Abstract:
We study the running time of distributed algorithms deployed in a
widely distributed setting over the Internet using TCP. We consider a
simple primitive that corresponds to a communication round in
which every host sends information to every other host; this primitive
occurs in numerous distributed algorithms. We experiment with four
algorithms that typically implement this primitive. We run our
experiments on ten hosts at geographically disperse locations over the
Internet. We observe that message loss has a large impact on algorithm
running times, which causes leader-based algorithms to usually
outperform decentralized ones.
