The project will build and deploy SCAFFOLD (Service-Centric Architecture For Flexible Object Localization and Distribution), a platform for designing and operating wide-area distributed services on GENI. SCAFFOLD will be a distributed service on GENI that serves as a platform for deploying user-facing services, thereby lowering the barrier for others creating new distributed services. SCAFFOLD will leverage GENI-related prototyping efforts such as OpenFlow switches, the NOX controller, the VINI backbone, the BGP multiplexer and the PlanetLab control framework. The project will use SCAFFOLD to build three services for GENI: A reliable DNS, a port of CoralCDN and a Flash-based video-on-demand service.
