基于网络的微机机时和流量管理系统的设计与实现

Design and Implementation of Time and Flow Management System Based on Network

论述了为满足公共机房内微机管理的需要，设计并实现了的一个机时与流量管理系统。整个系统采用Ｃｌｉｅｎｄ／Ｓｅｒｖｅｒ结构，可以实现对多个公共机房用户的机时和流量进行统一的、自动化管理。还设计并实现了一个局域网内的ＩＰ数据包捕获和分析系统，详细论述了系统开发中应用的一些关键技术，如 ＵＮＩＸ操作系统基于流（ＳＴＲＥＡＭ）的 ＤＬＰＩ（Ｄａｔａ ＬｉｎｋＰｒｏｖｉｄｅｒ Ｉｎｔｅｒｆａｃｅ）接口等。

To meet the needs of the manmagement of open labs, this paper is designed and implemented for a management system on time and flow control. The system is based on the Client/Server structure, which can manage the time and flow control of each user in open labs automatically. Also, this paper illustrates the implementation of a IP capture and analysis system and dissertates the important tech- niques applied to the system, including DLPI (data link provider interface), which based on the STREAM mechanism of UNIX.
