳定性。在优化的P2 P架构下，设计并实现基于船队出海环境的分布式数据平台原型系统。通过仿真实验证明该系统具有较好的可伸缩性、独立性和稳定性。

This study,based on the frequent logouts of the P2P distributed system nodes due to the unsteady network communication during the voyage,aims to optimize the fault-tolerant strategies for P2P distributed structure and promote the system’ s ability to cope with disasters. It also explores and designs the fault-tolerant mechanism for distributed system in ocean environments, and specifies node selection methods more applicable to brand new fault-tolerant mechanism which improves the reliability and stability of the node selection. With the optimization of the P2P structure,the study designs and tests the distributed data platform prototype system for the ocean environment. With simulation experiments, the study proves that the system boasts strong flexibility,independence and stability.
