MEC Placement Problem in Protected 5G Networks

This paper summarizes the thesis ”MEC Placement Problem in Protected 5G Networks”, which tackles the question of where to position Multi-access edge computing nodes (MECs) in 5G networks to achieve stringent 5G requirements at a minimum cost.The thesis formulated the MEC placement problem with traditional protection schemes to provide redundancy in the event of MEC failures, and proposed a new scheme called ’enhanced shared protection 1 : N : K’. The work investigated the impact on the costs of new variations of the MEC placement approaches considering different distributions of VNFs forming SFC requests. The results indicate that the enhanced protection scheme is cost-effective, and the VNF distribution impacts significantly on the cost.
