Our discussion of network-layer addressing and forwarding thus far has been without reference to any particular computer network. In this section, we'll turn our attention to how addressing and forwarding are done in the Internet. We'll see that Internet addressing and forwarding

Up to now in this section, we've mostly looked at the network layer's forwarding function. We studied that when a packet arrives to a router, the router indexes a forwarding table and determines the link interface to which the packet is to be directed. We also studied that routing

Distance-Vector Algorithm

When a node running the DV algorithm detects a change in the link cost from itself to a neighbor (Lines 10-11), it updates its distance vector (Lines 13-14) and, if there's a change in the cost of the least-cost path, informs its neighbors (Lines 16-17) of its new distance vector, Figure
