Abstract--An analytical framework for modeling the performance of a
single TCP session in the presence of random packet loss is presented. A
Markovian approach is developed that allows us to study both memoryless
channels (i.i.d packet loss) and channels with memory (correlated packet
loss) modeled by a two state continuous time Gilbert model. The analytical
results are validated against results using the ns simulator. It is shown that
the model predicts throughput for LANs/WANs (low and high bandwidth-
delay products) with good accuracy. Further, throughput for the i.i.d loss
model is found to be relatively insensitive to the probability density func-
tion (p.d.f) of the loss inter-arrival process. For channels with memory, we
present an empirically validated rule of thumb to categorize the channel
transition frequency.
Keywords--Transport control protocol, wireless networks, performance
analysis.
