Modelling Packet Loss in RTP-based Streaming Video for Residential Users
Martin Ellis will present our paper on Modelling Packet Loss in RTP-based Streaming Video for Residential Users at the the IEEE Conference on Local Computer Networks in Clearwater, FL, USA, on 23 October 2012.
The abstract of the paper reads:
Packet loss is a major problem for real-time Internet applications, such as telephony, video conferencing and IPTV systems. Markov models of packet loss, such as the Gilbert-Elliott model, are often used to develop and evaluate the performance of these applications. Despite their wide use, these models have not been validated in terms of how well they capture the loss conditions experienced by residential Internet users. We evaluate the accuracy of common packet loss models using traces of IPTV-like traffic measured on residential ADSL and Cable links, and find that these models are insufficient to capture the observed packet loss patterns. In this paper, we introduce a new two-level Markov model, incorporating packet delay information, and show improved accuracy over previous models.
