The device checks whether the flow (sequence of related packets) is | The device checks whether the flow (sequence of related packets) is received and packed. Packets of unknown flow are forwarded to the networking stack. Meanwhile, if the flow is known, NAT is applied (if matched) and the packet is forwarded to the correct destination port (fast path) to bypass certain layers or packet processing process. As a result, we have a higher throughput and reduced the CPU load. This process is called <b>software flow offloading</b>. {{#switch: {{{series}}} | RUTX | RUTM | RUTC | OTD500 = <b>Hardware flow offloading</b> is used to execute functions of the router using the hardware directly, instead of a process of software functions. | #default =}} | ||
