Intelligent Content Networking
Executive Summary
The rapid growth of consumer Internet traffic, mainly due toincreased viewing
of video content via their broadband connections (known as ?Over-the-Top?
Video or OTT Video), is driving increased stress on serviceprovider networks
and business models. The frequency, duration, and resolution ofcontent
requests are increasing, which has a dramatic effect onbandwidth requirements.
As we enter into the era of Hyperconnectivity, more and moredevices
are accessing this rich content anywhere, and at anytime. Demandis accelerating
quickly as more content (for example mainstream movies and TVshows) is
becoming available and broader set of Internet-connected devicesare able to
access it.
The ability to manage the delivery of certain content types andreduce
bandwidth requirements over Middle Mile, core, and Internettransit networks
can improve profitability for service delivery. IntelligentContent Networking
reduces the strain on the network and improves the userexperience by serving
a broad range of popular, frequently accessed content closer tothe subscriber,
reducing service delivery and internet transit bandwidthrequirements.
Video Takes Over
From peer-to-peer downloads to online gaming, from instantmessaging to
email, from web to video the amount of internet traffic isgrowing significantly.
Video content is rapidly changing the composition of consumerinternet traffic
and is anticipated to make up nearly 60% of requests by 2014.The growth of
video will continue as subscribers? viewing habits change frombroadcast to
on-demand?at home and on mobile devices?and with higherdefinition
and increased availability of mainstream content, such as moviesand television
series, being offered via the Internet.

Irrespective of the type, OTT content puts significant stress onthe network
because it must traverse internet peering connections, corenetwork infrastructure,
Middle Mile connections, and finally the access network to bedelivered.
An individual subscriber?s request for video content, where auser is highly
utilizing their connection for a long period of time, has acompound effect on
the network as subscribers? linear-based requests areaggregated, causing
network congestion and sub-optimal quality of experience (QoE).
The traditional approach to address bandwidth growth, reducecongestion,
and ensure customer satisfaction is via incremental networkoverlays and
increased Internet transit capacity. This is effective toaddress bandwidth
requirements, but it?s not efficient from an economic standpointas overlays
drive additional CAPEX and OPEX. Considering that the averagerevenue per
user (ARPU) will stay static (if not diminish with increasedcompetition), this
continued investment fuels a divergence of cost and revenue,leading to less
profitable service offerings.
Secondly, as a subscriber?s internet connection usage grows morebandwidthintensive
with OTT and other sources of video, the experience willdeteriorate.
This is based on time to download and view content as well assystem response
times for control commands (play, pause, etc.). As expectationscontinue to
become more difficult to meet, more service complaints will belogged and
subscriber churn will increase as they move to competitiveservice offerings.
An alternative content delivery approach, that is beneficial toboth service
provider and customer, is needed. This approach will need todeliver content
effectively and efficiently, provide a high QoE for theend-customer, and limit
the service providers? requirements to augment the network.
