| Discussion Topic #1: Methods of getting user input (45 min) (Moderator: Peter Dinda) | |
| Discuss and review the range of options today for getting input from users of networked applications. What other new options are potentially available to us? Can traditional HCI methods be adapted for networked-applications? What roadblocks prevent us from getting large-scale user sampling data? How can we incentivize users to provide more data? | |
| 12:30pm - 2:00pm | Lunch |
| 2:00 - 3:30pm | Session #3: Correlating Lower Layer Measurements with User Perception (Chair: David Wetherall) |
| Inferring the QoE of HTTP Video Streaming from User-Viewing Activities (15 min) | |
| Ricky K. P. Mok, Edmond W. W. Chan, Xiapu Luo, Rocky K. C. Chang (Hong Kong Polytechnic University) | |
| Performance of Networked Applications: The Challenges in Capturing the User's Perception (15 min) | |
| Diana Joumblatt (CNRS and UPCS Sorbonne Universites), Renata Teixeira (CNRS and UPMC Sorbonne Universities), Jaideep Chandrashekar (Technicolor Labs), Nina Taft (Technicolor Labs) | |
| Understanding End-user Perception of Network Problems (15 min) | |
| J. Scott Miller, Amit Mondal, Rahul Potharaju, Peter Dinda, Aleksandar Kuzmanovic (Northwestern University) | |
| Discussion Topic #2: Issues in reconciling data across layers (45 min) (Moderator: Nina Taft) | |
| What is the right granularity or service to apply QoS ? Users perceive "quality" (QoE) as relating to high level concepts such as "shopping", or "video", whereas networking researchers think of QoS as it relates to particular protocols. How can we reconcile this? Annotating lower layer measurements with user feedback constitutes 'data labeling'. How much of the 'labeling' procedure can we automate? How do we manage the mismatch in the volume of data collected at these different layers? | |
| 3:30pm - 4:00pm | Break |

| Zachary S. Bischof (Northwestern University), John S. Otto (Northwestern University), Mario A. Sanchez (Northwestern University), John P. Rula (Northwestern University), David R. Choffnes (University of Washington), Fabián E. Bustamante (Northwestern University) | |
| Discussion Topic #3: Measuring user-facing properties of networked applications (45 min) (Moderator: David Choffnes) | |
| How do we best measure user-facing properties such as responsiveness, e.g., page load times instead of HTTP transaction latencies? Low-level measurements such as network traces often do not translate directly into user-facing actions, which suggests application-level measurements. Can we come up with general application-level measurement strategies, or must each application be measured differently? Should application-level concepts (like foreground or background operation) be embedded into lower level messages to make tracing applications easy? | |
