Design and implementation of a production dynamically configurable testbed

Production quality high speed networks connecting end devices are needed to design and prototype new types of distributed applications. The eaviv testbed has been de-ployed to provide such a facility, connecting Louisiana State University, National Center for Supercomputing Applications and Masaryk University, and enabling ser-vices for dynamic provisioning of dedicated bandwidth via Internet2 ION. This paper includes technical chal-lenges and solutions in deploying eaviv such as dealing with multiple administrative domains, network address-ing, and end-to-end connectivity. These issues apply not only to temporary testbeds, but also to networks which facilitate long-running experiments and research and whose infrastructure is global and at least partially dynamic.
