This document reports all the activities related to the design and prototyping of a virtualised Mobile/Multi-access Edge Computing (MEC) infrastructure segment as part of the SliceNet end-to-end slicing-friendly infrastructure. The design and prototyping ensures that the SliceNet MEC infrastructure is fully compliant with the ETSI MEC architecture and offers enablers for network slicing. SliceNet MEC architecture comprises a low-latency MEC platform, and a programmable Data Plane, multi-tenanted infrastructure, with Management Plane functionality support taken into account. Furthermore, representative MEC applications are described to show the practical use cases of the SliceNet MEC architecture.
