摘　　要：为保证船用网络通信的稳定性、可靠性,避免通信过程中数据丢失,研究5G通信技术的船用网络防拥塞机制。该机制结合船用网络数据传输场景的数据传输情况,分析其拥塞原因,引入5G技术设计和规划船用网络结构,计算网络链路带宽和资源分配情况,依据该计算结果,通过节点-链路控制方法计算网络中和链路关联节点的平均功率,依据计算结果对节点进行判定,再依据资源分配策略进行资源分配,以此有效降低船用网络的拥塞现象。测试结果表明,该机制应用后,船用网络的拥塞窗口大小明显降低,最大值仅为151.6 kB;并且网络碰撞概率值均在0.15以下,依旧满足期望应用标准,可有效处理船用网络防拥塞情况。In order to ensure the stability and reliability of marine network communication and avoid data loss during the communication process,the anti congestion mechanism of 5G communication technology for marine networks is studied.This mechanism combines the data transmission situation of the marine network data transmission scenario,analyzes the reasons for congestion,introduces 5G technology to design and plan the marine network structure,calculates the network link bandwidth and resource allocation,and based on the calculation results,calculates the average power of the network and link associated nodes through the node link control method.Based on the calculation results,the nodes are judged,and then resource allocation is carried out according to the resource allocation strategy,effectively reducing the congestion phenomen-on of the marine network.The test results show that after the application of this mechanism,the congestion window size of the marine network is significantly reduced,with a maximum value of only 151.6 Kbytes;And the network collision probab-ility values are all below 0.15,still meeting the expected application standards and effectively handling the anti congestion situation ofmarine networks.
