VTN has 2 components:
  * VTN coordinator (extern application)
  * VTN manager (Network Service Function)

{{:wiki:sdn:nethypervisor:vtn_how_it_works.png?600|}}

You can assign VTNs to Link paths. 
For instance VTN1,2,3 is assigned to Path1(Link1, Link2).
VTN4,5 is assigned to Path2(Link3)
===== VTN manager =====

The VTN manager:
  * creates the VTN networks,
  * map virtual interfaces to physical interfaces.

This division into slices of network is used to dynamically allocate brandwidth based on clients needs.
