Given the figure in P10.19 as the connectivity graph of a network, you are allowed to go through only two steps of the Bellman-Ford algorithm at each node so that their complexity (and hence the time required) can be kept to a low value. What is the impact on shortest path calculations? Comment on the accuracy of the procedure?
Since the Bellman-Ford algorithm manages to find the shortest path to n-hop
nodes in n iterations, the given graph will be correctly evaluated. The procedure
will not be accurate for larger networks. However, running the procedure on all
nodes might produce correct routing by using other distributed methods.
