Network Teaming also is known as Ethernet Channel Bonding that enables two or more Network Interfaces Card (NIC) to work as a single VIRTUAL NIC card. This means the machines will be supposed to work on the virtual one and which may increase the bandwidth and provides redundancy of NIC Cards. This helps us in achieving redundant links, load balancing or fault tolerance networks in the production system. If one physical NIC is down or can say unplugged, it will automatically MOVE the RESOURCES to other NIC card. Channel/NIC bonding works with the help of the bonding driver in KERNEL. 

2 main types of Network Teaming:-

1. Load balancing (Round-Robin): In Load balancing, Both network cards are active all the time and dividing the workload for better data transmission. This provides better resource utilization and faster output.
2. Active-Backup: In Active-Backup: One network card is active at one time and another card will keep passive for backup. In case of active network card FAILURE, Passive card will start behaving as active to fulfil the user request.
