Hello,
I'm not sure if this is the appropriate list, so sorry and please redir-me.
:-)
My question:
Last week when I was proving howto make a twist in th EQL driver to achieve
what my box, with multiple eth0 and ppp(0-n)s, can do a _elegant_ transfer
from one dev to another (or any) of the send buffer, I can't find the
appropiate way to do.
In other words, I want a router with on demand multiple backups lines to
transmit (receive is not a problem yet), when occurs some (or all) of the
follows:
a) the primary (or the current) dev was down, so I need to startup a
secondary (next configured) dev.
b) the primary (or the currents ) is too busy (throttled in NAPI I guess) so
a second (or third, fourth, ...) path (dev) is requiered (ON-DEMAND) to
satisfy the demand. Those new links must dissapears when no longer neededs
(auto-shutdown)
c) all this stuffs must occurs tansparently to user-level apps, so no packets
will be dropped at all while the kernel is traying to figure what dev will be
used in the next loop.
My guess:
A combination between a kernel module (already begun one) and userland server
to up/down the interfaces.
Anybody, please, send me a clue about this?
Another way to do that?
PD: sorry about my english, is not my mother languaje ;-P
