Keynote Address

It's Not the Cost, It's the Quality!
Ion Stoica, University of California, Berkeley

View the presentation slides

In this talk, I will discuss some of the challenges and opportunities faced by streaming video over the Internet. First, I would argue that for premium content reducing the distribution cost is no longer the main challenge. To large extent, this is due to the rapid decrease of the CDN costs, and the emergence of the HTTP chunking technologies. Next, I'll show that the quality of video streaming has a significant impact on the video engagement, and by extension on the content provider's revenue. Finally, I will show that the quality problem is not fully solved by today's CDNs, and argue that it is an opportunity for the p2p community to step up and address this problem.

Invited Talk

Telling Time
Bram Cohen and Arvid Norberg, BitTorrent

View the presentation slides

A completely synchronized clock which gives the same time everywhere does not exist. We will explain the problems this causes for measuring delays, and discuss techniques for dealing with those problems used in utp, including a new technique for canceling out clock drift.

5:30 p.m.–6:00 p.m.

Closing Address

Backend Consistency for Large-Scale Live Services
Dahlia Malkhi, Microsoft Research

Companies that build large live cloud service face daunting scalability and availability requirements. Often, these are met at the expense of consistency, e.g., allowing shopping carts to lose items (oh well), or for web search to return stale results (oh well). These solutions fail to meet today's advanced cloud services, for which consistency is a must. For example, Microsoft SQL Azure provides live relational DB services from a cloud. Microsoft FAST Search Server provides indexing and search hosting services for enterprises. In both, clients benefit from quick deployment and transparent management by a cloud which is provisioned and managed by with the highest assurance.

The backend systems supporting these live services guarantee strict data consistency while maintaining scalability, high availability, and failure handling. The talk reviews lessons taken from the innovative architectures and algorithms designed to meet the extreme requirements of these large live data services
