Again, a similar discovered set of paths that are considered for the hop count metric are also consid-
ered in the selection process of the delay metric. Since the objective of this metric is to minimize the
delay, a packet transmitted through the selected path must experience the lowest delay among all. In
delay calculation of a path, the total propagation delay and total transmission delay are considered,
that is, d = τ + ς, where
=
is the propagation delay and
=
is the transmission
delay. Algorithm details are given in Algorithm 15.6.
