【摘要】:網(wǎng)絡虛擬化旨在解決現(xiàn)代網(wǎng)絡架構的僵化問題。虛擬網(wǎng)絡映射是網(wǎng)絡虛擬化的一個重要研究點,目前已經(jīng)有多種虛擬網(wǎng)絡映射算法,因此急需一個集成仿真平臺用于算法的性能比較。ALEVIN是虛擬網(wǎng)絡影射的代表性開源仿真平臺,集成了許多啟發(fā)式算法,但ALEVIN不能自由生成網(wǎng)絡拓撲環(huán)境。為彌補ALEVIN該缺陷,文中在ALEVIN上設計和實現(xiàn)了該功能,且開源可下載。此外,文中提出了一種精確解影射算法并添加到ALEVIN中。同時啟用添加的網(wǎng)絡拓撲環(huán)境生成功能,將該精確解算法與典型的啟發(fā)式算法進行了性能比較。
[Abstract]:Network virtualization aims to solve the rigid problem of modern network architecture. Virtual network mapping is an important research point in network virtualization. At present, there are many virtual network mapping algorithms. Therefore, there is an urgent need for an integrated simulation platform to compare the performance of the algorithm. ALEVIN is a representative open source simulation platform for virtual network mapping. Many heuristic algorithms are integrated, but ALEVIN can not generate network topology environment freely. In order to make up for this defect of ALEVIN, this function is designed and implemented on ALEVIN, and the open source is downloadable. In addition, an exact unmapping algorithm is proposed and added to ALEVIN. At the same time, the added network topology environment generation function is enabled, and the performance of the exact solution algorithm is compared with that of the typical heuristic algorithm.
