Abstract
Because of the static nature of the deployed optical
networks, large energy wastage is experienced today in
production networks such
as Telecom networks
.
With power-adaptive
optical
interfaces
and suitable
grooming procedures, we
propose the design of more energy efficient transport networks.
Optical network reconfigurations are performed
by GMPLS
node controllers according to monitored traffic information.
The
investigated energy reduction strategies are
simulated on two
large scale transport networks
(DT17
and
COST37).
The
results
show that the energy
savings
obtained
by
these
strategies depend
on the
variability of the carried traffic and the
characteristics of
the network topology
.
For
medium
size
DT17
network
significant
(more than 3
7
%)
power savings are achieved
only
with
symbol-rate
adaptation while
less
savings are achieved for
modulation
format
adaptation.
In case of
pan-Europea
n
COST37
network,
for both symbol-rate and modulation format adaptations
significant savings are obtained
.
Mixed adaptation
(jointly
performing symbol-rate and modulation format adaptations)
used
together
with optical grooming allows
up to
4
4
%
and
4
7
%
power savings in DT17
and
COST37
networks respectively,
close
to the
optimum power savings case
48,2
%
computed
when
the
power follows
exactly
the traffic
demand
pattern
