© Velocix All Rights Reserved.4 Combining CDN and P2P Technologies Velocix makes use of several technologies that were first widely used in P2P clients: Multi-source o Data is received from several sources simultaneously. o Provides increase throughput compared to single source o Adds resilience as reliance on single connection removed o Enables dynamic blending of bandwidth to minimise delivery costs o Copes with change in network conditions by altering sources dynamically Peer delivery o Data can be shared amongst users, as well as delivered from caches o Reduces overall delivery cost o Adds further resilience as number of sources increases Integrity checking o Errors are detected at the piece level and corrected Resumable downloads o As the file is broken into pieces the download is treated as a series of discrete transfers o If a download is interrupted it will resume from the last complete piece, rather than starting from the beginning These technologies are used to improve quality and reliability within the Velocix network and are available over appropriate delivery protocols.

Lets start by comparing single source downloads vs P2P downloads Server – normally sent at required rate, but since it is served from a single server, it all needs to be served from a nearby server P2P – normally doesnt provide good enough speed

P2P provides as much bandwidth as it can Expensive cache steps in smoothes off the transfer Higher cost cache steps in and supplies most of shortfall at other times Low cost cache steps in first and supplies most of shortfall most of the time The lower the target speed the cheaper the delivery

CacheLogic Advanced Solutions for P2P Networks DCIA P2P Media Summit | P2P File Sharing - The Evolving Distribution Chain Peer-to-Peer Today In the last seven years P2P has grown to dominate Internet traffic More than 60% of consumer Internet traffic is P2P P2P saturates ISP networks Downstream: 50-65% Upstream: 70-80% More than 60% of P2P is video P2P files are massive Globally: >50% >1GB Asia: >50% >2.5GB

CacheLogic Advanced Solutions for P2P Networks DCIA P2P Media Summit | P2P File Sharing - The Evolving Distribution Chain Internet-Based Content Distribution is Evolving Commercial distribution of music over the Internet becomes mainstream By the beginning of 2005, UK online single sales overtook CD single sales(1) By the end of 2005, 20M tracks per week being bought online worldwide. And sales of MP3 players had overtaken that of CD players(2) US physical media sales fell by 8-10% on 2005, where as online sales grew by between %(3) Commercial trials of Broadcast/DVD quality P2P video BBC iMP ntl Warner Bros Initial commercial P2P video trials AOL Sky Rollout of commercial P2P broadcast quality video services Consumer Produced Video Google Youtube Portable Video iTunes

© Velocix All Rights Reserved.13 What went wrong? P2P video distribution was dominating consumer Internet traffic But the transition to commercial delivery using P2P was complicated by: DRM falling out of favour stalled download market Client deployment concerns Flash plugin enables custom player UI without user permission Advertising funded free-to-use Web 2.0 Success of progressive download and streaming services o Youtube o Hulu, BBC iPlayer, etc. Mass market reluctance to wait for non-free content Lack of compelling content on P2P TV services Wholesale bandwidth costs dropped Wholesale digital video content pricing Influx of suppliers in traditional CDN space reduced delivery costs

© Velocix All Rights Reserved.14 So where does P2P fit in 2009? Delivery methods: P2P – most bytes transmitted by other clients – market limited by asymmetric broadband access (DOCSIS/DSL) Single Source – bytes transmitted from a single server typically HTTP or streaming – classic CDN Multi Source – bytes transmitted from a combination of servers and (optionally) clients) – hybrid CDN

© Velocix All Rights Reserved.15 P2P Content Delivery Future Current opportunity limited by Falling CDN pricing CDNs keeping with up traffic volumes Over supply in market DRM/CA replaced by streaming Indicators for future opportunity Symmetric broadband access Effective DRM/CA Adaptive codecs TV with integrated Internet High capacity flash storage Standardisation o P4P a good start o Need standardisation in the system architecture and inter-component communication

© Velocix All Rights Reserved.16 Whats the role of Velocix in all of this?
