Online marketplaces are incredibly popular with customers around the globe selling products, also providing everyone as an online seller with a platform to reach a large, ready-to-buy products. Nonetheless, the issue is that it can be difficult to determine which one to trust as a seller. Especially in the world of 5G, where a marketplace is a mandatory component where developers can upload and verify their developed Network Services (NSs) or chained Virtual Network Functions (VNFs). Since those NSs are provisioned for a production environment, their consumers would need to trust the developer or the owner of that NS. To this end, in this paper we propose a smart distributed NFV Marketplace, in which we try to resolve security weaknesses related to the verification of the integrity of the developed VNFs and NSs. .

System Testing is the testing of a fully integrated software, as well as a series of different tests whose purpose is to exercise the full computer-based system. Software testing though, is an arduous and expensive activity. In the context of manual testing, any effort to reduce the test execution time and to increase defect findings is welcome. One of the biggest challenges in the upcoming 5G era is the validation and verification of VNFs and NSs, so that operators can be sure of their behavior in different execution environments. 5G technologies as well as SDNs are already introducing great challenges in the field service validation, testing and optimization of the underlying network. Considering the above, we propose a recommendation system acting as a Decision Support Mechanism integrated in an SDN environment. Its purpose is the proposition of tests to the software developers towards a stable NS ready to be deployed to the production environment.
