WebJun 30, 2015 · RFS - Receive flow steering. While RSS solves the problem of balancing the load across many CPUs, it doesn't solve the problem of locality. In fact, the NIC has no understanding on which core the relevant application is waiting. This is where RFS kicks … WebReceive Packet Steering (RPS) is logically a software implementation of RSS. Being in software, it is necessarily called later in the datapath. Whereas RSS selects the queue and hence CPU that will run the hardware interrupt handler, RPS selects the CPU to perform … respectively.
