摘　　要：针对虚拟网络切片差异化资源分配不均、资源分配成本较高的问题,引入信任感知安全约束,并结合差异化资源分配业务关键通信约束条件,确定全部业务虚拟网络切片租赁花费最低为目标函数,构建信任感知的虚拟网络切片差异化资源分配算法。通过凸优化理论的子梯度算法求解,获取最终的虚拟网络切片差异化资源分配结果。结果表明,采用该算法获得的虚拟网络请求接收率和物理网络映射收益较高,满足了切片租赁的总花费目标。该算法能够实现虚拟网络切片差异化资源分配。In response to the problems of uneven resource allocation and high resource allocation costs in virtual network slicing,a mathematical model of differentiated resource allocation for virtual network slicing,based on trust perception,is constructed by introducing trust perception security constraints and combining critical communication constraints for differentiated resource allocation business.The objective function is to determine the minimum cost of leasing all business virtual network slices,and this is used to construct a trust perception-based mathematical model for differentiated resource allocation in virtual network slicing.The subgradient algorithm of convex optimization theory is used to solve the construction model,and the final virtual network slice differentiated resource allocation result is obtained.The experimental results show that the virtual network request receiving rate and the physical network mapping income obtained by the mathematical model are high,and meet the total cost target of slice lease.It is proved that the mathematical model can realize the differentiated resource allocation of virtual network slices.
