Abstract


Service-oriented network virtualization enables a Network-as-a-Service paradigm to be available in cloud computing, thereby allowing network infrastructures to be exposed and utilized on demand. Virtual network embedding is a core network virtualization technique; however, a number of conflicting embedding objectives must be accommodated when implementing virtual network embedding. In this paper, we propose a multi-objective virtual network embedding framework to balance various mapping (or embedding) objectives. In addition, we apply an improved multi-objective group search optimizer to solve the virtual network embedding problem and generate trade-off solutions. Experimental results suggest that multi-objective virtual network embedding can balance various mapping objectives while achieving excellent results for acceptance ratios and revenue.
