Studies report that in North America video now accounts for 40-66% of all traffic on the Internet and it will rapidly increase to 90-95%. Internet video services are now using the same methods to deliver video to consumers as are used to deliver data from web searching, banking, on-line shopping, social networking and other popular services. The problem is that the existing systems used to deliver that content have not been designed and optimized to deliver video. The result is often a less than satisfying video viewing experience, with videos being interrupted or paused while the video is fetched from the server. This can be especially noticeable when trying to view high-definition videos or during times when others are using the same service or network. More importantly, there is evidence that shows that as the demand for video increases, it will make the existing services we have come to rely on slower and slower. Our research will devise new methods to improve the efficiency of the underlying systems software and networks used to deliver content to consumers. We will experimentally evaluate, identify bottlenecks in, and improve the performance of existing software systems. This will reduce the number of machines required by providers of Internet services, thereby reducing the power they consume and lowering their costs. For consumers this should reduce costs paid for these services. In addition, this will enable the smooth delivery of high-quality video to their desktop PC, laptop, netbook, tablet or smart phone whether they are at work, home, or on the road. Most importantly, we will make these improvements while ensuring that existing services that have become critical to our lives not only continue to function but function well.

研究报告称，在北美，视频目前占互联网所有流量的40-66%，并将迅速增加到90-95%。互联网视频服务现在使用与网络搜索、银行、网上购物、社交网络和其他流行服务中传输数据相同的方法向消费者传输视频。问题在于，现有的用于传送内容的系统并没有经过设计和优化来传送视频。结果往往是一个不太令人满意的视频观看体验，视频被中断或暂停，而视频从服务器获取。这在观看高清视频或其他人使用相同服务或网络时尤其明显。更重要的是，有证据表明，随着视频需求的增长，我们所依赖的现有服务将变得越来越慢。
