Telcom 2110 Network Design Homework #7 Solution, Spring 2010 1. Using the Delite network design tool , load the input file mux1.INP (use File menu – read input file box.) . This input describes a 15 node network. Using the MENTOR design algorithm, with threshold clustering, parameters RPARM = .4, WPARM = 1.00, NCLST 4 (the max size of cluster), slack = 0.1, vary alpha and the utilization to produce 5 different network designs. Compare the designs on the basis of Cost and reliability. MENTOR algorithm Alpha = 0.2, Utilization = 0.8 Alpha = 0.5, Utilization = 0.8

Varying the utilization has more effect on cost. As the utilization increases, the cost and reliability decrease. 2.
