Inside iRODS, we'll use the iRODS web browser to visualize the results of our experiment. 29 30 The measurement database is organized as a series of key-value-wrid triples. Each {{{key}}} defines a kind of measurement (e.g., RTT or estimated available bandwidth) and each {{{wrid}}} defines a measurement source (e.g., video sender, audio receiver, bandwidth estimator). 31 32 To visualize these measurements, we'll open the {{{sq3}}} file from our experiment in iRODS and click on the '''plot''' tab. From here, we'll be able to set up our visualization. 33 34 For example, we can create the following plot, which shows the round trip time in milliseconds measured by WebRTC: 29 35 30 36 31 Inside iRODS, we'll use the iRODS web browser to visualize the results of our experiment. 37 || [[Image(googRtt.png,100%)]][[BR]]Setting up plot||[[Image(googRttPlot.png,100%)]][[BR]]Finished visualization || 38 39 There are many other metrics available - try plotting with the following keys: 40 * googFrameRateSent 41 * googFrameRateReceived 42 * googJitterReceived 43 * packetsLost 44 * googAvailableReceiveBandwidth 45 * googAvailableSendBandwidth 46 * googTransmitBitrate 32 47 33 48 == Reconfiguring the WiMAX BS == … … 41 56 }}} 42 57 43 From there, you can change base station settings using a simple HTTP interface.
