采用基于Openstack搭建云计算平台服务器和服务器＋两级客户端的三层架构网络通信两种技术结合的设计方案。网络拓扑结构采用服务器＋一级客户端＋二级客户端的三层网络拓扑结构，服务器和一级客户端基于TCP/IP协议传输数据，一级客户端和二级客户端在分控中心局域网内部基于UDP协议广播传输数据。在服务器端，构建一个基于Openstack的云计算资源共享平台，实现通信服务器、数据库服务器、应用服务器、AIS分发与解码服务器共享多台主机硬件资源，实现计算资源的虚拟化管理，提高资源的利用率。实际应用表明，该通信软件运行可靠，传输稳定，可保证海量数据的实时传输。

The design scheme integrating three level communi-cation architecture of server +two level clients and cloud computing platform based on Openstack was adopted .Network topology of the software is server +first level client +second level client , where communication between server and first level client is through TCP/IP protocol and communication be-tween first level client and second level client is through UDP broadcast protocol in local area network of the sub-control center.For the server side, a cloud computing resource sha-ring system based on Openstack is realized to take full advan-tage of the server resource .By this way , communication serv-er, database server, application server and AIS data distribu-tion /decoding server can share hardware resource of multiple hosts and manage computing resources virtually , which impro-ving resources occupation percentage and optimizing server performance .Practical application shows the reliability and robustness of the software , which can ensure real-time com-munication for large amount data .
