Transcribed Image Text:5.04-4. Bellman Ford Algorithm - a change in DV (1, part 4). Consider the network below, and
suppose that at t=0, the link between nodes b and c goes down. And so at t=0, node b recomputes
its distance vector (DV) and sends out its new DV (as needed). At t=1 this new DV is received at b's
neighbors, who then perform their calculation and send out their new DVs (as needed); these new
DVs arrive at their neighbors at t=2, and so on. What is the last time in this network at which a DV
calculation will take place as a result of the link change at t=0?
