Abstract
A method for processing network packets in a network device is described. A network packet is stored in a transient buffer as the network packet is being received at an ingress port of the network device. After at least a first portion of the network packet has been received and before the entire network packet has been received: the first portion is processed to identify an egress port of the network device from which the network packet is to be transmitted; a congestion state of the egress port is determined; and the network packet is selectively transferred from the transient buffer to the identified egress port for transmission from the network device or a different action is performed on the network packet, based on the congestion state.
