Membrane Computing Based Virtual Network Embedding Algorithm with Path Splitting

Network virtualization is recognized as an important enabler technology to diversify the future Internet and the Virtual Network Embedding problem is major challenge to fulfill it. In this paper, we proposed a parallel Virtual Network Embedding algorithm with Path splitting on the basis of membrane Computing (VNEPC). And more importantly, it is one phase embedding algorithm that maps virtual nodes and virtual links in the same phase without decomposing the VNE problem. Extensive simulation results show that our proposed VNEPC algorithm outperforms the existing algorithms in long-term average revenue, acceptance ratio and long-term R/C ratio.
