Abstract: Real-Time Communication (RTC) applications are on the rise. Skype, a popular application for VoIP, video conferencing, file sharing and instant messaging, is growing at a rapid pace. Skype users have logged 115 billion minutes in the quarter of July 2012, which is up 50 percent compared to the prior quarter and represents about one fifth of the world long distance calls. 43% of Skype-to-Skype calls involve video. RemoteFX, a key feature in Windows 8, is revolutionize desktop virtualization, and enables unprecedented Cloud Computing experience. Quality of Service has proven to be critical for the commercial success and the customer satisfaction of the RTC applications. In this talk, we will discuss a number of client and platform technologies that improve the Quality of Service of RTC applications. This will include: 1) the use of forward error correction (FEC) in RTC applications, 2) bandwidth management, and 3) quality of service monitoring platforms. Bio: Dr. Jin Li is a Research Manager and Principal Researcher at Microsoft Research (Redmond, WA). He manages the Compression, Communication and Storage group.
