IP Routing Protocols and Internetwork Design: Delivery, Forwarding, and Routing Techniques, Slides of Network Design

An excerpt from a university course on IP Routing Protocols and Internetwork Design, focusing on the concepts of delivery, forwarding, and routing. It covers topics such as direct and indirect delivery, forwarding techniques, route method versus next-hop method, host-specific versus network-specific method, default method, simplified forwarding module in classless addressing, address aggregation, longest mask matching, and unicast routing protocols. The document also introduces autonomous systems and popular routing protocols.

DELIVERY

The network layer supervises the handling of the

packets by the underlying physical networks. We

define this handling as the delivery of a packet.

Direct Versus Indirect Delivery

Topics discussed in this section:

ETN 770: IP Routing Protocols

ETN 770: IP Routing Protocols 4

FORWARDING

Forwarding means to place the packet in its route to

its destination. Forwarding requires a host or a router

to have a routing table. When a host has a packet to

send or when a router has received a packet to be

forwarded, it looks at this table to find the route to the

final destination.
