Introduction xxi
I.4. Conclusion
In conclusion, the world of networks is changing greatly, for the
reasons listed above. It is changing more quickly than might have
been expected a few years ago. One initial proposition was put
forward, but failed: starting again from scratch. This is known as the
“Clean Slate Approach”: eliminating everything and starting again
from nothing. Unfortunately, no concrete proposition has been
adopted, and the transfer of IP packets continues to be the solution for
data transport. However, in the numerous propositions, virtualization
and the Cloud are the two main avenues which are widely used today
and upon which this book focuses.
