Hi Dominique,=20

As you probably saw in the documentation in trafficgen.ml, a traffic=20
generator does not integrate the notion of destination - it only generates=
=20
the time intervals between successive packets.=20

This could possibly be changed but my intent was that one trafficgen would=
=20
model/represent one session between a pair of nodes (say a TCP dialog=20
between two nodes, or a file transfer, or more generally some=20
statistical process). I hadn't really foreseen generating a traffic=20
pattern like what you need, but that's a perfectly reasonable one.

So I'll try to implement this over the weekend and let you know as soon as=
=20
it's done.

PS. Btw to generate traffic to multiple nodes with the current version,=20
one way would be to install a trafficgen for each destination on each node.=
 But this is not very=20
scalable obviously (and in fact looking at node.mli comments not really=20
working right now).=20

PPS. If you need to make this work urgently, the simplest way is to create=
=20
your own function that directly calls #originate_app_pkt (see node.mli) on=
=20
node objects according to the traffic pattern you need
