Abstract:

Network virtualization has been proposed as a promising way for expanding the network architecture.However,how to provide reliable VN against substrate infrastructure failures has become an increasingly important issue.Meanwhile the substrate network resource cost should be minimized under VN reliability guarantees to maximize the revenue for the in-frastructure providers (InP).A novel heuristic VN mapping algorithm was presented.Simulation results show that proposed algorithm can gain near optimal network bandwidth usage compared to the previous algorithms.

Key words: network virtualization, virtual network mapping, heuristic
