The Application Quadrant presented by Mu
Dynamics is based on research into the runtime
aspects of the most popular desktop
video applications (Netflix, YouTube, Hulu,
Amazon Video on Demand). It compares them
against each other in both Standard Definition
(SD) and High Definition (HD) formats across
two dimensions:

Mu App Quadrant Report April 2011

  1. 1. REPORTMu Application Quadrant:Understanding the Impact of Video Applications on Consumers & Network OperatorsIntroductionOver the last 12 months, video consumption has skyrocketed. According to Nielsen, Netflix alone now accounts for 20% ofdownstream traffic during peak times in the United States.Video has become the killer app for consumers and businesses alike.The Application Quadrant presented by MuDynamics is based on research into the run-time aspects of the most popular desktop Video Applications – High Definitionvideo applications (Netflix, YouTube, Hulu,Amazon Video on Demand). It compares themagainst each other in both Standard Definition More Consumer-Friendly -(SD) and High Definition (HD) formats across (Less Verbose)two dimensions: • Consumer-friendliness: The less bandwidth an application consumes, the more Consumer-friendly it is, especially as new usage-based pricing models are introduced. More Operator-Friendly - (Less Chatty) • Operator-friendliness: The fewer connections established by an application within a given session, the more Operator-friendly it is as less resources are consumed across the network.Key FindingsThe following findings were observed: 1. Relative to the other video Video Applications – Standard Definition applications: a. Netflix is less friendly to Consumers More Consumer-Friendly - in both SD and HD. (Less Verbose) b. YouTube is a friendly application for Operators and Consumers in both SD and HD. c. Hulu is the least Operator-friendly in both SD and HD. d. Amazon HD is more Operator- friendly than SD. 2. SD video is 30% more Consumer- friendly than HD but actually slightly less Operator-friendly. More Operator-Friendly - (Less Chatty)* Graph axes show % from mean on each dimension
  2. 2. The Real Breakthrough in TestingMethodology Bandwidth ConsumedAll comparisons were based on multiplemeasurements. We took several samples ofeach application for significant durations fromthe same client, and in similar local networkconditions. For these samples we ran queriesto extract data regarding flows and connectionsper second as well as data transfer rates (bytesper second). Finally we normalized the data ineach group (SD and HD) to establish a common bytes/secscale. For example, all the HD data points for thex-axis (connection rate) and the y-axis (bytes/second) were averaged to yield the x-avg andy-avg for that group. Then for each applicationthe percentage difference from the average wasplotted on a scale that had x-avg and y-avg as(0,0).What’s Next?The next Mu Application Quadrant Report will Connection Rateshow the impact of different mobile devices(iPhone, Android phone, etc.) on the network. connections/secAbout Mu DynamicsMu Dynamics is the leader and pioneer intesting and validating application-awarenetworks.
