A series of bandwidth tests have been performed using the existing production network in order to understand baseline performance capabilities as well as confirming the impact that large file transfers have on the network.

It was assumed that a 10G connected server would not be able to impact the core 20G Duke network.  However, we have seen multiple impacts on the Duke network due to baseline testing for this project.

perfSONAR tests have been shown to be NON intrusive, but large, dedicated load cannons that do sustained file transfers have highlighted capacity issues in the core Duke academic campus network.
