Abstract

This article evaluates the maximum data flow from a sender to a receiver via the internet when all transmissions are scheduled for early morning hours. The significance of early morning hours is that internet congestion is low while users sleep. When the sender and receiver lie in proximal time zones, a direct transmission from sender to receiver can be scheduled for early morning hours. When the sender and receiver are separated by several time zones such that their sleep times are non-overlapping, data can still be transmitted during early morning hours with an indirect store-and-forward transfer. The data are transmitted from the sender to intermediate end networks or data centers that serve as storage hops en route to receiver. The storage hops are placed in zones that are time proximal to the sender or the receiver so that all transmissions to and from storage hops occur during low-congestion early morning hours. This article finds the optimal locations and bandwidth distributions of storage hops for maximum nice internet flow from a sender to a receiver.

On the dynamics of valley times and its application to bulk-transfer scheduling

“…Finally, another option is to identify those periods when a network is in a low-use state, for example at early mornings. As already introduced, the authors in [12,25] identified the interval between 3 and 6 a.m. as appropriate for undertaking backups. Similarly, Netflix suggests the interval from 2 a.m. to 2 p.m. to perform content-distribution tasks.…”
