What's the difference between 802.3ad, active-backup, balance-tlb/rr/xor and broadcast?
Thank you.
balance-rr
Transmissions are received and sent out sequentially on each bonded slave interface. This mode provides fault tolerance and load balancing.
active-backup
Only one slave in the bond is active. Another bonded slave interface is only used if the active bonded slave interface fails. This mode provides fault tolerance.
balance-xor
Transmission is based on the following equation: [(the source MAC address XOR'd with the destination MAC address) modulo (slave count)]. This selects the same slave for each destination MAC address. This mode provides fault tolerance and load balancing.
broadcast
Transmits everything on all slave interfaces. This mode provides fault tolerance.
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. Requires a switch that supports IEEE 802.3ad Dynamic link aggregation.
balance-tlb
Channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave. This mode provides fault tolerance and load balancing.
