Level 3 (network layer) load balancing works with IP packets and uses information from IP and transport protocol (TCP/UDP) headers to distribute traffic among servers.

Main features:

• Works with IP addresses and ports.
• Can use algorithms, for example, round-robin, based on source/destination IP address or port.
• Usually implemented in routers or load balancers (L3 load balancers).

Example: the load balancer receives a packet, checks the destination IP address and port, selects one of the servers in the pool, and redirects the packet there, changing the destination IP address.

This approach is effective for distributing load at the network level without inspecting application content.
