The network infrastructures we use today, in particular the Internet, rely on an architectural model which resulted from guiding principles laid down in the mid 70's. At that time, mobility, wireless access, predictable quality of service, scalability to trillions of connected devices, security were not considered as stringent requirements. Over the past two years, active research has been conducted to revisit the network architecture, to determine whether it can be changed to align with current and better requirements. This series of lecture will expose the state of the art of this work and will discuss status and future trends in network architectures.
