网络环境下全球影像的高效传输与调度策略

Effective global image delivery and dispatch strategies in net environment

本文针对网络环境下实现全球影像数据的快速可视化所涉及的数据组织和传输调度策略等关键技术进行了探讨。在计算机屏幕分辨率限制的基础上,对全球数据的分块方法进行了优化,并提出了智能控制的多线程网络传输技术和多级缓存的数据流机制,最后通过实验表明,该技术方案是切实可行的,能够平稳快速地对全球范围内TB级影像数据进行浏览,满足了C/S模式下大规模影像数据实时漫游的要求。

This paper discussed the key techniques of quick global image data visualization in net environment, such as the data organization, data delivery and dispatch techniques. It optimized the global data partition method according to the restriction of computer monitor resolution, presented the muhi-buffer data stream mechanism and the multi-thread net transferring techniques under intelligent control. The experiment showed that the techniques could be feasible to realize smooth and quick browsing of TB-level image data in global scale and meet the demands of real-time visualization of large-scale image data in C/S mode.
