Bridging virtualized environments with physical environments, virtual network plays an important role in Cloud Computing infrastructures.How to allocate physical resources for virtual nodes/links to construct virtual network is known as Virtual Network Embedding (VNE) problem.It is a crucial issue that draws wide attention.This paper surveys existing VNE methods and algorithms and how they work under different application scenarios.First, a survey of different VNE objective metrics is presented; then several VNE algorithms are presented and categorized; finally, the performance of different VNE solutions are compared and discussed.
