1 Motivation
With the ever-increasing number of new services and applications, demand has been continuously increasing for enhancing the capabilities of the next generation networks and evolving their infrastructure. The following aspects need to be considered with the Next Generation Network evolution (NGNe): ultra-high bandwidth, which is able to support bandwidth intensive data transmission; ultra-low latency guarantee; lossless transmission for industrial applications; network intelligence, which makes future evolved next generation networks to be highly automated.
Considering the above aspects and the evolution path of NGNs, the increasing possibilities of adoption of communication technologies (including but not limited to SDN, NFV, distributed ledger technologies and computing power network related technologies) with advanced information technologies are paving the way for evolution of NGNs, and are making available a large set of advanced capabilities for the support of innovative and promising services, applications and technologies in the various business domains and social communities.
Meanwhile, to satisfy the requirements and overcome potential challenges raised by NGNs evolution, it is appropriate to consider how to adopt emerging network technologies in order to provide the network with flexibility, agility and programmability and other advanced characteristics.
Furthermore, as NGN has established its position as an existing underlying network infrastructure for a large number of services and applications, it is critical to study how innovative services and applications meeting the industry demands can be realized by incremental enhancements of the capabilities of NGNs and evolved versions of NGNs such as network intelligence capability enhancement (NICE).
Last but not the least, the study of requirements and architecture for these realizations of innovative services, applications and technologies for NGNe requires that relevant NGNe specifications be maintained and updated.
