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 deployed to provide such a facility, connecting Louisiana State University, National Center for Supercomputing Applications and Masaryk University, and enabling services for dynamic provisioning of dedicated bandwidth via Internet2 ION. This paper includes technical challenges and solutions in deploying eaviv such as dealing with multiple administrative domains, network addressing, 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.
