Hello wisly,
Network Bonding, also known as Network Teaming or Link Aggregation, is a technique used in Linux to combine multiple network interfaces into a single, high-bandwidth virtual interface. There are several modes of Network Bonding in Linux, each with its characteristics and use cases. The most common modes of Network Bonding in Linux are:- Mode 0 (balance-rr): In this mode, packets are transmitted in a round-robin fashion across all available interfaces, providing load balancing and fault tolerance. It does not require any special switch support and is useful for small network configurations.
- Mode 1 (active-backup): In this mode, one interface is active and the other interfaces are in standby mode. If the active interface fails, the standby interface takes over. It is useful for servers that require high availability and redundancy.
- Mode 2 (balance-xor): In this mode, the outgoing traffic is balanced using a XOR algorithm based on the MAC addresses of the interfaces. It provides load balancing and fault tolerance but requires switch support for link aggregation.
- Mode 3 (broadcast): In this mode, packets are sent simultaneously to all interfaces, providing fault tolerance but not load balancing. It is useful for applications that require reliable transmission.
- Mode 4 (802.3ad): In this mode, multiple links are aggregated into a single logical link using the IEEE 802.3ad standard. It requires switch support and provides load balancing and fault tolerance.
- Mode 5 (balance-tlb): In this mode, outgoing traffic is balanced based on the current load of each interface, while incoming traffic is received on the active interface. It does not require switch support and is useful for small network configurations.
- Mode 6 (balance-alb): In this mode, incoming and outgoing traffic is balanced based on the current load of each interface, using both MAC and IP address hashing. It does not require switch support and is useful for small network configurations.
Each mode has its advantages and disadvantages, and the appropriate mode should be chosen based on the specific requirements of the network configuration.
