QoS for Fixed and Mobile Ultra-Broadband

10Conclusions

This book has focused on the quality of service for fixed and mobile ultra‐broadband, including technologies, regulation, and business aspects. The QoS has been mandatory for traditional telecommunication services such as telephony (voice) and television since the first half of the last century; however, with the convergence of telecommunication networks and services onto Internet technologies, QoS provision remains a significant challenge for all ICT services, not only for traditional ones. Therefore the ITU and other regional organizations (e.g. organizations of regulators) are involved in activities for QoS regulation in all regions of the world, besides the standardized approaches for QoS provisioning in Internet‐based environments which are done by different SDOs, including the ITU for global standardization and harmonization of telecommunications/ICTs, the IETF for Internet technologies from the network layer up to the application layer, the IEEE for Ethernet, WiFi, etc., 3GPP for broadband mobile networks (2G–5G and beyond), and others.

The introduction to this book, given with Chapter 1, aimed to provide information regarding the convergence of the telecom and Internet worlds which is being realized in the first two decades of the twenty‐first century, and which is expected to continue toward an all‐IP world. However, the traditional telecom world is based on strict end‐to‐end QoS provisioning, such as QoS in telephone networks for voice services (including ...
