我们提出了一种端到端网络切片的在线资源分配方案。我们的目标是为切片用户的整体时延提供保障，同时最大限度地降低移动网络运营商的运营成本。因此，我们基于优化问题开发我们的方案，在无线接入网络中共同执行带宽分配，并在核心网络中嵌入服务功能链。我们证明该方案具有多项式时间复杂度。我们的方案的性能是通过模拟进行评估的。结果清楚地表明，所提出的方案在用户数量方面是快速且高度可扩展的。
We propose an online resource allocation scheme for end-to-end network slices. Our aim is to provide guarantees for the overall delay of the slice users, while minimizing the operational costs of the mobile network operator. Hence, we develop our scheme based on an optimization problem, where we jointly perform bandwidth allocation in the radio access network, and service function chain embedding in the core network. We show that the scheme has polynomial time complexity. The performance of our scheme is evaluated via simulations. Results clearly show that the proposed scheme is fast and highly scalable with respect to the number of users.
