In 2020, the new 5G mobile network arrives. There are many expectations on benefits and the first experiments have already started.
The new network architecture, which initially is taking place side by side with existing ones, has being designed to offer multiple layers (Slicing) on the same infrastructure, thus allowing services with different qualities. Within each layer, it is possible to differentiate aspects such as bandwidth, processing capacity (intensive), quantity of data to collect (Collected Data), security etc. These parameters can be dynamically managed using the NFV and SDN paradigms.
In the last years, the technological evolution of servers and storage systems encourages the abandonment of embedded systems and the adoption of the NFV technology that extends Cloud Computing from IT context to Telco.
At the same time, for improving the infrastructure cost saving, operators tend to reduce the manpower to manage the networks not only increasing outsourcing but also designing new networks with automated services configuration and management, leveraging new technologies based on Self Organizing Network (SON) and Software Defined Network (SDN).
The 5G network, evolving a requirement of 4G networks already, distinguishes the control data plan from user data plan. In addition, to improve network performance, the architecture is designed to also allow high processing at the edge of the network, integrating the concepts of Multi-Access Edge Computing (MEC) introduced by ETSI. The placement of the MEC in 5G networks is expected within the Data Centers that will host applications for management of the radio part (virtual Radio Access Network).
In conclusion, 5G users may enjoy a level of performance and a set of features that best suit their needs.
