Abstract
Methods and systems for a network device. The network device includes a temporary memory storage device having a plurality of storage locations that are used to store packets received by a plurality of sub-ports. The network device includes a cut-through estimation circuit that estimates a cut-through threshold value based on which a certain portion of a packet has to be received and stored at one of the plurality of storage locations before the packet can be processed by one of the sub-ports that received the frame. The cut-through threshold value varies based on an operating speed of a network link the packet is received on, an operating speed of a network link the packet is transmitted on, and a protocol used for receiving and transmitting the packet.
