Does Nokia Corroborate with 5G as "Application Defined networking".

I happened to be stuck with a Nokia presentation on 5G QoS nuances and requirement for network slicing and latency. The presentation was available in slide share, shared by Eiko Seidel ( My unknown friend from NOMOR).

I being an strong advocate for 5G networks as "application defined network", since the beginning, found excited here and wanted to share some of the salient aspect of the presentation, which corroborate my concept.

In the very first screen the presentation take the following norm while talking about the 5G QoS.

QoS being taken in 5G as optimization of individual application sessions. Looking at the internet landscape, it is found that diversity and versatility of applications require real time and dynamic management for QoS.

Also that, operator loos insight into real time customer experience per application, and ability to manage it. Although it is need to be bore by application developers, devices vendors and content owner too, but operator's are taken as the real respondents.

Also the QoS frame work in LTE is static and does not handle the dynamic aspects of application and not optimize the network in line of application efficiency. The bearer definitions are limited and provide an scalable framework which is dealt differently at different network level, like QoS parameters set at the core has to be catered by the RAN in its own way of implementation. This does not provide a right or efficient mapping for each and every application.

Now looking at how nokia set the high level principle to define 5G QoS framework.

And this is defining the new architecture at high level as per nokia too.

This about real time Application awareness at core and RAN both and dynamically apply the QoS. This will require real time analysis and machine learning principle as well to do the job coherent and efficient.

Interesting to note that nokia clubbed this QoS presentation with network slicing too. As, what I think, for the ease of implementation of the concept, as the underlying network requirements for providing the required coherency, efficiency and flexibility.

Network slicing will also bring network multiplexing for the efficient delivery of application and you build your network based on the application requirement. A RAN may connect to differnet core and vice-a-versa. These set of end to end networks are really application defined.

That is why, I said earlier, 5G is about Application Defined Networking.

You may find the presentation from nokia either from slide share directly or through my previous blog.
