The “It Just Is” Networking 2020 Vision
Future Network Stimulus:
Raised Expectations
The It-Just-Is Network:
• Connectivity happens
• Optimised delivery happens
• Services happen

A mishmash of Collisions and Synergies
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 selfevolving flexible IJI networking
