The rise of edge, cloud and in-network computing and the proliferation of Artificial Intelligence (AI) solution in networking are promoting the development of innovative applications like virtual/augmented reality, telepresence, autonomous systems, remotely controlled robotics and tactile applications, promising to revolutionize health-care, transportation, industry, agriculture, society and culture. To deploy such applications and to comply with their requirements, there is a need for new Internet paradigms including a Tactile Internet that combines ultra low latency with extremely high availability, reliability and security and has been the focus of both ITU and IETF/IRTF related initiatives.
Today’s Internet falls short when it comes to providing such requirements due to several design and implementation limitations. To overcome these there is a need to rethink and provide new architectures and protocols by efficiently harnessing recent Technological advances in terms of virtualization, network softwarization, NFV/SDN, Data plane programmability and even when they break the tenets of the current Internet. Such an architecture is embodied in the FlexNGIA Architecture (https://www.flexngia.net) that has the potential to enable novel network services and management schemes adapted to the requirements of future applications.
