Abstract:At present, virtual network mapping algorithms obtain suboptimal solution based on constraint condition, they still have the issues of solving mapping equations complicatedly, high computation cost and lack of specific path selection method. To address these issues, a novel virtual network mapping algorithm called Valiant Load-Balancing-Virtual Network Embedding (VLB-VNE) is proposed. VLB-VNE divides the nodes of core/backbone network into several regions. And the region has full mesh logical topological structure and valiant load-balancing routing scheme. VLB-VNE is based on greedy iterative algorithm in the region level. Theoretical analysis and simulation results prove that: VLB-VNE achieves a rational and mapping easily practical network, combines nodes and links mapping, reduces computation cost and possesses optimality of valiant load-balancing network in throughput delay and routing complexity.
