Cut-through switching techniques, such as Multiprotocol over ATM (MPOA) and Multiprotocol Label Switching (MPLS), enable the establishment of direct communication paths between clients and servers on different subnets. The traffic does not have to be processed directly through the router. Cut-through switching promotes enhanced network performance, and enables any layer-3 protocol to issue QoS requests.
