C/S模式下跨平台文件共享管理的设计与实现

The Design and Implementation on Across-platforms File-sharing Management Based on C/S mode

传统方式下在保证跨平台共享文件的访问安全性采用的是文件加锁机制。但锁机制在多客户和第三方软件并发访问共享文件时的安全性以及文件访问权限调度方面有很大的局限性。本文讨论了一种跨平台文件共享管理系统的实现机制。该系统能够保证多个客户进程与第三方软件进程安全、有效地使用服务器上的共享文件,并为客户进程提供通知机制以实现文件访问权限调度。

At the traditional mode, file-locking mechanisms can be applied to ensure the security of multi-platform shared files. However, file-locking mechanisms are deficient both in visiting security of sharing files about multiple client and third party software and in scheduling the read/write file authority. In this paper, the design and implementation of Across-platforms File-sharing Management System is discussed. The system not only satisfies the need for multiple client processes and third party process to u...
