- Filter out very old packets (to ensure that the estimate doesn't drop to zero if sending is paused and later resumed). - Discard packets older than previously discarded packets (to avoid the estimate dropping after deep reordering.) - Add tests cases for high loss, deep reordering and paused/resumed streams to unittest. - Remove some field trial settings that have very minor effect and rename some of the others. - Change analyzer.cc to only draw data points if the estimators have valid estimates.
