Abstract: Scientific computations and collaborations increasingly rely on the network to provide high-speed data transfer, dissemination of results, access to instruments, support for computational steering, etc. The Energy Sciences Network is establishing a science data network to provide user driven bandwidth allocation. In a shared network environment, some reservations may not be granted due to the lack of available bandwidth on any single path. In many cases, the available bandwidth across multiple paths would be sufficient to grant the reservation. In this paper we investigate how to utilise the available bandwidth across multiple paths in the case of bulk data transfer.

Keywords: bulk data transfer; performance measurement; performance improvement; user driven bandwidth allocation; bandwidth reservation; traffic engineering; overlay networks; high-speed data transfer; science data network.
