چکیده انگلیسی
The virtual network embedding/mapping problem is a core issue of the network virtualization. It's mainly concerned with how to map virtual network requests to the substrate network efficiently. Previous researches mainly focus on developing heuristic algorithms for general topology virtual network request. In this paper, we propose a new algorithm for the hub-and-spoke (HAS) topology virtual request. The characters of the HAS topology are exploited to develop the new algorithm. The simulation results show that the new algorithm greatly enhances the performance of revenue/cost (R/C) ratio while the HAS topology request arrives.
