Network Bonding as the name implies that it is the process of bonding or joining two or more than two network interfaces to create one interface. It helps in improving the network throughput, bandwidth, redundancy, load balancing as in case any of the interfaces is down; the other one will continue to work. Several types of Network Bonding are available that are based on the kind of bonding method.
Below are the different bonding types in Linux:
`) balance-rr or mode 0 – This is the default mode of network bonding that works on the round-robin policy that means from the first slave to the last, and it is used for fault tolerance and load balancing.
2) active-backup or mode 1 – This type of network bonding works on the active-backup policy that means only one slave will be active and other will work just when another slave fails. This mode is also used for fault tolerance.
3) balance-xor or mode 2 –This type of network bonding sets an exclusive or mode that means source MAC address is XOR’d with the destination address, and thus it provides fault tolerance and load balancing.
4) broadcast or mode 3 –This mode sets a broadcast mode to provide fault tolerance, and it should be used for particular purposes. In this type of network bonding, all transmissions are sent to all slave interfaces.
5) 802.3ad or mode 4 –This mode will create the aggregation groups, and all the groups will share the same speed. For this, mode sets an IEEE 802.3ad dynamic link aggregation mode. It is done by particular switch support that supports IEEE 802.3ad dynamic link.
6) balance-tlb or mode 5 –This mode sets a transmit load balancing mode for fault tolerance and load balancing and does not require any switch support.
7) balance-alb or mode 6 –This mode sets an active load balancing to achieve fault tolerance and load balancing.
