论文摘要
网络社区继续创建新技术并更新现有技术,以提高数据网络的质量,可靠性和“可卸载性”。但是,每当互联网服务提供商都试图生产“可租赁性”并明确出售以作为最佳服务的优质服务而出售,他们要么无法克服网络中立性问题,要么努力获得市场吸引力。在本文中,我们仅关注那些网络协议,技术或标准,其目标是为公共网络上的付费客户提供量身定制的连接,并将其称为差异化QoS(D-QOS)标准。本文做出了两个贡献。首先,它探讨了D-QOS标准的技术经济市场轨迹,以了解决定成功的因素。在这样做的过程中,我们承认,尽管其基本技术属性存在广泛的差异和差异,但所有D-QOS标准的期望和目标是,它们将用于为客户准备好付款的保证连接。因此,我们考虑2/3层技术(例如,ATM,框架继电器,MPL),信号技术(例如RSVP),数据包标记(例如IP TOS,DIFFSERV,WME,WME,QCI)和端到端分离解决方案(例如,线路,网络,网络,单个slice cohort suse cohort and cohort and cohort cohort)其次,通过探索与5G网络切片的相似之处,我们认为,尽管它与其他D-QOS标准存在固有的技术差异,但网络切片的商业性能最终可能与以前的D-QOS标准相似。因此,我们试图从以前的D-QOS尝试中学习课程,并建议以企业为重点的5G切片在单个服务提供商的域内运行,并且具有约束力的服务水平协议,将在短期/中期获得最大的成功机会。
The networking community continues to create new technologies and update existing ones to improve the quality, reliability, and "tailorability" of data networks. However, whenever Internet service providers attempt to productize "tailorability" and sell it explicitly to end customers as a premium service over best effort connectivity, they either fail to overcome net neutrality concerns or struggle to gain market traction. For this article, we focus only on those networking protocols, technologies, or standards whose goal is to offer tailored connectivity to paying customers on a public network and refer to them as differentiated QoS (D-QoS) standards. This article makes two contributions. First, it explores the techno-economic market trajectory of D-QoS standards to understand the factors that determine success. In doing this, we acknowledge that while there is wide variation and dissimilarity in their underlying technical properties, the expectation and goal for all D-QoS standards is that they will be used to provide guaranteed connection for which customers could be prepared to pay. As such, we consider Layer 2/3 technologies (e.g., ATM, frame relay, MPLS), signaling technologies (e.g., RSVP), data packet markers (e.g., IP ToS, DiffServ, WME, QCI), and end-to-end separation solutions (e.g., leased lines, network slicing) as a single cohort and analyze them together. Second, by exploring the parallels with 5G network slicing, we argue that despite its inherent technical differences with other D-QoS standards, the commercial performance of network slicing may end up resembling that of previous D-QoS standards. Consequently, we seek to learn lessons from previous D-QoS attempts and suggest that enterprise-focused 5G slices, running within a single service provider's domain and with binding service level agreements, will have the highest chance of success in the short/medium term.
