This project aimed to develop strategies for scaling up the service components (based on original ODL components) using cluster computing. Components were modified and inserted into a lightweight framework that supported migration to idle machines or replication to meet service demands. This showed the minimum set of services necessary to support such functionality - in contrast to commodity grid installations.
