# Network Card Bond

+ Adequate bandwidth (≥10 Gigabit NICs) to ensure high availability of the network through bonding technology (primary-secondary mode bond1 recommended)
+ Insufficient bandwidth (<10 Gigabit NICs) Increase network bandwidth throughput through bonding technology (balanced polling mode bond0 is recommended)

------------------------------------------------------------

There are generally two types of requirements for bonding network cards
- Bandwidth Satisfaction (≥10 Gigabit NICs) to ensure high availability of the network through bonding technology
- Insufficient bandwidth (<10 Gigabit NICs) Increase network bandwidth throughput through bonding technology
Here we recommend that you use the master and backup mode to improve the high availability of the network line
