针对虚拟网络可靠映射问题,引入虚拟网络可生存约束条件,确保在底层网络单节点失效情况下,被映射虚拟网络剩余部分仍保持连通,最大程度确保虚拟网络的完整性和服务的连续性。以最小化底层网络映射开销为目标函数,建立虚拟网络可靠映射的整数线性规划模型,提出一种虚拟网络可生存的启发式可靠映射算法RHM-SVN并进行求解。实验结果表明,该算法能够有效降低资源平均利用率,提高映射成功率、底层网络平均收益和虚拟网络恢复成功率。
For reliable virtual network mapping problem
virtual network survivability constraints are introduced to ensure that the rest of the mapped virtual network remains connected under a single node failure condition in the substrate network
which makes sure the completeness of the virtual network and continuity of services.In order to reduce cost of the substrate network
the reliable heuristic mapping problem is considered as an integer linear programming model and a reliable heuristic mapping method for survivable virtual network is proposed to solve the problem.The simulation results show that average usage of links is reduced and the success rate
average revenue of mapping
recovery success rate of virtual network are increased compared with the existing reliable mapping algorithms.
