Round-Robin mode is good for general purpose load
balancing between two Ethernet interfaces. This mode
transmits packets in sequential order from the first
available slave through the last. Balance-rr provides load
balancing and fault tolerance.
Active Backup uses only one Ethernet interface. It
switches to the second Ethernet interface if the first
Ethernet interface does not work properly. Only one
interface in the bond is active. The bond's MAC address
is only visible externally on one port (network adapter)
to avoid confusing the switch. Active Backup mode
provides fault tolerance.
Balance XOR balances traffic by splitting up outgoing
packets between the Ethernet interfaces, using the same
one for each specific destination when possible. It
transmits based on the selected transmit hash policy.
The default policy is a simple slave count operating on
Layer 2 where the source MAC address is coupled with
destination MAC address. Alternate transmit policies may
be selected via the xmit_hash_policy option. Balance
XOR mode provides load balancing and fault tolerance.
Broadcast sends traffic on both network interfaces. This
mode provides fault tolerance.
Dynamic Link Aggregation uses a complex algorithm to
aggregate adapters by speed and duplex settings. It
utilizes all slaves in the active aggregator according to
the 802.3ad specification. Dynamic Link Aggregation
mode provides load balancing and fault tolerance but
requires a switch that supports IEEE 802.3ad with LACP
mode properly configured.
Balance-tlb uses channel bonding that does not require
any special switch. The outgoing traffic is distributed
according to the current load on each Ethernet interface
(computed relative to the speed). Incoming traffic is
received by the current Ethernet interface. If the
receiving Ethernet interface fails, the other slave takes
over the MAC address of the failed receiving slave.
Balance-tlb mode provides load balancing and fault
tolerance.
