摘要
應(yīng)用層的網(wǎng)絡(luò)管理是很多中小型企業(yè)在信息化的過程中所面臨的難題之一。企業(yè)的管理者要保證企業(yè)的網(wǎng)絡(luò)資源用于正常的工作而不是被濫用，除了從制度方面進(jìn)行限制之外，一個(gè)應(yīng)用層網(wǎng)絡(luò)管理系統(tǒng)是不可缺少的。本文在對(duì)用戶需求進(jìn)行分析的基礎(chǔ)上，設(shè)計(jì)和實(shí)現(xiàn)了一個(gè)基于GNU/Linux和自由軟件的應(yīng)用層網(wǎng)關(guān)系統(tǒng)，并制作了一套基于B/S結(jié)構(gòu)的網(wǎng)關(guān)管理軟件對(duì)網(wǎng)關(guān)過濾規(guī)則進(jìn)行管理和維護(hù)。本文力求在理論研究的基礎(chǔ)上對(duì)應(yīng)用層的網(wǎng)絡(luò)管理問題給出一種靈活、有效、可靠且低成本的解決方案。

Abstract
Network management of application layer is one of the difficult problems for the medium and minor enterprise informatization. The administrators of enterprises want to make sure the network resources of enterprises are used in the normal work instead of abusing, so they must limit from the institution, and a network management system of application layer is indispensable. This text has designed and realized an application layer gateway that based on GNU/Linux and other free software, make network gateway management software, which based on B/S structure to manage and maintain filter rule. This text tries to provide a flexible, valid, reliable and low cost solution for resolve the problem of application layer network management based on theoretical research.
Keywords: Network gateway of application layer, GNU/Linux、iptables、layer7
