摘要
SPN的发展为5G传输网的应用提供了一种全新的方式,它能够以更高的质量、更快的速度和更广阔的带宽实现各种业务的传输。然而在“5G+”车联网领域,仍然存在许多挑战。本文通过对SPN试验网的设计、构建,深入研究了SPN系统的切片功能与业务承载能力,经研究发现,切片功能管控面可以有效降低业务开通、维护的复杂程度,转发面还可通过相应技术发挥车联网业务的带宽调度与隔离等功能,从而大幅提高网络的安全性和可靠性。
The development of SPN provides a new way for the application of 5G transmission network,which can realize the transmission of various services with higher quality,faster speed and broader bandwidth.However,in the field of 5G+Internet of Vehicles,there are still many challenges.Through the design and construction of the SPN test network,this paper deeply studies the slicing function and service carrying capacity of the SPN system.The research finds that,the slicing function control plane can effectively reduce the complexity of service provisioning and maintenance,and the forwarding plane can also play the functions of bandwidth scheduling and isolation of Internet of Vehicles services through corresponding technologies,so as to greatly improve the security and reliability of the network.
