- message aggregation into single packet, so less headers
- jitter, reduction of collisions
Currently we don't have selective multicast forwarding. BMF is broadcasting.
Pseudo-broadcast to few neighbors with high rate unicast would have better performance and reliability than flooding.
Message flooding is more efficient than multicast in the mentioned examples. Maybe not always.
I would like integration of mdns, p2pd and bmf in a single plugin, where a packet filter engine can direct packet processing, e.g. BMF style *or* distribution with messages. Could / should be a separate deamon, as discussed some time ago. Something for after v2.
