Efficient mechanisms for recovering voice packets in the Internet
Daniel R. Figueiredo, Edmundo de Souza e Silva · 2003
Multimedia applications, such as voice transmission, have increasingly been used over the Internet. However, there are still many issues under investigation, related to the quality of audio delivered, such as the reduction of the jitter and the loss of audio packets. Concerning audio packet loss, many recovery mechanisms have been proposed to improve the audio quality. However, the efficiency of these mechanisms is largely dependent on the loss process in the network. In this paper we study the packet loss process of audio streams aiming at comparing different recovery mechanisms. We also propose a new packet recovery mechanism and show that its efficiency can be significantly better than others proposed in the literature.
