Foreword
Information and communication technologies
(ICTs) continue to change the way we do business
and go about our daily lives.
Consumers are beginning to enjoy a highly
immersive broadband experience. ICTs are at the
heart of innovation in almost every industry
sector, enabling businesses to capitalize on the

intelligence and efficiency introduced by
networked technologies.
In the near term, consumers expect to gain access
to new bandwidth-intensive services such as
advanced virtual reality applications. Industry
players expect to rollout automated driving,
collaborative robotics and remote medical
surgery.

Consumers and industry players are confident that
these advances are just around the corner. This
confidence is drawn from the IMT-2020 (5G)
vision, the prospect of an ICT environment trusted
to support the next major phase of ICT-enabled
innovation in the years following 2020.

ITU’s Radiocommunication Sector (ITU-R) is
coordinating the international standardization
and identification of spectrum for 5G mobile
development. ITU’s Standardization Sector (ITU-T)
is playing a similar convening role for the Chaesub Lee
technologies and architectures of the wireline
elements of 5G systems. Director of the ITU Telecommunication
Standardization Bureau
5G will make no compromises when it comes to
performance. Every application must be able to
perform to its full potential. This will demand
significant innovation in radio interfaces,
supported by ITU-R, as well as network
architectures and orchestration techniques,
supported by ITU-T.

This publication offers a compendium of the ITU
standards supporting the evolution of network
architectures and orchestration techniques.

The compendium takes stock of ITU standards
supporting software-defined networking, network
virtualization, information-centric-networking,
and advanced fronthaul and backhaul –
innovations expected to meet their great potential
in the 5G environment.
