ABSTRACT:
A last router in the route of a packet determines when a packet is at the last hop prior to reaching its destination, based on information conveyed in the routing table that the destination is a directly-connected host, and can then convey that information to the host by setting the TTL to zero in the packet being forwarded to its final destination. The host, being so informed that the packet is destined for its IP address, can thereby eliminate the IP address table search for the destination IP address of the incoming packet against the list of its allocated IP addresses to determine if the packet is destined for that host, thereby providing significant performance enhancements to the network system by enabling a receiving host to skip the IP address lookup process and immediately consume the received packet.
