[Netkit.users] VDE & Netkit

Hello everybody.

I've seen that some people (in particular, Marco Fiscato and Antonio 
Anselmi) are interested in integrating Virtual Distributed Ethernet 
(VDE) inside Netkit.

I believe this would be a considerable improvement, which would 
introduce the opportunity to realize interesting scenarios that are not 
supported by the current Netkit architecture.

Introducing VDE support inside Netkit should not be a too invasive 
process: it's a matter of changing some scripts. Essentially, the target 
is to implement a new "advanced" switch whose interface is similar to 
the one of the standard uml_switch'es. Once this is done, using the new 
switch in the Netkit scripts is quite straightforward.

However, this could be a good chance to provide the swtiches with even 
more sophisticated features. Just think about the opportunity of 
configuring per-link delays, packet losses and similar stuff. Some 
development efforts in that directions have already been made (and will 
probably appear in the next release of Netkit), but without making use 
of VDE-aware solutions.

All of this does not collide with the development activity that is 
currently going on. We are working on testing a new kernel and a new 
suite of scripts, and we are going to check the labs as well. None of 
the above activities should impact the way VDE integration is supposed 
to take place.

VDE may hopefully be supported in one of the future releases of Netkit. 
Anyway, we do *not* plan to VDE-enable the next release.

Feel free to contact us for any further questions or support you should
