== Software techniques ==
Software techniques like RPS and RFS employ one of the CPU cores to steer incoming packets across the other cores of the processor. This comes at the cost of introducing additional [[Inter-processor interrupt|inter-processor interrupts (IPIs)]]
The benefits of a software solutions is the ease in implementation, without having to change any component (like the [[Network_interface_controller|NIC]]) of the currently used architecture, but by simply deploying the proper [[Loadable kernel module|kernel module]]. This benefit can be crucial especially in cases where the server machine can't be customized or accessed (like in [[Cloud computing#Infrastructure as a service (IaaS)|cloud computing]] environment), even if the network performances could be reduced as compared the hardware supported ones.<ref name="RPS linux news (LWM)">{{Cite web|title=RPS linux news (LWM)|url=https://lwn.net/Articles/362339/|access-date=2025-07-08|website=lwn.net|publisher=Linux Weekly News|language=en-US}}</ref><ref name="RPS by redhat">{{Cite web|title=RPS by redhat|url=https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/6/html/performance_tuning_guide/network-rps|access-date=2025-07-08|website=docs.redhat.com|publisher=Red Hat Documentation|language=en-US}}</ref><ref name="RFS by nvidea" />
