摘　　要：下一代网络采用基于SDN方法的NS技术要求NGN必须既能承载重计算负荷又能保障高质量端到端业务传输质量,给NGN的硬件计算资源池以及计算服务的接纳与调度带来巨大的挑战。首先分析了NS分级接纳调度的系统模型,证明了分级接纳调度技术的可行性,并提出了一种基于固定配额的分级VM/NS接纳调度算法,通过实时修正并行多种业务计算片段序列的效用,以分级接纳调度的形式利用硬件资源池,从而达到最大化整体效用的目的。仿真结果表明,提出的分级VM/NS接纳调度算法对NGN硬件资源池的利用率可以稳定地接近于100%状态,同时满足通过接纳进入计算服务的所有业务的QoS要求。The next generation network uses the NS technology based on the SDN method requiring the NGN to carry both heavy calculation load and high quality of end-to-end service transmission, which brings huge computation and scheduling of the hardware computing resource pool and computing service of the NGN challenge. This paper first analyzed the system model of NS hierarchical admission scheduling, proved the feasibility of hierarchical admission scheduling technology, and proposed a multi-level VM/NS admission scheduling algorithm based on fixed quota. By real-time correction of multiple business computing fragment sequences, the hardware resources pool was used with the form of hierarchical acceptance scheduling, so as to achieve the purpose of maximizing the overall utility. The simulation results show that the utilization rate of the multi-level VM/NS admission scheduling algorithm proposed in this paper can be close to the 100% state of the NGN hardware resource pool and meet the QoS requirements of all services entering the computing service.
