CIRCUIT SWITCHING
Consider the circuit-switched network shown in the figure below, with circuit switches A, B, C, and D. Suppose there are 14circuits between A and B, 14 circuits between B and C, 15 circuits between C and D, and 13 circuits between D and A.
Suppose that 17 connections are needed from A to C, and 11 connections are needed from B to D. Can we route these calls through the four links to accommodate all 28 connections?
HINT Taking from the previous question, is the sum of the two connections greater than the value we calculated in question 2?
A、Yes
B、No
