Project Title

Prototype Support for Heterogenous Testbed Resources: Integrating cluster, broadband, and wireless emulation nodes into the “Proto- GENI” Framework
a.k.a. CMU Testbeds, CMU Homenet (obsolete), CMULab, CMULAB

This project will build upon CMU’s existing cluster, neighborhood wireless/broad-band, and wireless emulation testbeds to concretely identify—and build prototypes of—the authentication, resource arbitration, and node management primitives needed to coherently deal with this very diverse set of resources. The project will integrate these testbeds with the ProtoGENI effort from the University of Utah, which is itself based upon that group’s Emulab software.

The primary contributions of this work towards GENI Spiral 1 are the integration of HOMENET, CMU wireless emulator, and CMULab into the ProtoGENI control framework (includes federation & Internet2 connectivity); extension of HOMENET capabilities to support node/experiment management & isolation; definition/refinement of control framework elements such as RSpecs; and expansion of HOMENET user opt-in control.

Spiral 1 Connectivity


The CMU Lab internal cluster and Wireless Emulator are NATted behind The Lab will connect to the nearest ProtoGENI node on Internet2 via GRE tunnel (unless an economical VLAN strategy can be found). CMU access the Internet via 3ROX operated by PSC using a link with over 500 Mbps spare capacity. 3ROX is not on I2's DCN.

HomeNet nodes will tunnel (IP-in-IP) to CMU Control using OpenVPN. The nodes will have addresses assigned by the user's ISP and may be assigned private addresses by HomeNet.


802.11q tagged VLANS will be used establish QoS-enabled Ethernet VLANs between the CMU emulab cluster and the CMU wireless emulator. ProtoGENI will provide dynamic VLAN establishment between Utah emulab clusters and CMU Lab.
