At the end of May 2017, the technical review of the project in its intermediate phase performed by EU authorities took place at 5TONIC, Madrid. 5TONIC is part of the 5GEx sandbox, a distributed testbed composed of 14 sites — including those of 4 European operators — that is used by the 5GEx project to validate the solutions developed and assess their performance. During the review, 5GEx researchers presented their contributions on multi-domain and multi- provider orchestration of resources and services, including their latest contributions to the main standard development organizations (SDOs): ETSI NFV, IETF/IRTF, 3GPP and ONF.
One of the key outcomes of the project so far is the reference implementation of some of the features of the 5GEx architecture. Using this implementation, different demos were showcased. One of them showed the benefits of moving the intelligence required to operate a couple of robots to a cloud infrastructure running at the edge of the network. This provides a flexibility key for the so-called Industry 4.0: the industry of the future.
