Q16. You have a trainee at your company and you are mentoring him. The trainee came across the term “Network Slicing”. He asks you what is “Network Slicing” and why do we need it?

Network Slicing is just like the OSI model. It is the division of the network into layers horizontally from the physical to the application. It is needed to specify which layer a service resides.

Network Slicing is a technology that allows the network to serve applications with different sets of requirements in terms of latency, reliability, capacity, density, and such. Every application has a set of requirements different from others. With network slicing, we give every application what it needs from the network.

Network Slicing is an end-to-end “virtual private service”, extending across access, transport, core, and cloud. It is a general term used to define in which piece of the network we are.

Network slicing is a new technology to divide the network among users. It is needed for confidentiality purposes.

Q17. Imagine that you are defining the 5G network requirements for the Industrial Automation of a port, what is the set of 5G technology enablers and horizontal applications that makes sense?
