title: Redundant Bundling in TCP to Reduce Perceived  Latency for Time-Dependent Thin Streams
publication_year: 2008
abstract: TCP and UDP are the dominant transport protocols today, with TCP being preferred because of the lack of fairness mechanisms in UDP. Some time-dependent applications with small bandwidth  requirements, however, occationally suffer from unnecessarily  high latency due to TCP retransmission mechanisms that are  optimized for high-throughput streams. Examples of such  thin-stream  applications are Internet telephony and multiplayer  games. For such interactive applications, the high delays can be  devastating to the experience of the service. To address the latency issues, we explored application-transparent,  sender-side modifications. We investigated whether it is possible  to bundle unacknowledged data to preempt the experience of packet  loss and improve the perceived latency in time-dependent systems.  We implemented and tested this idea in Linux. Our results show that we can reduce the application latency by trading it against bandwidth.
