ExoGENI is a GENI testbed that links GENI to two advances in virtual infrastructure services outside of GENI: open cloud computing (OpenStack) and dynamic circuit fabrics. ExoGENI orchestrates a federation of independent cloud sites located across the US and rest of the world, of which UvA is one of them.

ExoGENI is, in effect, a widely distributed networked infrastructure-as-a-service (NIaaS) platform geared towards experimentation and computational tasks. ExoGENI employs sophisticated topology embedding algorithms that take advantage of semantic resource descriptions using NDL-OWL – a variant of Network Description Language.

Individual ExoGENI deployments consist of cloud site “racks” on host campuses, linked with national research networks through programmable exchange points. The ExoGENI sites and control software are enabled for flexible networking operations using traditional VLAN-based switching and OpenFlow. Using ORCA (Open Resource Control Architecture) control framework software, ExoGENI offers a powerful unified hosting platform for deeply networked, multi-domain, multi-site cloud applications. We intend that ExoGENI will seed a larger, evolving platform linking other third- party cloud sites, transport networks, and other infrastructure services, and that it will enable real-world deployment of innovative distributed services and new visions of a Future Internet.


OpenLab is a facility that provides an open experimentation environment for Software Defined Networking (SDN) research. OpenLab is hosted by the Systems and Networking (SNE) Lab at the Informatics Institute of the University of Amsterdam.

OpenLab currently consists of an ExoGENI Rack, multiple XenServer virtualisation servers, an OpenFlow testbed and various server and switching hardware for experiment purposes. HPC Fund and Ciena contributed to OpenLab.

Available for a large community

A large community outside the Informatics Institute uses OpenLab. Frequent users of the lab are for example the national research community (SURFnet GigaPort Research on Network project); eScience center (Astronomy); Faculty of Science research cluster I4DW (Informatics for a Data Rich World); Florida International University and University of Chicago; international CineGrid community (Waag, NFA, UCSD, NPS); international networking NREN community (GLIF SURFnet and GN3+  on 100gbps research); and UvA/VU COMMIT-projects.

SNE Lab welcomes students and researchers that would like to use OpenLab: How to use the ExoGENI UvA rack?
