Management of multidomain end-to-end links - a federated approach for the pan-European research network Geant 2

Modern large-scale research projects require a tight international cooperation and have exceeding network bandwidth demands. Dedicated optical multi gigabit End-to-End (E2E) Links offer a possible way to meet these requirements. These links generally are realized with layer 1 and 2 technologies and cross multiple networks operated by different organisational domains. The federated organisation of the operation and the usage of heterogeneous hardware applying a variety of information access and management techniques require a new approach for the management of these multidomain E2E Links. This paper gives an overview about the organisational and technical challenges of E2E Link operations and shows the elaborated solution as well as intermediate results of the ongoing work within the pan-European research network Geant2.
