Improved Two-stage Virtual Network Mapping Algorithm
Lieguang Zeng · Jisuanji gongcheng · 2012
Based on the existing two-stage virtual network mapping algorithm,this paper proposes an improved algorithm to address the virtual network mapping problem by considering the impact of location constraints by combining the node resources migration and link splitting.Simulation results show that compared with the existing algorithm,the acceptance ratio of virtual network requests enhances by about 10%,the long-time average revenue increases by about 15%,and the benefit-cost ratio increase by about 12%.
