04/29/10 Need to precisely quantify performance during the buffering period Synching up application and network level measurements is a challenge (even on one host) We came up with a way to parse RTSP packets and application level data to do so. Point out: 1) buffering (loss 2) Not TCP-friendly 3) Responsive to capacity --- NOT FIREHOSE CBR 4) Depends on the encoding rate vs. the capacity (lots of burden on content provider)
