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).

This first chapter concentrate on identifying these restrictions and presents a new architecture, known as multipleprotocol (5)switching, that provides so
