-------------------------
We provide a case study of current inefficiencies in how traffic
to well-known cloud-storage providers (e.g., Dropbox, Google Drive,
Microsoft OneDrive) can vary significantly in throughput (e.g., a
factor of 5 or more) depending on the location of the source and
sink of the data. Our case study supplements previous work on
resilient overlay networks (RON) and other ideas.
These inefficiencies exist in the presence of vendor-specific
points-of-presence (POP), which try to provide better network
performance to the clients. In fact, the existence of special-purpose
networks (e.g., national research networks, PlanetLab) and complicated
peering relationships between networks, means that performance
problems might exist in many wide-area networks (WANs).
Our main contribution is to continue the cataloging of network
inefficiencies so that practitioners and experimenters are aware
of them. But, we also show how simple routing detours, can improve
throughput by factors of over 3x for client-to-cloud-storage.
Cut-through routing technique can increase the effective throughput
further. Although the specific inefficiencies in this paper might
be transitory (and we agree with that characterization), WAN
bottlenecks due to routing, suboptimal middlebox configuration, and
congestion persist as real problems to be cataloged, discussed, and
addressed through the use of detours, or data transfer nodes (DTNs),
or RONs.
