Part 1: Networks and System ArchitectureInternational audienceToday, TCP is the go-to protocol for building resilient communication channels on the Internet. Without much overstatement, it can be said that it runs the majority of communication on the planet. Its success only highlights the fact that it also has some drawbacks, of which one of the oldest ones is the inability to hand over running connections between participating hosts. This paper introduces a method that relies on the advantages of Software Defined Networks to overcome this limitation

This article presents a comparison of main characteristics of the Next Generation Networks (NGN) and Future Generation Internet (FGI). 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’s FGI and telco’s NGN are not that different after all. The convergence of the two approaches therefore seems the only logical way forward
