基于J2EE的分布式海量影像分发服务研究和实现

A Study and Implementation of the Distributed Publication Service of Massive Imagery Data Based on J2EE

为实现分布式海量影像分发服务,提出了基于J2EE的分布式海量影像数据分发服务架构,并重点探讨海量影像数据的索引、影像分发服务的多级缓存、基于服务集群的分发服务等关键技术,最后利用VC++6.0、EVC++4.0、Jbuilder2005等开发工具实现了海量影像动态分发服务系统,分别在局域网和海事卫星网络两种网络条件下进行了实验与分析。

To realize the distributed publication service of massive imagery data, a J2EE-based distribution service structure is initiated. It is concentrated on several key techniques, including index of massive imagery data, multi-cache strategy, and multi-server cluster technology. A dynamic publication system of massive imagery data has been developed. And the system is validated in a LAN and the maritime network, repectively.
