Question: Consider the network shown in Fig. involving one OD pair with a given input rate rand three links with capacities C1, C2, and C3, respectively. Assume that C1 = C3 = C, and C2 > C, and solve the optimal routing problem with cost function based on the M/M/1 delay approximation and r between 0 and 2C + C2.
