论文摘要
本文旨在在VHCN（非常高容量网络）绩效目标的设置中提出一种可能的方法，该目标应该能够促进运营商有效的投资，同时提高最终用户的收益。为此，我们建议依靠一些特定的KPI（关键性能指标），尤其是吞吐量 - 即客户所感知的带宽 - 在应用程序层中有效，而不是物理层数据速率。在这方面，该论文强调了所感知的带宽与延迟严格相关。最重要的含义是，无法通过增加低级协议数据速率来满足未来设想的一些最苛刻的服务（例如，移动虚拟和增强现实，触觉互联网）。因此，对于通过边缘云计算（ECC）降低延迟的VHCN是强制性的先决条件。
This paper aims to propose one possible approach in the setting of VHCNs (Very High Capacity Networks) performance targets that should be capable of promoting efficient investments for operators and, at the same time, improving the benefits for end-users. To this aim, we suggest relying on some specific KPIs (Key Performance Indicators), especially throughput - i.e., the bandwidth as perceived by the customer - valid at the application layer, instead of the physical layer data-rate. In this regard, the paper underlines that the bandwidth perceived is strictly linked to the latency. The most important implication is that some of the most demanding services envisaged for the future (e.g., mobile virtual and augmented reality, tactile internet) cannot be met by merely increasing the low-level protocol data-rate. Therefore, for the VHCNs reducing latency through Edge Cloud Computing (ECC) is a mandatory pre-requisite.
