Traditional IP packet forwarding analyzes the （ 1）IP address contained in then network layee header of each packet as the packet rravels from its sourse to its final destination. A router analyzes the destination IP address independently at each hop in the network. Dynamic （ 2） protocols or staitic configuration builds the database needed to analyze the destination IP address(the routing table). The process of implementing traditional IP routing also is called hop-by-hop destination-based （ 3）routing. Although successful,and obviously widely deployed,certain restrictions,which have been realized for some time,exist for this method of packet forwarding that diminish its （ 4）.New techniques are therefore required to address and expand the functionality of an IP-based network infrastructure.
