Consider a VC network with a 2-bit field for the VC number. Suppose that the network wants
Question:
In answering the following questions, keep in mind that each of the existing VCs may only be traversing one of the four links.
a. If each VC is required to use the same VC number on all links along its path, what VC number could be assigned to the new VC?
b. If each VC is permitted to have different VC numbers in the different links along its path (so that forwarding tables must perform VC number translation), how many different combinations of four VC numbers (one for each of the four links) could be used?
