基于卫星网络的海事邮件通信系统架构设计

Design of the Marine Email Communication System Architecture in Satellite Network

设计基于卫星通信网络的海事邮件通信系统架构。通过分析卫星网络的高延时和带宽资源的特点,结合远洋交通运输船舶与陆地邮件通信的实际需求,研究邮件数据压缩、解压和私有Socket协议与SMTP邮件协议通信的技术,采用Java系统架构,在高延时和窄带宽的卫星网络中,实现船舶邮件通信和船员邮件服务。该架构通过压缩、断点续传和自动文件传输等技术,提高了邮件传输的效率,减少了卫星通信中数据流量的开销,提高了海事领域卫星通信的经济性、安全性和船岸信息化的水平。

The paper designs a mail system architecture of marine communication based on satellite communication network. By analyzing the characteristics of high latency and bandwidth resources of satellite network,and combining the actual requements of ocean transportation ships and land mail communication,this paper studies the technology of mail data compression,decompression and private Socket communication protocol with SMTP mail protocol. Using Java system architecture to realized mail communication and crew-mail service in satellite network that is high latency and narrow bandwidth. This architecture improves the efficiency of mail transmission through compression,breakpoint continuation and automatic file transmission,reduces the cost of data traffic in satellite communication,and improves the economy,security and the level of ship-shore informatization in maritime field.
