The technological evolution centered on the concepts of Software Defined Networks (SDN), Network Functions Virtualization (NFV), Cloud Computing, Internet of Things (IoT), and, more recently, the next generation of mobile telecommunications networks, known as 5G&B, has caused a significant impact on the Internet. This impact comes not only from creating new technologies, communication protocols, security solutions, energy efficiency mechanisms, and others but also from the need to jointly operate this plethora of innovations with the legacy of the Internet. As a result, several experimentation environments with different scopes have emerged in Brazil, targeting the research of different subsets of technologies, among them: FIBRE, experimentation of alternative SDN architectures to the current Internet; FUTEBOL, experimentation in telecommunications networks involving optical and wireless communications; CloudNEXT, experimentation on cloud computing and bare-metal provisioning; FIWARE, future Internet-Based applications based on Internet of Things (IoT), Big Data and Cloud Computing; 5GINFIRE, experimentation in 5G networks, based on NFV and cloud usage; and finally NECOS, focused on the creation of slices that encompass different clouds with distributed resources.

In this scenario, the main objective of the SFI2 project is to create a solution for providing advanced network experimentation and allocating resources by slicing these multi-domain and multi-technology experimentation networks (testbeds). SFI2 aims to create a sliced virtual network with minimum configuration effort based on the intelligent orchestration of multi-domain resources and to offer Slice-as-a-Service (SlaaS) capabilities for future Internet developers.
