In this problem do not resort to wavelength conversion but assume that wavelengths can be reused in different parts of a network.
( a ) Show that the minimum number of wavelengths required to connect N nodes in a WDM network is as follows:
• N 1 for a star network.
• ( N /2) 2 for N even or ( N 1) ( N + l)/4 for N odd in a bus network.
• N ( N - l)/2 for a ring network.
( b ) Draw example networks and their wavelength assignments for N = 3 and 4.
( c ) Plot the number of wavelengths versus the number of nodes for star, bus, and ring networks for 2 N 20.
