Hello lists,
in order to evaluate the latency penalty induced by mobile IPv6,
i need some way to simulate different latencies between two nodes
in a laboratory environment.
Is it possible at the moment to shape IPv6 traffic with KAME SNAP
20050919
and FreeBSD 5.4-RELEASE?
If not, is there some other way to enforce latencies on an interface?
thnx,
/folkert
