The estimated time of
migration
from IPv4 to IPv6
in
USM
using dual-stack
mechanism
is more or less need about four months shows in Figure 5.3.

times for
IPv6
deployment
in
USM [27]
For the conclusion, the migration process in the USM is based on the cost efficiency that
determine
by
four
factors:
hardware
cost,
software
cost,
labor
cost,
and
other
cost.
By
looking to these key
factors
the
university can determine
the estimation cost
that
need to
be spend during migration. Because all the routers and switches in USM already
upgraded the estimation cost
for the
migration
is
low, the
highest costs
that will
be spent
occurred on
the
labor and
unpredictable cost.
The estimation time
for
migrate
itself
will
take place around four months.
