Algorithm 1 Local Queue Bandwidth Adjustment Algorithm

Input:

w_{q}

t_{q}

c_{q}

T_{q}

q = 5, 6, 7

Output:

B_{q}

D_{q}

1:
Initialize $B_{q} = w_{q}$ , $D_{q} = 0$ , $c_{q} = q + 1$ , $P o r t = 100$
2:
$A v g Q_{q} = w_{q} \times t_{q}$
3:
$S u m = \sum_{q = 5}^{7} {(A v g Q_{q} \times c_{q})}^{\frac{1}{2}}$
4:
if $t_{q} \leq T_{q}$ then
5:
$B_{q} = P o r t \times {(A v g Q_{q} \times c_{q})}^{\frac{1}{2}} / S u m$
6:
$D_{q} = S u m \times {(A v g Q_{q} / c_{q})}^{\frac{1}{2}} / P o r t$
7:
else
8:
notify the administrator to adjust $T_{q}$
9:
end if
