IEEE 802.3ad
(Dynamic
Link
Aggregation)
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
(Adaptive
Transmit
Load
Balancing)
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.

Balance-alb
(Adaptive
Load
Balancing)
Balance-alb is similar to balance-tlb but also
attempts to redistribute incoming (receive load
balancing) for IPV4 traffic. This setup does not
require any special switch support or
configuration. The receive load balancing is
achieved by ARP negotiation sent by the local
system on their way out and overwrites the
source hardware address with the unique
hardware address of one of the Ethernet
interfaces in the bond such that different
peers use different hardware address for the
server. This mode provides load balancing and
fault tolerance.
