Research Topic • Massive Wave of Internet Traffic • 90% of all Internet bits by 2010 • How will Video Service Providers distribute this massive amount of Video Traffic over the Internet?
Modeling the Video Service Provider Distribution Networks Four Models • Commodity Transit • CDN • Transit/Peering/DIY CDN • Peer2Peer Four Load Models A: Small Load B: Medium Load C: Large Load
Load Model A • Load Model A – Light Load: Every 5 minutes, 10 customers each start to download a 1.5 GB movie, resulting in an average 15GB five minute load. Adjust load to sinusoidal customer traffic demand curve Jeff Turner: 6.6:1 peak-to-mean
Load Model B • Load Model B – Medium Load: Every 5 minutes, 100 customers each start to download a 1.5 GB movie, resulting in an average 150GB five minute load. Adjust load to sinusoidal customer traffic demand curve Jeff Turner: 6.6:1 peak-to-mean
Load Model C • Load Model C – Large Load: Every 5 minutes, 1000 customers each start to download a 1.5 GB movie, resulting in an average 1500GB five minute load. Adjust load to sinusoidal customer traffic demand curve Jeff Turner: 6.6:1 peak-to-mean
Assumptions • 1000 full length 1.5GB videos • Equipment Costs • Transit Costs • Colo Costs • Staff Costs • Software=LAMP • Colo@IX • Multi-homed
Model 1: Commodity Transit Business Premise: • VSP focuses on core competence • Transit Providers handle traffic better and cheaper • Economies of scale, Aggregation, Expertise, Billing, Peering, etc.

Model 2: Content Delivery Networks (CDNs) for the Distribution of Video Content • Business Premise: Single-site transit traffic traverses potentially many network devices, increasing latency and the potential of packet loss: • By spreading web objects closer to the eyeball networks latency is reduced • Fewer network elements are traversed so reliability is improved • Congestion points in the core of the Internet are avoided • CDNs have the expertise, deployed infrastructure, economies of scale from aggregation efficiencies.
Model 3: Transit/Peering/DIY CDN • Business Model Premise: Operation of the Internet distribution is seen as strategic to the VSP: • End-user experience is mission-critical so outsourcing the end user experience to a transit provider or CDN puts the VSP at risk. • The VSP has visibility into what video are being released, which ones are likely to be hot and which ones don’t require special infrastructure adjustments. • Internet Video distribution is so new that the VSP prefers control. This is a strategic focus of the VSP: ensuring reliability, scalability, through the constant monitoring and evolution of the infrastructure to ensure the end user experiences during these early phases of Internet Video Distribution. • The traditional CDN may be ill-suited to distribute very large video object, therefore we have to do it yourself.
Model 4: Peer2Peer • Business Model Premise: The current Internet Service Providers and CDNs at the core can not handle the load across single or even multiple locations: • Backbone, peering interconnects, and the hundreds of thousands of routers deployed can not handle the load of today and tomorrows video. • the leaf nodes (i.e. Grandma’s PCs left on) in aggregate have the cycles and network capacity, if shared, to distribute popular content today. • Popular content can be chopped up into small chunks such that many downloaders become sources, and topologically close downloaders will prefer the topologically close sources. This ‘swarmcasting’ requires only a source ‘seed’, and a lookup mechanism for the first downloaders to find the seed, and then to direct future downloaders to topologically closer sources.
