. Scope Topics of Interest Call for Papers Committee Program . FED5G 2017 IEEE International Workshop on Federated Testbeds for NFV/SDN/5G: Experiences and Feedbacks . SCOPE of the Workshop All network and service providers are currently working to adopt the concepts of SDN/NfV and to bring to market new innovative products in this area. In this context a huge number of testbeds have been set up. They have been developed with several different and divergent goals: as a proof of concept; as a means to acquire know-how about the new technologies; as a first prototype to be consolidated into a product; or as an initial in-house platform to be consolidated and transformed into a production means. On the other side, a number of different companies (from SMEs to large Corporate) are keen to validate the technology and to exploit its advantages. Many testbed have been create locally and then opened up for interworking with other similar platforms. The interworking of the different pieces of the technologies are of fundamental importance in order to understand the feasibility and sustainability of the approach. Under this perspective, interworking, security and programmability will play a major role for the success of the SDN/NfV technologies. In order to substantiate the viability of the approach there is the need to integrate these separate infrastructures by interconnecting them and to prove the possibility to federate them on a larger scale testbed. This is an important prerequisite for the test and introduction of 5G and close fields like IoT. This workshop is meant to present first experiences and feedback from both experimenters but also from testbed infrastructure providers/operators. This includes dedicated use cases, architectures, setup and operating procedures, security aspects, programmability issues, etc. An important goal of this workshop is also to gather the community that is working towards the developments of the technologies and the platform and those people more interested in developing appealing applications on top of the platform. They represent two major development streams that have to work together in order to quicker move towards industrialization of the solutions.
