Network Applications: Opening up 5G and beyond networks

As part of the 5G-PPP Initiative, the Software Network Working Group prepared this white paper to demystify the concept of the Network Applications. In fact, the Network Application ecosystem is more than the introduction of new vertical applications that have interaction capabilities. It refers to the need for a separate middleware layer to simplify the implementation and deployment of vertical systems on a large scale. Specifically, third parties or network operators can contribute to Network Applications, depending on the level of interaction and trust. Different implementations have been conducted by the different projects considering different API types and different level of trust between the verticals and the owner of 5G platforms. In this paper, the different approaches considered by the projects are summarized.
