Jim Brickmeier, Chief

" CDN deployments are often sized
for peak demand levels, for example
to support major live sporting events.
If CDN capacity is fixed, this can leave
servers idling and generating carbon
costs whenever traffic volumes are
lower than peak levels. These costs
can be readily calculated and used to
drive optimisations. "

Quantifying and
tackling the

is
complex.
There are multiple
visible and hidden contributors to
the global energy consumption in
video streaming networks, including
devices, CDN servers, head-ends,
and networking equipment.
" Networking equipment is agnostic

says
Yann Begassat, Business
Development Manager at Broadpeak
