Questions tagged [bonding]

"bonding" is the Linux-term for link aggregation.

Cisco terminiolgy is "etherchannel", other vendors may talk about "trunking".

The idea is to use several pyhsical lines in the same (sub)network or VLAN and load-balance the traffic across these lines.

To make it work both "ends" need to use the same LB-mode.

How do I bond ADSL lines for VOIP?

We're using G711a as a codec, and I wanted to bond ADSL lines to give me the maximum possible upstream. I know that there can be issues of packet re-ordering etc; what is the 'right' way to do this? (other than getting a leased line).
