Bonding is a technique for binding multiple NIC's to a single network Bonding (also called NIC teaming or Link Aggregation) is a technique

network fault-tolerant, increase the performance or both to achieve different goals, like make the network fault-tolerant,
together. increase the performance or both together.
High-speed hardware like Fibre Channel and the associated switching
hardware can be quite expensive. By doing link aggregation, two NICs
can appear as one logical interface, resulting in double speed. This
is a native Linux kernel feature that is supported by most
switches. If your nodes have multiple Ethernet ports, you can
distribute your points of failure by running network cables to
different switches and the bonded connection will failover to one
cable or the other in case of network trouble.
Aggregated links can improve live-migration delays and improve the
speed of replication of data between Proxmox VE Cluster nodes.
