Answer of HW

Answer of HW. Chapter 4. Answer of HW. p404 4 No VC number can assigned to the new VC; thus the new VC can not be established in the network. Each link has two available VC numbers. There are four links. So the number of combinations is 2 4 = 16. One example combination is (10,00,00,10).
