  • 摘要: 虛擬網(wǎng)映射是網(wǎng)絡(luò)虛擬化研究中亟待解決的問題,針對已有映射算法中存在的對于網(wǎng)絡(luò)拓?fù)湫畔⒗貌蛔愕默F(xiàn)狀,該文提出了基于資源區(qū)域聚集度的虛擬網(wǎng)映射算法(RCI-VNE)。在映射預(yù)處理階段,根據(jù)局部拓?fù)湫畔⒑蛥^(qū)域資源聚集度提出節(jié)點(diǎn)區(qū)域資源聚集評價算法。在節(jié)點(diǎn)映射階段,提出一種基于節(jié)點(diǎn)區(qū)域資源聚集排名的2-近鄰聚集映射算法,該算法將虛擬網(wǎng)節(jié)點(diǎn)集中映射到底層網(wǎng)絡(luò)中可用資源豐富的區(qū)域,減小承載鏈路的長度。實驗結(jié)果表明,該算法降低了虛擬網(wǎng)映射開銷,且具有較高的虛擬網(wǎng)請求接受率和較低的平均執(zhí)行時間。
