Net.fd and broute

Is it possible to broute with a Net.fd Network driver, or
is this something only native Ethernet drivers can do?

brouting is done by Net, not the driver. Theoretically, I think
you could probably do it over anything, including a Net.fd link,
but I don’t like to think about what the latencies would be like,
and it might not be particularly stable.

Hmmmm, this is not the answer I was expecting. I was told
that you cannot broute of Arcnet, which does fit the
description of “anything”. As far a latencies, I think that
if you already accept the latency in a serial QNET link,
then having broute support would only enhance the
functionality, assuming you don’t overuse the link.

In any case, thank you for your answer.

Perhaps this one is :slight_smile:

It definitly works! … with the same restrictions that apply to
the other IEEE 802 compatible NICs.

In words: you cannot rely on the qnx_net_alive() base functions,
as long as not all nameloc’s in the net can see all nodes each.
Nevertheless the base functions Send()/Receive() work fine in
all constellations.
