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.
