Abstract
An apparatus for and a method of reducing the packet length count processing of data packets in a network device. The apparatus and method determine the length and end of a packet at the ingress point of the network computing device, e.g., a switch or router, using a single counting function. After the counting function verifies the length of the data packet, a signal indicating the length of a data packet is generated. This packet length indicator signal is then propagated throughout the system along with the data packet itself. The packet length indicator signal is then used at all decision points that involve the data packet. The packet length indicator signal itself is generated so as to indicate the beginning of the start of the data packet in addition to the end of the data packet, thus indicating the length of the packet. This obviates the need for the length of the packet to be counted over and over again in the course of processing the data packet within the switch or router.
