Study on Carrier-Level Optimization of Virtual Network Embedding
Liu Y · Journal of Nanjing University of Posts and Telecommunications · 2014
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.
