Abstract
A Detailed Analysis of Different Strategies
- Detailed Network Model
- Contention Ratio: Internet Television
- Hosted, P2P and Hybrid Approaches
- Comparative Cost Analysis
- Transit & Peering Agreements
- Advanced P2P Strategies
The report clearly illustrates the problems of distributing legitimate video
content on a mass scale over the internet and offers a roadmap for addressing
those problems.
The report analyses the cost implications of four alternative video content distribution strategies which are:
- (1) Hosted, no local cache (parasitic transit & paid-for transit);
- (2) Hosted, local caches;
- (3) Hybrid (P2P and local caches) and,
- (4) Network Aware, Pure P2P.
The report first explains the cost and performance implications of delivering
video traffic over the internet. Peering and transit relationships are then
explained so that the cost implications of sending large volumes of internet
video traffic between internet networks can be quantified.
The report then describes a detailed network model that has been used to
analyse each of the four content distribution strategies. The model includes
9.25 million homes, two markets, three ISPs, one internet television service
provider, two transit networks and two internet exchange points.
The report then analyses the contention ratio that is applicable for internet
television, which is dramatically different to the 30:1 that has been
historically used by ISPs.
In each of the next four sections the report includes a network architecture
diagram, numerous tables and a clear explanation of how the video traffic
flows around the five networks used in the model. The cost implications of
adding content servers and delivering traffic between networks are clearly
defined.
The final part of the report contains a comparison table that offers an
‘at a glance' comparison of the cost implications of the four different
content distribution strategies on ISPs and the internet television service
provider.
Key Benefits
- Appreciate why free distribution is not a sustainable proposition.
- Discover the true costs of distributing video content and factor those
costs into your business and product plans.
- Understand how ISPs can develop their networks using approaches that
embrace P2P concepts, rather than just adding more core network capacity.
- Clearly understand the cost implications of different content distribution
strategies.
- Dramatically improve your understanding of how the internet is being used
to distribute digital content.
