Consider the 4-partition system again. This time, N
AB
= 3, N
BC
= 2, and N
CD
= 4:
Then
(1-hop)
AB = (5 x 2) x 3 = 30
BC = (2 x 5) x 2 = 20
CD = (5 x 2) x 4 = 40
(2-hop)
AC = (AB)(AC) / 2 =
AC = 30 x 20 / 2 = 600 / 2 = 300
BD = (BC)(CD) / 5 =
BD = 20 x 40 / 5 = 800 / 5 = 160
(3-hop)
AD = (AB)(BC)(CD) / (d
B
x d
C
) =
AD = 30 x 20 x 40 / (2 x 5) = 24,000 / 10 = 2400
All Paths
30 + 20 + 40 + 300 + 160 + 2400 = 2950.
(Again, the figure is a maximum, because if you omit certain signal types from certain paths, the
number of paths decreases. The calculations for that situation are not worth the trouble.)
Your tieline configuration will probably be more complex than the examples given here.
Complex configurations can be decomposed into simpler parts and the two formulas (given
under
Simple Tielines and Multi-Hop Tielines on page 447) can then be applied.
A
(HD)
d = 5
C
(HD)
d = 5
B
(SD)
d = 2
D
(SD)
d = 2
