论文摘要
对于非常高容量的网络（VHC），主要目标是提高最终用户体验的质量。这意味着应用程序要求的关键绩效指标（KPI）。应用程序级别的关键性能指标是吞吐量，下载时间，往返时间和视频延迟。它们取决于服务器和最终用户设备之间的端到端连接。对于VHC网络，电信运营商必须提供所需的应用质量。此外，它们必须符合经济可持续性的目标。如今，电信运营商很少实现上述目标，这主要是由于不考虑应用程序的端到端KPI的推动力增加了访问网络的比特率。本文的主要贡献涉及部署框架的定义，以解决VHC网络的性能和成本问题。我们展示了需要集中精力的三个动作。首先，通过视频压缩来限制位率。其次，包含通过人工智能算法进行线路稳定的数据包丢失率。第三，使用Edge-Cloud Computing减少延迟（即往返时间）。这些措施的一致和逐步应用可以使电信公司摆脱访问网络的超宽带“陷阱”，如论文中所定义的那样。我们建议对带宽利用率的端到端优化进行研究。这导致最终用户的表现更好。它还允许电信运营商创建新的业务模型并以可持续成本获得新的收入流。举一个明确的例子，我们描述了如何实现移动虚拟和增强现实，这是最具挑战性的未来服务之一。
For very high capacity networks (VHC), the main objective is to improve the quality of the end-user experience. This implies compliance with key performance indicators (KPIs) required by applications. Key performance indicators at the application level are throughput, download time, round trip time, and video delay. They depend on the end-to-end connection between the server and the end-user device. For VHC networks, Telco operators must provide the required application quality. Moreover, they must meet the objectives of economic sustainability. Today, Telco operators rarely achieve the above objectives, mainly due to the push to increase the bit-rate of access networks without considering the end-to-end KPIs of the applications. The main contribution of this paper concerns the definition of a deployment framework to address performance and cost issues for VHC networks. We show three actions on which it is necessary to focus. First, limiting bit-rate through video compression. Second, contain the rate of packet loss through artificial intelligence algorithms for line stabilization. Third, reduce latency (i.e., round-trip time) with edge-cloud computing. The concerted and gradual application of these measures can allow a Telco to get out of the ultra-broadband "trap" of the access network, as defined in the paper. We propose to work on end-to-end optimization of the bandwidth utilization ratio. This leads to a better performance experienced by the end-user. It also allows a Telco operator to create new business models and obtain new revenue streams at a sustainable cost. To give a clear example, we describe how to realize mobile virtual and augmented reality, which is one of the most challenging future services.
