Detailed Explanation

Network bonding is the aggregation or combination of multiple LAN cards into a single bonded interface to provide high availability and redundancy. Network bonding is also known as NIC teaming. This pages shows how to bind multiple network interfaces into a single load balanced or fault-toleranced interface and so on. The Linux bonding driver allows system administrators to set up bonding interfaces with different modes. A bonding mode specifies the policy indicating how bonding slaves are used during network transmission. To achieve the maximum throughput and fault toleration, it is important to choose the proper bonding mode and the corresponding options for the setup In Netplan, the default is balance-rr (round robin). Possible values are balance-rr, active-backup, balance-xor, broadcast, 802.3ad, balance-tlb, and balance-alb. For Open vSwitch active-backup and the additional modes balance-tcp and balance-slb are supported

Mode	Description	Load balancing	Fault tolerance
balance-rr or 0	Round-robin policy. Transmits packets in sequential order from the first available slave through the last.	O	O
active-backup or 1	Active-backup policy. Establishes that only one slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The bond's MAC address is externally visible on only one port (network adapter) to avoid confusing the switch.
