Towards Softwarization of Mobile Networks and Content Delivery<br />
Platforms<br />
Today we talked about 5G and its requirements. I did my bachelor thesis related to requirements of 5G so<br />
today’s topic was very familiar to me. This also made the lecture easy to follow since most of the topics<br />
were familiar to me.<br />
A. Lesson learned<br />
Today I learnt about network softwarization which was a new concept for me. It is an overall<br />
transformation trend and the idea is to make the network more flexible and simple by changing the trend<br />
of designing, implementing and deploying NW equipment and components. It can be achieved by SW<br />
programming.<br />
Its main task is to isolate and separate different network slices, how and what type of resource and NF<br />
sharing can be used between NW slices and how to enable multiple services from slices at the same time to<br />
user.<br />
Slicing was another new concept for me. It enables a network operator to provide dedicated virtual<br />
networks with functionality specific to the server or to user over common network infrastructure. So,<br />
slicing allows multiple virtual networks to be created on top of a common shared physical infrastructure.<br />
Network is not always optimal to different services so slicing will be very important in the future. For<br />
example, in 5G, a single physical network will be sliced into multiple virtual networks that can support<br />
different radio access networks (RANS), or different service types running across a single RAN. This will<br />
make 5G more flexible and agile compared to older mobile technologies. There will be more and more<br />
services in the future so this kind of “slicing technology” will be vital to make these services to work.<br />
B. Problems and open issues<br />
There were not many things that I did not understand. EPCaaS Architecture Options was one thing that<br />
went over my head. I tried to google it but without a success. There were a few figures which tried to<br />
explain it but I did not understand the idea of this concept.<br />
C. Relevance<br />
5G will be a huge thing for us. It will increase data rates, decrease latency and bring us more services since<br />
it will be more diverse and it can handle more traffic than technologies that we have now. 5G has also very<br />
important role on my studies since it will be the next “big thing” in communication engineering field. I did<br />
my bachelor thesis about 5G and its physical layer and we have studied 5G technology in our courses so I<br />
am able to apply easily this knowledge to my studies.<br />
