Abstract
It is quite easy to foresee that in the next years,
the future generation ultra-high speed network infrastructures
and equipments will be no longer constrained only by
their pure transport capacity, but also by their energy consumption
costs and environmental effects. In particular, large
network infrastructures are now widely recognized to play a
fundamental role in the emission of greenhouse gases in the
atmosphere, significantly affecting the environmental sustainability
of new evolutions in network architectures as well
as technological developments in communication devices. In
this paper, a novel eco-sustainable routing and wavelength
assignment algorithm, based on shortest path routing with
an adaptive link weighting function relying on an extension
of the OSPF-TE protocol to convey carbon footprint information,
has been proposed to decrease the network ecological
impact while balancing the traffic load and maintaining
acceptable connection-blocking rate. The trade-off between
load balancing and carbon footprint is also analyzed to evaluate
the effectiveness of the proposed strategy within the
context of a real world network.
