IP Migration will allow new added-value
services deployment for users
Enabling a full IP ecosystem to offer “easy-to-connect &
use” services around a more flexible architecture:
•
Multiroom TV on PC
•
Network Storage (Churn reduction/Arpu generation)
•
Remote home monitoring (energy saving) with client
software hosted in GTW/STB
•
Home Telepresence (driven by telecommuting)
•
N-screens services convergence (PC, TV, Mobile)
•
OTT converged services
•
Enhance the user experience with things like Fast

Access Network Architectures
•
All current SP network architectures have an IP
component
•
At some point, the majority of the architectures are almost
identical
•
The “Last-Mile”, or access portion, and CPE devices define
the differences between approaches
•
Decisions on the access approach are made based on:
Legacy
Cost
Maturity of technology
Religion
•
Cisco Systems can support your business at almost every
level regardless of the approach taken.

Video = the Killer App
•
Standard Definition MPEG2 Digital Video ~ 4mbps
•
High Definition MPEG2 Digital Video ~ 14 – 19mbps
•
MPEG4 reduces the data rates by 50%+
•
Available Access Data Rates today:
CATV (Mostly Analog and QAM video):
Most MPEG Video = referenced above
Interactive (IP) Video: thru DOCSIS up to 150mbps/100mbps
Total pipe of 6Gbps of shared content
Voice + Data: Ride separate areas of Spectrum
xDSL (all IP solution):
ADSL2+: up to 25mbps bonded (total throughput actual)
VDSL: 25mbps (bonding still being developed)
PON (Mixed IP and RF solution):
GPON: up to 80mbps per user (avg based on 32 way split)
EPON: up to 30mbps per user ( “ “ )

Migrate DSLAM to 2-4Kft Drop
•
•
Upgrade of Existing ADSL to ADSL2+ Electronics
Migrate the DSLAM position deeper into the neighborhood

•
Increase subscriber throughput to 24 Mbps, add switched video
Creates Service Areas 60 – 400 HP, 200 HP Average
•
VDSL is being used for 35-40 Mbps requirements (Qwest) (up to
3kft) with pair-bonded ADSL2+ beyond 3kft
Pros
•
Estimated 25% HP within range - new equipment for rapid video
deployment
•
Minimizes new construction - approximately 10% of re-build
•
Standard telco technology - no craft training
Cons
•
Is 24 Mbps enough bandwidth to deliver a competitive video
offering?
•
Can 24 Mbps be achieved in real plant conditions?

Summary
•
•
•
Cisco has participated in a number of alternative access
technologies designed to offer triple-play solutions in the
marketplace.
Each technology has its own merits and must be chosen based on
the needs and existing network of a specific customer.
Active Ethernet provides the most flexible bandwidth option and is a
more cost-effective solution in a mostly MDU environment than
predicted in this model.
•
PON allows for optimized fiber usage in an upgrade scenario at the
expense of maximum flexibility and bandwidth capability.
•
xDSL provides the optimal solution for the Telco Service Providers
to leverage their infrastructure but comes with future scaling
questions.
•
HFC continues to be a cost-effective solution for Broadcast Video

DSL Architecture Trade-off: Distance &
BW limits vs. Growth
ADSL2 : 3 km service radius
ADSL2 : 3 km service radius
VDSL: 1.2 km service radius
VDSL requires ~ 7x fiber based node locations
BUT, 52 Mb would not meet long term needs if
triple play is the business plan goal
VDSL2: 0.3km service radius
VDSL2 requires ~ 40x fiber based node locations
At this point, FTTx is an incremental expense
For MUCH higher BW & flexibility

Telco Options:
Brownfield:
• Upgrade DSL technology to VDSL2
• Reduce copper distance to home by driving DSLAM’s
deeper in network
AT&T
Approach
• Pair-bonding doubles the data rate to home
• Begin upgrading to FTTH
Verizon
Approach
Greenfield:
• FTTH is the primary option they are considering
All Service Providers have similar challenges

Benefits of using a DOCSIS 3.0 CMTS to
deliver IP Video Services
•
Freedom to choose…
Codec, transport protocol, delivery method, control plane, and
end point for IP video services
•
Use all of your network all of the time
Dynamically allocate bandwidth based on business rules
•
Eliminate network silos
Avoid over-provisioning the network for each service
•
Improve efficiency and reduce costs for all
services
Increasing the CMTS capacity lowers the cost per bit

Admission Control
•
Ability to reserve set BW for video services per
interface
•
Ability to limit the flows that are admitted on an
interface based on set criteria
•
Admission Control is needed when bandwidth
utilization starts approaching interface bandwidth
•
Required for both multicast and unicast services
•
CMTS can perform Admission Control
Requires bandwidth requests to be signaled to the CMTS
73
CiscoEXPO

Adaptive Bit Rate Streaming
•
Stream is stored at various bitrates
•
Depending on bandwidth availability, stream of the
appropriate bitrate is streamed.
•
Stream is stored in small segments so that midsession the rate can be changed
•
Very popular for over-the-top delivery of video
•
With ABR is admission control no longer needed ?
No. It just means more streams can be packed before
admission control is needed.

Allows for best service velocity because legacy should not be
considered

Summary:
•
Video is critical for all Service Providers for increased
ARPU as well as maintaining their voice & data share
•
Telco SPs are deploying IPTV to differentiate from
Cable and offer interactive services.
•
Telco SPs are leading the charge in FTTH as they reassess their network needs.
•
Cable SPs have traditionally adopted a broadcast
DVB-C approach to video due to ease of deployment
and cost.
•
Cable SPs are also exploring IPTV solutions to
increase their content and customer reach.
All approaches are similar until the access layer.
Cisco can support you from end-end.

categorizes into popular and unpopular
• Unpopular content is NOT written to cache –
streamed from DRAM in “cut through” mode
• Only popular content written to cache

Influence of Caching Efficiency on Bandwidth Usage
A 5% difference in caching efficiency has significant cost implications
Houston Example
Cisco Field Performance
CRAN Gbps with Cache Efficiency
93% of traffic local
7% of traffic over backbone
Caching Efficiency
Based on 70K streams
Houston Site Streams
On average, less than 70% of an asset is viewed including trick files
Strategy: only cache what is needed at the edge, no more

Focus on the Edge
Motivations for Adaptive Bit-Rate Streaming
 Diverse Network Characteristics
– Dynamic Internet Conditions
– DSL vs. Cable vs. FTTH
– Home Network Contention
 Device Resources
– Processing Capabilities
– Display Resolutions
– Multi-tasking
 Improved Quality of User Experience
– Faster Start Time, Quicker Buffer Fills
– Minimizing Buffer under-runs: Skips, Stalls, Stutters
 Falling Costs of Storage
– Kryder’s Law/Moore’s Law
– Rise of new storage technologies – i.e. SSD
 SPs and CPs offering unmanaged services
– Public and SP CDN build-outs
– SPs can leverage same technology for managed
networks
