1、蘭州大學(xué)碩士學(xué)位論文分布式網(wǎng)絡(luò)流量監(jiān)控系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)摘要網(wǎng)絡(luò)的應(yīng)用形式由傳統(tǒng)業(yè)務(wù)向P2P、Web2.0等形式轉(zhuǎn)移,急需高效的流量監(jiān)控系統(tǒng)對網(wǎng)絡(luò)的各類業(yè)務(wù)進(jìn)行及時(shí)、準(zhǔn)確的分析和控制。本論文以”基于IPv6的P2P彈性重疊網(wǎng)絡(luò)智能節(jié)點(diǎn)的研制(CNGI-04-12-1D)”項(xiàng)目為研究背景,設(shè)計(jì)并實(shí)現(xiàn)了一種新的基于分布式的網(wǎng)絡(luò)流量監(jiān)控系統(tǒng)。本論文的主要研究內(nèi)容:1、研究了兩種流量監(jiān)控系統(tǒng)的架構(gòu)方案,結(jié)合項(xiàng)目總體技術(shù)要求,采用分布式架構(gòu)方案,實(shí)現(xiàn)對網(wǎng)絡(luò)的多個(gè)關(guān)鍵出口實(shí)時(shí)高效的監(jiān)控。2、研究了監(jiān)控系統(tǒng)的網(wǎng)絡(luò)數(shù)據(jù)采集技術(shù)及接入網(wǎng)絡(luò)方式(串聯(lián)、旁路),并根據(jù)項(xiàng)目的實(shí)際
2、需求,采用旁路接入方式對網(wǎng)絡(luò)進(jìn)行監(jiān)控。3、研究了當(dāng)前的端口匹配、特征碼匹配技術(shù)以及流量控制技術(shù),設(shè)計(jì)并實(shí)現(xiàn)了基于應(yīng)用層協(xié)議監(jiān)控策略動(dòng)態(tài)配置技術(shù),采用一次匹配、二次匹配、PASVF『P匹配相結(jié)合的應(yīng)用層協(xié)議分析技術(shù)和優(yōu)化的TCP流量旁路阻斷技術(shù)的網(wǎng)絡(luò)流量監(jiān)控系統(tǒng)。4、對該系統(tǒng)的功能和性能進(jìn)行了測試,測試結(jié)果表明該系統(tǒng)的功能達(dá)到了設(shè)計(jì)要求,具有很好的穩(wěn)定性、可擴(kuò)展性和可操作性等優(yōu)點(diǎn)。論文的創(chuàng)新之處:為優(yōu)化應(yīng)用層協(xié)議的分析與統(tǒng)計(jì)性能,提出了應(yīng)用層協(xié)議監(jiān)控策略動(dòng)態(tài)配置技術(shù),組合了一次匹配、二次匹配和PASV_FTP匹配等應(yīng)用層協(xié)議分析技術(shù),同時(shí)對TCP流量旁路阻
