摘要
海上船舶移动通信是指船舶电台之间、船舶与基站电台之间的通信,目前应用范围最广的海上移动通信方式是VHF天线,尽管VHF具有成本低、结构简单等优点,但同时存在着信号传输质量差、抗干扰能力差等问题,因此,有必要对海上船舶的移动通信网络进行升级。IPV6协议是新一代网络通信协议,本文基于IPV6协议,研究船舶移动通信网络中SDN网络体系架构,并重点研究了通信网络的报文格式和数据转发等技术,对改善海上船舶移动通信网络的通信质量、抗干扰能力、数据传输能力有重要意义。
Marine ship mobile communication refers to the communication between ship radio stations and between ship and base station radio stations.At present,the most widely used mode of marine mobile communication is VHF antenna.Although VHF has the advantages of low cost and simple structure,it also has the problems of poor signal transmission quality and poor anti-jamming ability.Therefore,it is necessary to carry out the mobile communication network for ships on the sea.Upgrade.IPV6 protocol is a new generation of network communication protocol.Based on IPV6 protocol,this paper studies the SDN network architecture of ship mobile communication network,and focuses on the message format and data forwarding technology of communication network.It is of great significance to improve the communication quality,anti-interference ability and data transmission ability of marine mobile communication network.
