Abstract
A method and a network device are provided for transferring data packets to a port according to the priority of the packets and, when a packet is dropped, providing, to the sender of the packets, an early notification that the packet was dropped. The priority of a packet can be determined according to data contained in the packet, e.g., an operation code of the packet, or according to a marking of the packet by the sender, e.g., a marking resulting from a weighted random early detection template. The early notification that the packet was dropped is in the form of message generated at the network device and sent by the network device to the sender of the packet. The network device obtains, from the packet to be dropped or from a connection table, the information required for the message to arrive at the sender.
