Devices, systems, methods, and processes for flow entropy management using network address translation (NAT) scheme are described herein. Typically, due to fewer flows and high bandwidth demands in backend data center networks, hash distribution algorithms may exhibit bias, leading to congestion on certain network paths while others remain underutilized, a phenomenon known as low flow entropy. To address the low flow entropy problem, a network interface controller (NIC) decomposes a traffic flow into multiple flowlets and applies a NAT operation on each flowlet. In the NAT operation, an actual source port value of a flowlet is replaced with a unique unused source port value to make the flowlet look like a different traffic flow to a switch. Thus, the switch processes each flowlet as a different traffic flow and uses load balancing schemes to distribute the flowlets across various network paths. Thus, improving the flow entropy of the network.
