Not yet answered Marked out of 20.00 P Flag question a. For the below shown topology, each link represents two fibers (one pair) for transmission in each direction. You will notice that there are four nodes and two hubs. Consider the following requested links by design and give the wavelength assignment for the different links taking into account that you need to minimize the number of wavelengths consumed: 1->3, 1->4, 2->3, 2->4, 3->1, 3->2, 4->1, 4->2 and 4->3. end node 1 3 2 hub hub b. Now consider the following unidirectional ring where each directed link represents one fiber with traffic traveling clockwise. Specify the minimum number of required wavelengths in order to achieve the matrix of communications provided. node 1 3 j- 1 2 3 4 5 6 i=1 foo 1000] 2000 100 3 0 0 0 0 20 4 000001 5 0 2 0 0 0 0 6 LO O O O O O traffic matrix: entry (i,j) is traffic from node i to nodej.
