as for tomorrow…
your mobile can start your car and simplify your purchases
your house can become smart
your grandchildren living 6,000 miles away can whisper in your ear
high definition voice
you take part in your conference calls by the swimming pool

it’s like you can pick up Nadal’s aces from your living room
carpet fibre optics
you are able to store your files in a cloud…

developing the networks of the future
the challenges ahead respond to the massive increase in traffic: by 2015, we expect the standard level of
mobile data traffic to have risen by 26 times
expand coverage and increase our speed to keep pace with the digital revolution
constantly improve the quality of our services
renew our infrastructures while respecting the environment
![Page 18: Orange: towards an efficient - mit.edumedard/contentresearch/presentations/Gourdin... · Romania Moldova Poland France Slovakia Switzerland Austria Guyana Armenia Belgium Luxembourg](https://reader030.vdocuments.us/reader030/viewer/2022040710/5e116b51b67c0c4d5e29df54/html5/thumbnails/18.jpg)
Orange’s position (similar to other telcos)
to face these challenges:
– upgrading constantly the bandwidth is no longer a solution
there is a clear need to disseminate the contents closer
to the final users:
– essentially for most « popular » contents
– « closer » = inside the telco network
several objectives: – save bandwidth in our core and backhaul network
– enhance the QoS experienced by our customers
– provide new services, explore new markets,…
![Page 19: Orange: towards an efficient - mit.edumedard/contentresearch/presentations/Gourdin... · Romania Moldova Poland France Slovakia Switzerland Austria Guyana Armenia Belgium Luxembourg](https://reader030.vdocuments.us/reader030/viewer/2022040710/5e116b51b67c0c4d5e29df54/html5/thumbnails/19.jpg)
Orange’s strategy on CDN
main driving forces:
video traffic increasing
business models not in favour of
efficient network usage
ratio bandwidth vs storage cost more and more in favor of storage
![Page 20: Orange: towards an efficient - mit.edumedard/contentresearch/presentations/Gourdin... · Romania Moldova Poland France Slovakia Switzerland Austria Guyana Armenia Belgium Luxembourg](https://reader030.vdocuments.us/reader030/viewer/2022040710/5e116b51b67c0c4d5e29df54/html5/thumbnails/20.jpg)
Orange’s strategy on CDN
Several options/questions:
– rely on a CDN pure player, or
– manage or deploy own CDN solutions ?
– use transparent caching, or
– rely on fully managed CDN ?
– deploy unique CDN/caching solution, or
– adapt to each specific market ?
All these questions are currently
addressed by Orange…
less control
more control more gain/benefits
less gain/benefits
less complexity more complexity
![Page 21: Orange: towards an efficient - mit.edumedard/contentresearch/presentations/Gourdin... · Romania Moldova Poland France Slovakia Switzerland Austria Guyana Armenia Belgium Luxembourg](https://reader030.vdocuments.us/reader030/viewer/2022040710/5e116b51b67c0c4d5e29df54/html5/thumbnails/21.jpg)
future on CDNs
many difficult questions:
research can help
– how to deploy efficiently a caching solution ?
– predict popularity distributions, cache hit ratio (given replacement policy),…
– where to locate the caches, capacities, traffic redirections,…

future on CDNs
medium/long term trends:
– CDN interconnection
– how to operate jointly several CDNs
– cooperation between telco and CDN pure players
– find joint ways to improve traffic conditions for content delivery
– for instance through different content naming (ICN networks)
– mobile broadband traffic
– adapt solutions to mobile networks

Orange’s position regarding NC
In fixed networks:
– throughput gain not always very clear
pros:
(+++) robustness (against failures, uncertain demand pattern,…)
(++) improved QoS/QoE
(+) relative ease of implementation
cons:
(-) slight overhead (coding/decoding)
(--) additional enabler (deployment cost)
(---) complexity of management (difficult to track individual flows)
(---) legal issues (can we code together any content ?)

Orange’s position regarding NC
In mobile networks:
– probably much gain to expect from NC
– very promissing results by MIT/RLE
– more technical issues to consider…
– necessity to combine with global CDN strategy

Orange’s position regarding NC
conclusions:
– still unclear the potential benefits vs cost/risk
– theoretical results won’t bee enough to convince managers ;-)
– don’t forget the « operational » point of view !
