BriForum 2015 - Getting a Good Remote Experience on Today's Wi-Fi and Cellular Networks?

What Does It Take to Get a Good Remote Experience on Today's Wi-Fi and Cellular Networks?
Presented by Randy Groves

Remote desktops and applications require a highly interactive experience. Developing a solution that deals only with average packet loss and latency is not sufficient as there are finer details that reveal a more complicated and dynamic environment. The data at this finer level of detail is not generally available, so we developed an application for mobile clients that will send this information back to our database for further analysis. During this session, we present the results of measurements taken from real world situations, such as corporate Wi-Fi (with and without WMM), public and home Wi-Fi hot spots, and a variety of cellular use cases. We describe the various techniques of bandwidth estimation, congestion avoidance, and forward error correction, and explain how they can be used in these situations to provide the optimal user experience. We also show how protocols such as Citrix Framehawk and HP Velocity address these various scenarios. You will gain:

  • An understanding of the characteristics of many Wi-Fi and cellular scenarios and their impact on remote User experience
  • Techniques that protocols use to maximize experience and conceal packet loss, all while being fair to other users of the same network
  • An understanding of which scenarios these techniques will be effective in improving user experience and when they will not
  • Examination of benchmark data on how current protocol behave under these real world conditions

Session Takeaway: Learn ways to improve remote user experience for Wi-Fi and cellular-connected devices and examine how current technologies do/do not address the various scenarios. Walk away with a solid understanding of the basics of bandwidth estimation, congestion avoidance, and forward error correction.
