| Abstract: | Network virtualization （NV） promises a most effective measure to overcome the ossifications of conventional Internet.Virtual network embedding （VNE） is one of key issues in NV development.This paper presents a summary by using a consistent optimal formulation over the current technologies of network resource allocation,including cost minimization,revenue maximization,residential resource maximization and energy saving maximization.The problems such as Service-Level-Agreement violation,intra-domain distribution and game mechanism design,are discussed aiming at a carrier-level VNE solution.The paper provides in the further the method for dynamic topology adaptation,access and reliability control,and a modeling means for energy savings by using the proportional computing techniques. |
