The study of dynamic topology remapping in virtual network embedding
Hang Li, Tianyang Zhou, Qingxian Wang · 2015
Virtual network Embedding (VNE) is recognized as the fundamental issue in network virtualization. Previous work in VNE mainly focused on researching efficient static algorithms without considering the dynamic topology remapping which may have an impact on the mapping efficiency. In this paper, we address the dynamic topology remapping problem and give a classification to clarify the remapping approaches under any circumstances. We find that choosing different strategies between timing, object and algorithm will affect the further mapping schemes.
