Packet loss is a major problem for real-time Internet applications.
Markov models of packet loss 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.
We introduce a new type of model, incorporating packet delay
information, and show improved accuracy over previous models.
