WebDec 20, 2024 · Cut-through switching is a method for packet-switching system, aiming to reduce network latencies to the minimum. This technique reduces latency through the switch when an Ethernet switch starts forwarding a packet before the entire packet has been received, normally, as soon as the destination address is processed. WebApr 14, 2024 · If you want cut-through, your switches cannot be chassis. They need to be top-of-rack switches with a single ASIC (no interconnects). The interface speed needs to …
