Traffic intensity is one of the important ratio which gives an insight into the queuing delays.

Discuss traffic intensity and its impact on the queue’s behaviour of a router for the following

cases: (i) Traffic Intensity >1 (ii) Traffic Intensity < 1 (iii) Traffic Intensity =1. (You have to

explain your answer with the help of mathematical equations and graph).

Simplify the following boolean function F. together with the don’t-care conditions d. and then express the simplified function in sum-of-minterms form:

F(A, B, C, D) =  Σ(4, 5, 7, 12, 13, 14)

d(A, B, C, D) =  Σ(1, 9, 11, 15)

Simplify the following boolean expression, using four-variable maps:

AB'C + B'C'D' + BCD + ACD' + A'B'C + A'BC'D

Simplify the following boolean expression, using four-variable maps:

A' B' C' D' + A'CD' + AB'D'+ABCD + A' BD

Simplify the following boolean function, using four-variable maps:

F(A, B, C, D) =  Σ(0, 2, 4, 5, 6, 7, 8, 10,

Simplify the following boolean function, using karnaugh maps:

F(w, x, y, z) =  Σ(2, 3, 12, 13, 14, 15)

Simplify the following boolean function, using three-variable maps:

F(x, y, z) =  Σ(1, 4, 5, 6, 7)
