Gaedtke IV

Jason Gaedtke, Director of Engineering, YouTube

Abstract: According to industry reports, IP video currently makes up more than half of the Internet’s bandwidth. The infrastructure and network relationships assembled to deliver this volume are complex — cloud processing and storage, distributed file systems, hierarchical caching layers, transit networks, direct peering, embedded ISP nodes and intelligent player control. This talk will explain how YouTube’s investment in video QoE is key to delivering 1 billion users over 6 billion hours of fast, reliable streams each month and how focusing on QoE will help guide the next phase of Internet growth.
