The document summarizes several demos of a cloud network slicing platform called NECOS. It describes demos of multi-tenant network slicing with two example services, a scalability demo over Fed4Fire, lightweight slicing with VIM, and intelligent orchestration of slices using machine learning. The goals are to create two end-to-end cloud network slices between Brazil and Europe, one for an IoT service using the Dojot platform and one for a touristic CDN video service. It demonstrates the slices, services, and horizontal elasticity functionality.
