Abstract
A data structure represented by a single 32 bit word or 'primary control marker' that is inserted ahead of a header of a packet at the front of a flow of packets that is being processed by a network processor in a network device. The primary control marker includes the results of calculations that have been accelerated through the use of hardware (ASICs) to perform certain tasks in advance for the network processor. Because the insertion of in-band information has an impact on packet stream throughput, both the location of the insertion in the packet header and the type of results that are included in the primary control marker have an effect on the overall performance of the network processor, The data structure includes the results of IP header checksum verification, MAC level filtering and classification, VLAN indication, Flow Hash Index Calculation and Channel Identification.
