Because the network is not like the internet, packet error correction and so on is done at lower layers, I mean... if there are some packets that are equivalent to the TCP SYNs, the 'SYN' timeout in our case is in minutes (because it is believed the host or a link is down or something else that could take longer time to resolve). This is bad, because connections will be established within some minutes... > Or alternatively use an internal queue of limited size to keep track of > those packages. This is probably the only solution I can think of right now, but I think poking a queue at regular, short intervals seems to me quite expensive, isn't it? Or perhaps there could be a netgraph node that handles the queue and connects to the userland daemon... but this could make things much more complicated... ? > > Joerg > _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
