Отказоустойчивость. Как балансировать с 2-мя каналами

[Okami]

Есть сервер и на нем 2 ethernet карточки, соединенные к разным каналам связи ( одна радио 10 мбит, другая - оптика 100 Мбит ). Как сделать, чтобы при пропадании связи в оптическом канале, сервер переключался на запасной канал автоматически? Можно ли также балансировать по портам, скажем запросы по 80-му пустить по радио, а файловый доступ (netbios) - по оптике ?
Есть идеи?

Или это Bonding driver support (BONDING) Say 'Y' or 'M' if you wish to be able to 'bond' multiple Ethernet Channels together. This is called 'Etherchannel' by Cisco, 'Trunking' by Sun, 802.3ad by the IEEE, and 'Bonding' in Linux. The driver supports multiple bonding modes to allow for both high perfomance and high availability operation. Refer to for more information. To compile this driver as a module, choose M here: the module will be called bonding. Или это - EQL (serial line load balancing) support (EQUALIZER) If you have two serial connections to some other computer (this usually requires two modems and two telephone lines) and you use SLIP (the protocol for sending Internet traffic over telephone lines) or PPP (a better SLIP) on them, you can make them behave like one double speed connection using this driver. Naturally, this has to be supported at the other end as well, either with a similar EQL Linux driver or with a Livingston Portmaster 2e. Say Y if you want this and read . You may also want to read section 6.2 of the NET-3-HOWTO, available from . To compile this driver as a module, choose M here: the module will be called eql. If unsure, say N.

Спасибо, земляк! Попробуем...

Bonding driver
В FC4 драйвер есть
