The 4 Keys to
Telco CDN Success
Introduction
Until recently, telecommunications service providers could operate profitably by nurturing
legacy businesses and harvesting new revenues from locked-in customers. Today, however,
societal and technological changes have caught these companies in a cost-revenue squeeze.

Deregulation and competitive access. Time and place shifting. The ubiquity
of mobile phones. Voice-over-Internet.

All have had a profound effect on network operators and caused significant
harm to once reliable revenue streams; none so ominous as the threat that
customers will cut the cord and sever their telco relationships entirely.

As traditional revenue streams ebb, telcos and other Internet Service
Providers (ISPs) also face a huge challenge on the cost side. With
online video traffic poised to more than quadruple by 2013,
service providers will need to accommodate massive “over the
top” (OTT) demand on their networks. But ISP subscriber
revenue will not be sufficient to offset the investment
levels necessary to grow bandwidth that quickly.

The combined effect of major cost impacts and shrinking revenues is a major challenge to
profitability.

Telcos are not sitting idly by, however. They are pursuing new strategies that play on their
inherent strengths — ownership of the network infrastructure and direct relationships with
end users and content owners — to reduce capacity investments and create new revenue
streams. One area in which telcos are leveraging these strengths is online video content
delivery.

Built-in factors like those below give telcos a natural competitive advantage over pure-play
commercial CDNs:

    • Better video quality of experience
    • Lower cost structure
    • Ability to leverage unique business models

But having built-in advantages and fully capitalizing on them are two different things.
With this white paper, we will reveal four key success factors necessary for Telco CDNs to
effectively harness their competitive edge and realize success.




       IP Video Management Analytics                                                           1
1. Optimize Quality of Service
Peek into most households these days and you’ll see a revolution in process. A radical
transformation in which viewers of broadcast content are no longer bound by traditional
TV physics. Instead they are free to view what they want, when they want, where they
want, across a multitude of devices.

But for this revolution to fully take hold —
for viewers to actually take advantage
of all this new-found freedom — the
delivered content must be of the
highest quality. In a world increasingly
accustomed to an uninterrupted flow
of HD programming, nothing short of
that will do.

Low resolution and other quality issues
might be forgiven by people watching
short video clips on their desktops, but
not by audiences considering internet
video as a replacement for cable or
satellite TV services.

Such is the challenge for OTT and
IPTV content providers. If they are to
successfully compete with established
pay-TV offerings, they must deliver
a consistently reliable, high quality
viewing experience.

To narrow the quality gap will require that OTT and IPTV content be cached and delivered
as close to the end user as possible. This minimizes the distance that video data travels
over the general internet and delivers it more quickly and reliably.

Traditional “pure play” CDNs have difficulty getting the content close enough to the
end user because they only deliver to the edge of an ISP network. The final stage of the
content’s journey is then delivered over-the-top, with no guarantees on its quality of
service (QoS).




        IP Video Management Analytics                                                       2
Telco CDNs, on-the-other-hand, own the network and the entire “last mile” — the final
leg that video content travels on its way to the end user. This enables the telco to cache
content deep in its network, avoiding congested upstream areas of its network or the
internet at large. So, most last mile delays and disruptions are eliminated. This “deep
caching” creates an important inherent advantage for telcos competing in the CDN space.

To fully capitalize on these inherent advantages, though, Telco CDNs must focus on
maintaining QoS and eliminating any service irregularities that might compromise it.

This demands an ability to quickly isolate and correct service quality issues at a very
granular level. They need to be able to quickly answer critical questions such as:

    • What content assets are we having difficulty serving?
    • Which geographical areas are experiencing suboptimal quality?
    • Which POPs in our network are producing the most delivery problems?

In fact, the real questions that need answering will represent a compounding of the
questions posed above. For example, which POPs are having trouble delivering specific
content to specific geographical areas? Only this level of specificity will allow the network
operator to quickly and precisely identify the sources of quality problems.

Failure to mind these issues at this level of detail may result in squandering the telco’s
inherent advantage. As a result, despite a telco’s “head start,” it may end up offering
inferior QoS than the off-network competition.

Fortunately, the Skytide Insight for Content Delivery Networks reporting & analytics
solution enables Telco CDNs to drill down across multiple dimensions simultaneously — by
customer, edge location, geography, etc. — to swiftly answer these types of questions and
uncover the root cause behind service quality issues.




       IP Video Management Analytics                                                            3
2. Maintain Cost Advantage
By virtue of owning the underlying network transit, Telco CDNs have a built-in cost
advantage over traditional CDNs, which must lease bandwidth from network operators
and build the operator’s margin into their own cost structures.

To maintain their cost advantage, however, Telco CDNs must optimize the efficiency of their
networks, with an emphasis on capacity planning and capacity management. Otherwise, a
third-party CDN that runs a tight ship can easily make up for the margin advantages and end
up offering a superior cost structure.

