An Improved Timer Scheme of Multiple Retransmissions for Media Streaming

Abstract

Sender’s retransmission for the lost packet to receiver is a popular error control scheme in public network due to its cost effectiveness. However, either the ARQ(Automatic Repeat reQuest) or the retransmitted packet may be lost again. Multiple retransmissions for a lost packet are possible while the receiver’s processing deadline of the lost packet is larger than the network round trip delay (i.e. RTD). In this paper, we improve the traditional timer scheme# to effectively detect the loss of ARQ or retransmitted packet to furnish the multiple retransmissions. Moreover, we demonstrate that our improved timer scheme for multiple retransmissions can effectively reduce the packet loss ratio by the performance results from not only simulations, but also a True VOD system.
