摘要 针对现有蜂窝系统无法满足触觉互联网延迟问题,提出一种基于软件定义网络的触觉互联网端到端系统。首先给出了触觉互联框架;然后提出一种基于软件定义网络(SDN)的多层触觉互联网端到端体系结构,该结构基于5G蜂窝系统,将硬件和软件分离,并提供API以便于系统的控制和管理,网络核心采用SDN并启用网络功能虚拟化(NFV),系统在多级云单元中使用移动边缘计算(MEC),减少通信过程中涉及中间节点的数量,从而减少延迟。实验结果表明该架构在5G高速率下能够得到毫秒级延迟,说明所提框架的可行性和有效性。

英文摘要 Aiming at the problems that the existing cellular system cannot meet tactile Internet delay, this paper proposed a software-defined tactile Internet end-to-end system. Firstly, the tactile interconnection framework is mainly composed of the primary domain. Then it proposed a multi-layered tactile Internet end-to-end architecture based on SDN, which was based on 5G cellular system, separated hardware and software, and provided API to control and manage the system. The network core adopted SDN and enabled NFV. The system used MEC in multi-level cloud units to effectively manage and established an efficient and flexible routing path between any two endpoints, thereby reducing delay. The experimental results show that the architecture can obtain millisecond delay at 5G high rate, which shows the feasibility and effectiveness of the proposed framework.