Capacity Planning

Optimal capacity provisioning requires a
deep understanding of demand trends;
not just average demand but peaks as
well. To identify peak capacity, in turn,
requires an ability to drill down to very
fine levels of time granularity. It also
calls for an understanding of traffic
broken out by dimensions such as:

    • Geography

    • Edge location

    • Media format

Only by viewing demand trends in this detailed, multidimensional way can one go beyond
the basics — understanding how much capacity to add to the network as a whole — to
understand more complex needs such as:

    • How many POPs to deploy
    • Where to locate them

    • How much capacity to provision at each POP

    • How much capacity to allocate to different media formats or services

For example, simply taking a one-dimensional look at the traffic through a specific POP
may give the impression that its traffic is growing and that capacity should be added.
Overlaying the POP dimension with the geographical dimension, however, may show that
traffic increases at this POP are actually the result of load-balancing from other POPs
that have reached their capacity limits.




       IP Video Management Analytics                                                          4
The multidimensional approach allows you to see beneath the surface and expose the
underlying truth – that it is really those other POPs that need increased capacity.

Capacity Management

Capacity management requires deep insight into traffic patterns and network topology.
By understanding this data at a very atomic level, CDN operators can actually shape their
traffic profiles and manage peak loads via strategies like:

    • Demand driven routing / load balancing

    • Dynamic Pricing

    • Access controls

In essence, these are all different ways of controlling which users can retrieve which
content from which POPs at which times.

The control mechanism may just involve routing selected traffic to different POPs in order
to avoid congestion at peak times. Network operators with end-to-end control of the
video supply chain – telcos that run their own IPTV services — may have more creative
options at their disposal. For instance, they can “shave” peaks by blocking access to hot
content by non-subscribers or by charging more to view it at peak times.

Properly managing these methods requires a deep understanding of demand trends across
geographical areas, POPs, customer types and content categories. This understanding can
only be achieved with tools that provide granular and multidimensional views into
operational data.

In summary, optimal provisioning and management of capacity require Telco CDNs to
measure operational performance in a multidimensional way. Only then can they precisely
forecast demand, shape traffic, and optimize their network topology.

Skytide Insight for CDNs makes it possible for Telco CDNs to do just that, enabling them to
track essential volume measures by time, edge location, ISP, geography, media format,
and a multitude of other dimensions.




       IP Video Management Analytics                                                          5
3. Contribute to Customer Success
To make their bet on content delivery pay out, Telco CDNs must ultimately contribute to
the success of their content owner customers; many of whom first established themselves
as print and broadcast properties and are now struggling to create viable digital media
businesses.

To help content owners to navigate the uncharted waters of Internet video,
Telco CDNs must provide them with tools to optimize their content
portfolios and answer essential questions such as:

    • What types of content do viewers prefer?

    • Which content should be promoted in featured
      playlists or social media?

    • Which encodings, bitrates, and formats should be
      produced for mobile, desktop, and big-screen viewing?

Skytide Insight for CDNs enables Telco CDNS to become true partners and trusted advisors
to their customers by allowing them to answer questions crucial to their business.


4. Establish New Business Models
Telco CDNs also have the opportunity to create more sustainable business models that
more equitably benefit key links in the content-to-consumer value chain. BT Wholesale’s
“Content Connect” and its B2B2C business model appear to be a bellwether in this regard.

By guaranteeing HD-like quality of service, BT offers ISPs and OTT content owners with a
viable opportunity to create a user experience for which they can charge a fee.

But the success of these evolving business models also hinges on the ability of
participants in the value chain to access and track data relevant to managing their
business. BT can’t just claim to offer better QoS to subscribers of its premium level
service; they must prove it.

With Skytide, network operators can create secure portals for customers and business
partners, providing them access to data specific to their own operations. The inherent
multi-dimensional nature of Skytide’s reports allows:

    • Content owners to understand content consumption across all networks or ISPs
    • Resellers (ISPs) to understand traffic patterns across all content owners
    • All entities to understand how traffic and QoS vary across service levels




       IP Video Management Analytics                                                       6
Conclusion
Telco CDNs have several advantages over traditional CDNs in helping OTT and IPTV providers
to deliver a genuinely competitive pay-TV service. Among these advantages are:

    • Deeper network caching and last mile delivery that enable them to guarantee better
      quality of service.
    • Built-in cost advantages by virtue of owning the network and not having to lease
      bandwidth.
    • Close customer relationships that can be further strengthened by providing them
      with the tools to better understand and manage their content portfolios.

Success for Telco CDNs ultimately rests on their ability to capitalize on these advantages,
however, which requires that they be able to measure and manage their network
performance at a very detailed level and make adjustments accordingly.

