【摘要】：隨著Internet的快速發(fā)展，網(wǎng)絡(luò)已經(jīng)成為人們重要的信息來源。對(duì)于已經(jīng)成為互聯(lián)網(wǎng)重要組成部分的P2P（Peer-to-Peer）網(wǎng)絡(luò)，每天都有大量的信息在該網(wǎng)絡(luò)中傳播。去中心化使得P2P網(wǎng)絡(luò)為不良資源提供了有效并快速的傳播途徑，而且難以管理。如何有效監(jiān)控P2P網(wǎng)絡(luò)是目前研究的方向。 本文在分析了P2P網(wǎng)絡(luò)數(shù)據(jù)傳輸協(xié)議的基礎(chǔ)上，深入研究P2P網(wǎng)絡(luò)信息監(jiān)督技術(shù)，基于高性能的Tilera多核設(shè)備，研究并實(shí)現(xiàn)一個(gè)高效的P2P網(wǎng)絡(luò)信息監(jiān)控系統(tǒng)；系統(tǒng)分為服務(wù)器端、客戶端以及數(shù)據(jù)庫，，有效高速的監(jiān)控P2P網(wǎng)絡(luò)，并對(duì)監(jiān)控結(jié)果進(jìn)行分析與處理。本文的主要工作包括以下幾方面： （1）設(shè)計(jì)并實(shí)現(xiàn)了基于Tilera多核處理器的監(jiān)控方式。根據(jù)多核以及監(jiān)控流程的特點(diǎn)，并依據(jù)系統(tǒng)各模塊的數(shù)據(jù)處理量，對(duì)多核進(jìn)行了分配，設(shè)計(jì)了數(shù)據(jù)處理流程的優(yōu)化策略；其主要思想是針對(duì)數(shù)據(jù)處理速度的不同，將串行處理任務(wù)，使負(fù)載均衡。 （2）根據(jù)系統(tǒng)需要對(duì)關(guān)鍵詞或者文件hash進(jìn)行多次重復(fù)監(jiān)控特點(diǎn)，對(duì)路由存儲(chǔ)機(jī)制進(jìn)行修改，提出了一種基于LRU的路由表維護(hù)策略，其主要思想就是讓有監(jiān)控結(jié)果的節(jié)點(diǎn)能在下一次監(jiān)控中有更大的優(yōu)先權(quán)。實(shí)驗(yàn)結(jié)果顯示，這樣的修改對(duì)于監(jiān)控結(jié)果的影響在合理范圍內(nèi)，而查詢跳數(shù)明顯減少。 （3）針對(duì)本系統(tǒng)，對(duì)數(shù)據(jù)庫進(jìn)行了設(shè)計(jì)并實(shí)現(xiàn)了客戶端軟件，讓用戶通過客戶端軟件可以方便的查詢監(jiān)控結(jié)果，增加、刪除、修改監(jiān)控關(guān)鍵詞，查看系統(tǒng)運(yùn)行狀態(tài)。
[Abstract]:With the rapid development of Internet, network has become an important source of information. P2P (Peer-to-Peer) network, which has become an important part of the Internet, has a large amount of information spread in the network every day. De-centralization makes P2P network provide an effective and fast way to propagate bad resources, and it is difficult to manage. How to monitor P2P network effectively is the research direction at present. In this paper, based on the analysis of P2P network data transmission protocol, the P2P network information monitoring technology is deeply studied. Based on the high-performance Tilera multi-core equipment, an efficient P2P network information monitoring system is studied and implemented. The system is divided into server, client and database to monitor P2P network effectively and high-speed, and analyze and process the monitoring results. The main work of this paper includes the following aspects: (1) the monitoring mode based on Tilera multi-core processor is designed and implemented. According to the characteristics of multi-core and monitoring process, and according to the data processing capacity of each module of the system, the multi-core is allocated, and the optimization strategy of data processing process is designed. Its main idea is to deal with the serial tasks according to the different speed of data processing, so as to make the load balance. (2) according to the characteristics of repeated monitoring of keyword or file hash, the routing storage mechanism is modified, and a routing table maintenance strategy based on LRU is proposed. The main idea is to allow nodes with monitoring results to have greater priority in the next monitoring. The experimental results show that the influence of such modifications on the monitoring results is within a reasonable range, while the number of query hops is obviously reduced. (3) according to this system, the database is designed and the client software is implemented, so that the user can query the monitoring results conveniently through the client software, add, delete, modify the monitoring keywords, and check the running status of the system.
