In physics, superfluidity is a state in which matter behaves like a fluid with zero viscosity. The vision of superfluid networking corresponds to the ability to decompose services into network functions to be deployed on-the-fly, run them anywhere in the network (core, aggregation, edge) and shift them transparently to different locations and heterogeneous execution environments. Superfluid networking tackles crucial shortcomings in today’s networks like long provisioning times, with wasteful over-provisioning used to meet variable demand and reliance on rigid and cost-ineffective hardware devices. The 5G System architecture can be deployed using techniques like Network Function Virtualization (NFV) that potentially enable the realization of superfluid networking. In this talk, we discuss the state of the art of NFV models and infrastructures for 5G and illustrate the path toward superfluid networking, considering the results of the Superfluidity research project (funded by EU in the H2020 framework).
