High Availability ✔

✔

HA goal is to provide the maximum availability of network connectivity HA configurations have redundant or backup network devices or (and) links between the host and the rest of the world

MT Single Switch Topology: Gatewayed ✔

Traffic to and from the bonded device will be to the same MAC level peer on the network Host A

MT Single Switch Topology: Local ✔

Each destination (Host B, Host C) will be addressed directly by their individual MAC addresses Switch

Bonding Modes: balance-rr ✔

✔ ✔

The only mode that permit a single TCP/IP connection to stripe traffic across multiple interfaces Packets may arrive out of order This mode requires the switch to have the appropriate ports configured for "etherchannel" or "trunking”

Bonding Modes: balance-xor ✔

✔

✔

Packets destined for specific peers will always be sent over the same interface Works best in a "local" network configuration Switch ports need to be configured for "etherchannel" or "trunking.

Bonding Modes: 802.3ad ✔ ✔ ✔ ✔ ✔

Standard Almost no switch configuration Distributes traffic by peer Same speed and duplex ARP monitor is not available in this mode

Bonding Modes: balance-tlb ✔ ✔

✔

Balances outgoing traffic by peer All incoming traffic arrives over a single interface ARP monitor is not available

Slide: 13

Bonding Modes: balance-alb ✔ ✔

✔

Almost the same as balance-tlb balances incoming traffic from local network peers device driver must support changing the hardware address while the device is open
