    7981''[http://groups.geni.net/geni/attachment/wiki/Embedded%20Real-Time%20Measurements/GENI_MS1_ERM_March09_v1-1.pdf Technical Note Milestone 1]''  The capabilities of GENI's (future) infrastructure with respect to real-time measurements are evaluated and we assess the GENI requirements for real-time user access to measurement data across a diverse set of technologies.[[BR]]
    8082''[http://groups.geni.net/geni/attachment/wiki/Embedded%20Real-Time%20Measurements/GENI_MS2_ERM_March09_v1-0.pdf Technical Note Milestone 2]''  A set of specifications for enabling real-time measurements within the substrate and specifications for networking protocols based on the GENI requirements for real-time user-accessed cross-layer measurements is developed. 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]]
     
    8486''[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]]
    8587''[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) 
    86 The goal of this milestone was to support the GPO in developing experimental designs for usecases
    87 based on our work on a measurement-driven cross-layer communication system. Building
    88 on the successful simulation work with the modules developed in [erm09_1], we validate our
    89 cross-layer communication schemes in developing an experimental use-case based on proactive
    90 packet protection. We show network simulations, as well as an experimental demonstration, of
    91 our packet protection scheme. Additional information, as well as a technical note, on milestone 5
    92 is available online [erm09_1], [erm09_2].  [[BR]]

    9389''[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.  [[BR]]

     93''[http://groups.geni.net/geni/attachment/wiki/Embedded%20Real-Time%20Measurements/ERM_S2a_Dec09.pdf Technical Note Milestone S2.a]''  We outline a prototype implementation of the UMF using a NetFPGA Cube. The UMF uses both software (processor) and hardware (NetFPGA card) components in order to access the measurement data from embedded networking equipment.  [[BR]]
