Complete each of the five problems below including the required tables and
submit in Moodle in PDF format.
1. Looking at Figure below, enumerate the paths from y to u that do not contain
any loops.
2. Repeat Problem 1 for paths from x to z, z to u, and z to w.
3. Consider the following network. With the indicated link costs, use Dijkstra’s
shortest-path algorithm to compute the shortest path from x to all network nodes.
Show how the algorithm works by computing a table similar to Table 4.3.
Answer:
Step N’

1 xv 7,v 6,v 3,x 6,x 6,x 8,x
2 xvu 7,v 6,v 3,x 6,x 6,x 8,x
3 xvuw 7,v 6,v 3,x 6,x 6,x 8,x

4. Consider the network shown in Problem above (3). Using Dijkstra’s algorithm,
and showing your work using a table similar to Table 4.3, do the following:
a. Compute the shortest path from t to all network nodes.
b. Compute the shortest path from u to all network nodes.
c. Compute the shortest path from v to all network nodes.
d. Compute the shortest path from w to all network nodes.
e. Compute the shortest path from y to all network nodes.
f. Compute the shortest path from z to all network nodes.
5. Consider the network shown below, and assume that each node initially knows
the costs to each of its neighbors. Consider the distance-vector algorithm and
show the distance table entries at node z.
