The aim is to discuss and compare two approaches to Future Networks (FN) and services: the evolution of NGN, and the revolutionary approach of a new FGI. We present both frameworks from the services point of view as they are delivered to the end-user, as well as from the architectural point of view. We compare selected properties of both approaches to explain commonalities and differences. Their challenges are similar: managing the quality of experience, mobility, security, scalability and providing openness to applications. Based on this comparison, we evaluate possible areas for future convergence in the approach of the two architectures to the Future Network concept. Our analysis shows that despite their different backgrounds, the internet\u2019s FGI and telco\u2019s NGN are not that different after all. The convergence of the two approaches therefore seems the only logical way forward.<\/jats:p>","DOI":"10.3390\/fi3010067","type":"journal-article","created":{"date-parts":[[2011,3,6]],"date-time":"2011-03-06T18:54:40Z","timestamp":1299437680000},"page":"67-86","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Evolution of the Converged NGN Service Platforms Towards Future Networks"],"prefix":"10.3390","volume":"3","author":[{"given":"Eugen","family":"Mik\u00f3czy","sequence":"first","affiliation":[{"name":"Slovak University of Technology in Bratislava, Ilkovi\u010dova 3, 812 19 Bratislava, Slovakia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1811-1580","authenticated-orcid":false,"given":"Ivan","family":"Kotuliak","sequence":"additional","affiliation":[{"name":"Slovak University of Technology in Bratislava, Ilkovi\u010dova 3, 812 19 Bratislava, Slovakia"}]},{"given":"Oskar van","family":"Deventer","sequence":"additional","affiliation":[{"name":"TNO, P.O.
