The “It Just Is” Networking 2020 Vision
Future Network Stimulus:
A mishmash of Collisions and Synergies
The It-Just-Is Network:• Connectivity happens
• Optimised delivery happens
• Services happen
Raised Expectations

Goals and Aims
The Goal: Provide future networks with design methodologies enabling technologies that promote
flexible, agile, dynamic and self-evolving networking
A Network capable of coping with unforeseen demands
The Aim: identify those key socio-economic parameters that impact
future network design Use these parameters to help identify suitable technologies to
promote desired future network properties
Develop a network design methodology that promotes self-evolving flexible IJI networking
