Okay, I was assuming the ISDN cards had some routing capability of thier own, like the external ISDN unit here. I've personally never met one of the internal beasts. > It would be interesting to see load balancing being standardized. > you can load balance ANY interface. let's say a device in kernel > to which you add multiple interfaces, which are multiple lines, > with the same routing info and kernel knows it can send packet > via any of them.. Any ideas how Linux and CISCO do 'em? I really do not know much about how FreeBSD handles IP at the kernel level, but it would seem to me something like that could be handled at the route layer... Instead of just disgarding packets it could check for an alternate route to the same destination. With a little extra accounting (keeping track of link speed and current percentage of use) it could be rather efficent at delivering packets by the best link at that particular moment.
