A network interface controller (NIC) capable of facilitating efficient management of idempotent operations is provided. The NIC can be equipped with a network interface and an operation management logic block. During operation, the network interface can receive a request for an operation from a remote device. The operation management logic block can determine whether the request for an idempotent operation. If the request is for an idempotent operation, the operation management logic block can execute the operation to generate an outcome and generate a response comprising the outcome for responding to the request.
