Virtual network embedding in cross-domain network based on topology and resource attributes

摘要：

　　Aiming at the network architecture ossification and the diversity of access technologies issues,this paper researches the cross-domain virtual network embedding algorithm.By analysing the topological attribute from the local and global perspective of nodes in the virtual network and the physical network,combined with the local network resource property,we rank the embedding priority of the nodes with PCA and TOPSIS methods.Besides,the link load distribution is considered.Above all,We proposed an cross-domain virtual network embedding algorithm based on topology and resource attributes.The simulation results depicts that our algorithm increases the acceptance rate of multi-domain virtual network requests,compared with the existing virtual network embedding algorithm.
