How do you do Point to Point Channel Bonding??

timjones · 05-26-2009, 03:21 PM

I have 4 point to point long distance 802.11g wireless links @ 6Mbps that I want to do packet level channel bonding on. What I am looking to do is to try to channel bond the connections together to get a sustained approx. 24 Mbps throughput.

Does anyone know if the Linux channel bonding driver supports point to point activity, or is it designed for load balancing only? Also, if this is not what I should be looking at, any ideas on where I should be researching this?? Any suggestions would be greatly appreciated...

Quote:

mode=0 (balance-rr)
Round-robin policy: Transmit packets in sequential order from the first available slave through the last. This mode provides load balancing and fault tolerance.

mode=1 (active-backup)
Active-backup policy: Only one slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The bond's MAC address is externally visible on only one port (network adapter) to avoid confusing the switch. This mode provides fault tolerance. The primary option affects the behavior of this mode.

mode=2 (balance-xor)
XOR policy: Transmit based on [(source MAC address XOR'd with destination MAC address) modulo slave count]. This selects the same slave for each destination MAC address. This mode provides load balancing and fault tolerance.

mode=3 (broadcast)
Broadcast policy: transmits everything on all slave interfaces. This mode provides fault tolerance.

mode=4 (802.3ad)
IEEE 802.3ad Dynamic link aggregation. Creates aggregation groups that share the same speed and duplex settings. Utilizes all slaves in the active aggregator according to the 802.3ad specification.

I'm considering this for a link here in a rural area by putting 3 USB wifi adapters at the horn of a large satellite dish at each end of the segment. Each ad-hoc connection would ideally be on a different channel 1, 6, and 11 for the least mutual interference.
