Virtual Network with Security Guarantee Embedding Algorithms
Chiqiang Xing, Julong Lan, Yuxiang Hu · Journal of Computers · 2013
Network virtualization has been widely concerned as the new technology to remedy the current ossification Internet architecture. Previous virtual network (VN) embedding algorithms focus on optimizing the use of resources with regard to performance with constraints on virtual nodes and links. There are few researches to analyze the security threat to the virtual network. In this paper, we first present two security threats of virtual network and investigate them in depth. Then we propose a novel virtual network with security guarantee that will take the trust value and security protection level as the new security constraints during its embedding. The virtual network with security guarantee embedding algorithm is given at last, and the simulation results show that the algorithm is effective.
