The project addresses the GENI challenge of architectural experimentations across diverse heterogeneous technologies by supporting real-time cross-layer communications and measurements. Our objective is to develop networking capabilities within the GENI infrastructure that enable deeper exposure of cross-layer information and user access to real-time measurements.[[BR]] == Project Summary == By the end of year 1, we evaluated GENI's capabilities for embedded real-time measurements and cross-layer control. Further, we proposed the development of a Unified Measurement Framework (UMF), and joined Cluster D to integrate UMF into ORCA-BEN. [[BR]] By the end of year 2, we designed and implemented a NetFPGA-based UMF. We demonstrated an experimental use-case that was run locally at Columbia University. Moreover, we integrated UMF with the Integrated Measurement Framework (IMF) and collaborated on an experimental use-case run on the Breakable Experimental Network (BEN) located in North Carolina. Finally, we began plan to expand UMF into other infrastructures within GENI. [[BR]] ERM is currently in its third year. The spiral 3 goals are: - Developing a more universally deployable UMF implementation, which we call the ‘ERM Box’. [[BR]] - Expand the deployment of this box into multiple GENI infrastructures. [[BR]] - Conduct an experiment using the ERM-enabled network involving non-GENI researchers. [[BR]] - The experimental work will be complemented by the development of network models and a simulation environment released to the GENI community to further ERM-enabled networking research. [[BR]] - Contribute to the GENI I&M architecture effort.

We identify a set of specifications for the implementation of a unified, integrated measurement framework with the ultimate purpose of limiting the hardware and software overhead and complexity associated with accessing measurement data.[[BR]] ''[http://groups.geni.net/geni/attachment/wiki/Embedded%20Real-Time%20Measurements/GENI_MS3_ERM_March09_v1-0.pdf Technical Note Milestone 3]'' To enable and perform discrete-event network simulations and quantitatively evaluate performance impact under several scenarios of cross-layer information exchange based on real-time measurements we developed new simulation modules for the ns-2 open source network modeling environment and make them available to the GENI community at: ''[http://lightwave.ee.columbia.edu/?s=research&p=ns2 ERM software module repository]'' ''(Columbia University New York, Alcatel-Lucent Bell Labs)'' [[BR]] ''[http://groups.geni.net/geni/attachment/wiki/Embedded%20Real-Time%20Measurements/GENI_MS4_ERM_June09_v1-0.pdf Technical Note Milestone 4]'' This milestone deals with the development of a measurement framework based on GENI real-time measurement requirements and other developments/resources within the GENI prototyping activities. Interacting with other prototype efforts, we identify and leverage relevant activities, software architectures, protocols, and products. This work deals with a number of software architectures dedicated to network measurements which could serve as an interface between a unified measurement framework (UMF), the control framework, and the GENI experimenter. We assess several network management protocols and data exchange formats with respect to their ability of exchanging measurement and control information between the substrate's performance monitors and the UMF, as well as between the UMF and the GENI control frameworks. [[BR]] ''[http://groups.geni.net/geni/attachment/wiki/Embedded%20Real-Time%20Measurements/GENI_MS5_ERM_Sept09_v1-0.pdf Technical Note Milestone 5]'' The release of this milestone document was postponed until after the proceedings of the European Conference on Optical Communication were published (end of September 2009). Support GPO in developing an experimental use-case (completed 09/01/2009) The goal of this milestone was to support the GPO in developing experimental designs for use-cases based on our work on a measurement-driven cross-layer communication system. Building on the successful simulation work with the previously developed modules, we validate our cross-layer communication schemes in developing an experimental use-case based on proactive packet protection. We show network simulations, as well as an experimental demonstration, of our packet protection scheme. [[BR]] ''[http://groups.geni.net/geni/attachment/wiki/Embedded%20Real-Time%20Measurements/GENI_MS6_ERM_Sept09_v1-0.pdf Technical Note Milestone 6]'' We have evaluated various control frameworks to assess the feasibility of joining a GENI cluster and integrating our work on real-time measurements within one of these clusters. In this milestone, we discuss this endeavor and our recent decision to join the Cluster D ORCA team.
