【摘要】 随着数字信息化、网络化的各种多媒体处理业务的不断增加,借助计算机网络技术实现数据共享的需求不断提高。为满足这些需求,一种新兴的技术——虚拟存储,正越来越受到关注。虚拟存储实际上是一种逻辑存储思想,实质是对物理存储设备进行逻辑化的处理,克服了物理存储的局限性。它将若干个不同类型、独立存在的物理存储体,通过软硬件相关技术,模拟为一个逻辑上的虚拟存储单元,便于集中和统一管理、使用。而无线网络技术的发展,特别是随着3G技术和WiFi技术等通讯网络的发展,使得基于网络的无线虚拟存储得以很好的实现。本项目主要是用于高清视频文件的虚拟存储应用,系统的具体实现是基于嵌入式Linux系统和WiFi技术,通过TCP/IP网络通讯协议设计并实现一个无线的虚拟存储系统,使远端的嵌入式WiFi终端设备能够连接到网络,快速访问存储系统里的资源,满足用户无线上网及数据共享等多种服务需求。论文首先介绍了虚拟存储的概念和原理,再对文件系统、WiFi标准及无线局域网技术作了介绍,然后围绕本虚拟存储系统的实现原理,详细介绍了怎样构建系统软硬件开发环境,最后通过socket网络编程完成数据传输,从而真正实现虚拟存储的功能。更多还原

【Abstract】 With digital and multimedia process business of network increases, data sharing demands baseing on computer network technology are rising. In order to meet these requirements, an emerging technology --virtual storage, is increasingly more and more attracting peoples’ attention. The virtual storage is actually a logical storage. The essence of virtual storage is the logic processing of physical storage device. It overcomes many limitations of physical storage. It can integrated several different independent types of physical storage bodies into a virtual logical storage unit by the software and hardware technology. It can be centralizedly managed and uesed. The development of wireless network technology, especially with the development of 3G and WiFi communication network, making the virtual storage technology based on wireless network be well implemented.The main purpose of this project is for virtual high-definition video file storage applications.The wireless virtual storage system is based on embedded Linux systems and WiFi technology.It allows remote embedded PC equipments connected to network and fast accesses resources.It can supply convenient entertainment services of wireless Internet access and data sharing for users.Thesis first introduces the concepts and principles of virtual memory.The file system, WiFi standards and wireless LAN technology are also introduced. And then around the principle of this virtual storage system, detailedly describing how to build the system software and hardware development environment. Data transmission can be completed by the aid of socket network programming. Finally, the function of virtual storage truly achieves.更多还原
