Video Content Networking Does it Scale? GPF 2.0 March 2007 Martin J. Levy– Moderator Patrick Gilmore– Akamai Brokaw Price– Yahoo Guy Tal– Limelight Networks

Introductions Martin J. Levy ◦ UnitedLayer – Co-location and bandwidth Patrick Gilmore ◦ Akamai – CDN Brokaw Price ◦ Yahoo – Portal & Content provider Guy Tal ◦ Limelight Networks – CDN

Moderated Q&A Session Why is video traffic so different than non- video traffic? ◦ Streaming vs. non-streaming content ◦ Time-of-day viewing habits ◦ Bandwidth & transfer size per transaction ◦ Crowd-effect vs. bandwidth peaks ◦ Single vs. Distributed location for source

Moderated Q&A Session Handling larger bandwidths ◦ Must you geographically distribute the content for every piece of source material? ◦ Can you mix video with non-video traffic? ◦ Do peering or transit interconnections at 1Gbps/10Gbps speeds make sense vs. ISP’s actual backbone size? ◦ Does GLB (global load balancing) work in all cases?

Moderated Q&A Session Co-location & exchange points ◦ Are any of the providers of exchange points offering special services for video providers? ◦ Do exchanges provide the appropriate space (or power) for video source hardware? ◦ Is it fair for a video provider to “suck-up” all the power in exchanges? (or should exchanges prioritize usage of power?)

Moderated Q&A Session Capacity management ◦ Last-mile bandwidth, is there any? ◦ Multicast – “discuss amongst yourself”  Gridcast/Peer-to-peer/etc. ◦ Do new boxes (AppleTV, TiVo, Media Servers, etc.) change ISP’s bandwidth patterns because of continuous background downloads? ◦ Is it the responsibility of the ISP to handle event driven bandwidth or just let it suck?

Moderated Q&A Session Emerging technologies ◦ Are there any?