Only Skytide Insight for CDNs can make that happen quickly and reliably because:

    • It is able to provide multidimensional views of streaming data at a very detailed
       level.

    • It is highly configurable and extensible, to accommodate new business models.

    • It is built on top of Skytide’s patented architecture, which can process huge volumes
       of high velocity data and turn it into useful reports in less than an hour.

    • It is battle tested. Skyide has been in the CDN trenches for years, gathering
       requirements from over 30 of the world’s leading telco and digital media companies.

Along the way, we’ve come to know exactly what content delivery providers need —
especially emerging Telco CDNs. Which is why Skytide is used by the likes of British
Telecom, Telecom Argentina, Telecom Italia, Telefonica and Telstra.

It also calls for an understanding of traffic broken out by dimensions such as: • Geography • Edge location • Media format Only by viewing demand trends in this detailed, multidimensional way can one go beyond the basics — understanding how much capacity to add to the network as a whole — to understand more complex needs such as: • How many POPs to deploy • Where to locate them • How much capacity to provision at each POP • How much capacity to allocate to different media formats or services For example, simply taking a one-dimensional look at the traffic through a specific POP may give the impression that its traffic is growing and that capacity should be added. Overlaying the POP dimension with the geographical dimension, however, may show that traffic increases at this POP are actually the result of load-balancing from other POPs that have reached their capacity limits.

Capacity Management Capacity management requires deep insight into traffic patterns and network topology. By understanding this data at a very atomic level, CDN operators can actually shape their traffic profiles and manage peak loads via strategies like: • Demand driven routing / load balancing • Dynamic Pricing • Access controls In essence, these are all different ways of controlling which users can retrieve which content from which POPs at which times. The control mechanism may just involve routing selected traffic to different POPs in order to avoid congestion at peak times. Network operators with end-to-end control of the video supply chain – telcos that run their own IPTV services — may have more creative options at their disposal. For instance, they can “shave” peaks by blocking access to hot content by non-subscribers or by charging more to view it at peak times. Properly managing these methods requires a deep understanding of demand trends across geographical areas, POPs, customer types and content categories. This understanding can only be achieved with tools that provide granular and multidimensional views into operational data. In summary, optimal provisioning and management of capacity require Telco CDNs to measure operational performance in a multidimensional way. Only then can they precisely forecast demand, shape traffic, and optimize their network topology. Skytide Insight for CDNs makes it possible for Telco CDNs to do just that, enabling them to track essential volume measures by time, edge location, ISP, geography, media format, and a multitude of other dimensions.

Contribute to Customer Success To make their bet on content delivery pay out, Telco CDNs must ultimately contribute to the success of their content owner customers; many of whom first established themselves as print and broadcast properties and are now struggling to create viable digital media businesses. To help content owners to navigate the uncharted waters of Internet video, Telco CDNs must provide them with tools to optimize their content portfolios and answer essential questions such as: • What types of content do viewers prefer? • Which content should be promoted in featured playlists or social media? • Which encodings, bitrates, and formats should be produced for mobile, desktop, and big-screen viewing? Skytide Insight for CDNs enables Telco CDNS to become true partners and trusted advisors to their customers by allowing them to answer questions crucial to their business. 4. Establish New Business Models Telco CDNs also have the opportunity to create more sustainable business models that more equitably benefit key links in the content-to-consumer value chain. BT Wholesale’s “Content Connect” and its B2B2C business model appear to be a bellwether in this regard. By guaranteeing HD-like quality of service, BT offers ISPs and OTT content owners with a viable opportunity to create a user experience for which they can charge a fee. But the success of these evolving business models also hinges on the ability of participants in the value chain to access and track data relevant to managing their business. BT can’t just claim to offer better QoS to subscribers of its premium level service; they must prove it. With Skytide, network operators can create secure portals for customers and business partners, providing them access to data specific to their own operations. The inherent multi-dimensional nature of Skytide’s reports allows: • Content owners to understand content consumption across all networks or ISPs • Resellers (ISPs) to understand traffic patterns across all content owners • All entities to understand how traffic and QoS vary across service levels IP Video Management Analytics 6
  • 8. Conclusion Telco CDNs have several advantages over traditional CDNs in helping OTT and IPTV providers to deliver a genuinely competitive pay-TV service. Among these advantages are: • Deeper network caching and last mile delivery that enable them to guarantee better quality of service. • Built-in cost advantages by virtue of owning the network and not having to lease bandwidth. • Close customer relationships that can be further strengthened by providing them with the tools to better understand and manage their content portfolios. Success for Telco CDNs ultimately rests on their ability to capitalize on these advantages, however, which requires that they be able to measure and manage their network performance at a very detailed level and make adjustments accordingly.
