摘要: 作为5G及未来通信网络的关键使能技术,网络切片凭借其在垂直行业定制、服务质量保障、灵活性、可靠性等方面的潜在优势,获得了运营商和学术界的广泛关注和认可。目前,已有不少相关组织以专题报告的形式呈现了其对网络切片的理解及未来发展设想。但是,这些报告的侧重点各有不同且相关术语尚未规范统一,此类问题的存在给研究人员理解网络切片带来了诸多阻碍。为便于研究人员把握网络切片的发展脉络、技术架构,以及管理编排等具体内容,文中对相关研究进行了综述。首先介绍了网络切片的产生背景、具体含义以及功能特性。其次,针对端到端网络切片的实现,分别就接入网切片、承载网切片以及核心网切片这3方面的内容,对近年来的网络架构发展、技术突破以及标准化成果展开了论述。而后就网络切片管理与编排的具体内容进行了介绍与分析,并依据切片场景的不同对相关研究进行了分类梳理与比较。最后,结合网络切片的发展需求和现实困境,指出了目前研究所面临的一些开放性挑战。
