Abstract: {N}etwork latency and packet loss are considered to be an important requirement for realistic evaluation of {P}eer-to-{P}eer protocols. {D}edicated clusters, such as {G}rid'5000, do not provide the variety of network latency and packet loss rates that can be found in the {I}nternet. {H}owever, compared to the experiments performed on testbeds such as {P}lanet{L}ab, the experiments performed on dedicated clusters are reproducible, as the computational resources are not shared. {I}n this paper, we perform experiments to study the impact of network latency and packet loss on the time required to download a file using {B}it{T}orrent. {I}n our experiments, we observe a less than 15% increase on the time required to download a file when we increase the round-trip time between any two peers, from 0 ms to 400 ms, and the packet loss rate, from 0% to 5%. {O}ur main conclusion is that the underlying network latency and packet loss have a marginal impact on the time required to download a file using {B}it{T}orrent. {H}ence, dedicated clusters such as {G}rid'5000 can be safely used to perform realistic and reproducible {B}it{T}orrent experiments.
