【正文】 s，ranging from social networks to manmade technological networks. It seems that powerlaw is ubiquitous. However, it is undesirable for people to draw the conclusion that a new network shows powerlaw distribution just by plotting the node degree distribution in loglog scale without considering the evolution mechanisms of the network itself. For example, the network evolution mechanisms have not been considered in the characterization of the recently popularized P2P network. After exploring the evolution mechanisms of the P2P network, we show both analytically and by simulation that P2P network in fact follows exponential degree distribution rather than powerlaw distribution.Keywords: Powerlaw, P2P network, topology 第一作者簡(jiǎn)介: 張國(guó)強(qiáng), 1980年出生, 男, 江蘇常州人, 博士研究生, 主要研究方向?yàn)榫W(wǎng)絡(luò)管理, 互連網(wǎng)拓?fù)浒l(fā)現(xiàn)和拓?fù)浣? 主要發(fā)表的論文和專利有:[1] 張國(guó)強(qiáng), 張國(guó)清, 李仰耀. “物理網(wǎng)絡(luò)拓?fù)浒l(fā)現(xiàn)算法的研究和系統(tǒng)實(shí)現(xiàn)” 小型微型計(jì)算機(jī)系統(tǒng) 已錄用[2] 張國(guó)強(qiáng), 張國(guó)清. “Internet網(wǎng)絡(luò)的關(guān)聯(lián)性研究” 軟件學(xué)報(bào) 已錄用[3] Shi Zhou, Guoqiang Zhang and Guoqing Zhang. “The Chinese Internet ASlevel Topology” IEEE Journal on Selected Areas in Communications, submitted.[4] 張國(guó)清,張國(guó)強(qiáng),鄭海 “一種物理網(wǎng)絡(luò)拓?fù)浒l(fā)現(xiàn)系統(tǒng)及其方法” [5] 張國(guó)強(qiáng),張國(guó)清 “物理網(wǎng)絡(luò)拓?fù)浒l(fā)現(xiàn)中“啞元”設(shè)備的推測(cè)方法” [6] 張國(guó)強(qiáng),張國(guó)清. 專利“基于全局Internet拓?fù)渲R(shí)的P2P應(yīng)用構(gòu)建方法” 已提交。通過仔細(xì)分析提出P2P網(wǎng)絡(luò)服從冪律的兩個(gè)原始圖，我們發(fā)現(xiàn)這兩個(gè)圖實(shí)際更符合負(fù)指數(shù)分布而非作者所說的冪律分布。正確地刻畫新的網(wǎng)絡(luò)的方法必
