5.04-3. Bellman Ford Algorithm - a change in DV (1, part 3). Consider the network below, and suppose that at t=0, the link between nodes g and h goes down. And so at t=0, nodes g and h recompute their DVs. Following this recomputation, to which nodes will h send its new distance vector? (Note: to answer this question, you'll need to know some of the DV entries at g and h at t=0, but hopefully they'll be obvious by inspection). At t=0, the link (with a cost of 6) between nodes g and h goes down. all nodes nodes i and e and g only node e only nodes i and e only node i only node h does not send out its distance vector, since none of the least costs have changed to any destination.

Given the following network, answer the following questions: 1. Find the shortest route from node 1 to node 7. Use Dijkstra Algorithm and show temporary and permanent nodes at each step of your calculations. 2. Develop the mathematical model for the shortest route from node 1 to node 7. Write decision variables, objective function and constraints.
