Dynamic Transport Enhancement for Time Elastic Traffic with Transientware
Javed Khan, Raid Y. Zaghal, Qiong Gu · 2003
The paper presents the concept of transientware---a mechanism by which sensitive applications can launch application level targeted and dynamically adaptive enhancements of transport service. The proposed transientware can be used with current transport protocols with interactivity enhancement. As a proof of concept we have recently designed and implemented a functionally enriched transientware enabled TCP on FreeBSD Unix. We then show the performance of a TCP friendly adaptive MPEG-2 video transcoder, which can directly interact with this transport and adjust its outgoing video rate to satisfy temporal quality constraint of the stream via a dynamic rate adaptive scheme. We report potential dramatic improvement in time-bounded video delivery of elastic traffic from live experiment.
