+'''__Project Overview__'''
+The objective of our project is to develop, test and deploy a prototype implementation of the
+network instrumentation and measurement systems that will eventually be widely available in the
+GENI infrastructure. The specific components of the instrumentation and measurement system
+include sensor nodes that will gather packets from links in a network, a measurement data
+repository and the experimental interfaces that enable users to specify the data that will be
+gathered for their experiments. The major milestones in this project are, 1) to produce a
+specification describing the requirements and capabilities of the systems, 2) to build and test the
+measurement systems in the Wisconsin Advanced Internet Lab (WAIL), and 3) to deploy a
+limited number of measurement systems in NLR. The objectives for the project in year 1 are as
+follows:
+  a. Develop system interface design specification and distribute via appropriate GENI working groups. (4 mo. from start date)
+  b. Develop measurement system design specification and distribute via appropriate GENI working groups. (4 mo. from start date)
+  c. Develop repository system design specification and distribute via appropriate GENI working groups. (4 mo. from start date)
+  d. Develop basic instrumentation and measurement test suites for evaluating measurement implementations in WAIL. (6 mo. from start date)
+  e. Develop a prototype with basic measurement functionality, including interface to a GENI control framework (v 1.0). Test implementation in WAIL. (10-12 mo. from start date)
+  f. Make basic functionality prototype available to GENI users in WAIL testbed . (11-12 mo. from start date)
+
+'''__QSR !#1 Executive Summary__'''
+The project officially started in the final week of October when funds were received at UWMadison
+from the GPO. Prior to that date, the PIs had initiated weekly conference calls to start
+the process of specifying the requirements and capabilities of the GENI Instrumentation and
+Measurement systems (GIMs). Mike Blodgett at UW-Madison (WAIL lab manager) – who is
+the only person other than the PIs who is partially funded by our GENI grant – began the process
+of investigating the control framework interface and sensor components of GIMs. In particular,
+the initial version of GIMs will be developed as part of the ProtoGENI control framework. Since
+Mike has worked extensively with Emulab and the Utah developers, he already has a substantial
+working knowledge of the underpinnings of ProtoGENI. Mike has been in regular contact with
+the Utah ProtoGENI group about the integration of the GIMs capabilities. In terms of sensor
+components, Mike and PI-Barford have been investigating several possible alternatives including
+general-purpose PC-based systems and more specialized packet capture/inspection systems. Co-
+PIs Crovella and Sommers along with Mike Blodgett participated in the GENI Engineering
+Workshop at the end of October.

+=== A. Activities and findings ===
+The majority of the activities that have taken place since the official
+inception of this project (end of October, ‘08) have revolved around the planning and
+organization of the specification documents of the GENI measurement and instrumentation
+systems. This activity has been facilitated by weekly conference calls between the PIs. An
+initial draft of the GIMs Specification is underway and will be completed by early January, 2009.
+
+Investigations of possible hardware platforms for the sensor nodes that will be deployed on
+network links in GENI have begun. The two primary possibilities are general-purpose PC-based
+systems and more specialized measurement systems (e.g., Endace and Bivio). Considerations for
+the platform selection include performance, programmability, measurement accuracy, and timing
+accuracy and cost. Two students will begin work on developing the initial functional capabilities
+of the sensor nodes in the first quarter of 2009.
+
+Investigations of the ProtoGENI control framework (GIMs initial integration target) have also
+begun. Mike Blodgett’s extensive experience with Emulab and the Utah developers gives him a
+substantial working knowledge of the underpinnings of ProtoGENI. Unfortunately, since much
+of ProtoGENI exists only in the form of a specification, progress on specifying details of the
+ProtoGENI/GIMs interface has been limited.
+
+An important first step in ProtoGENI integration was to upgrade the WAIL testbed to the 5.X
+series of Emulab code. This clears the path to integrate our router-based testbed into the
+ProtoGENI ecosystem. Since WAIL’s extensions to Emulab include many site-specific changes,
+and the integration of some external systems, the upgrade process is complicated. The work to
+remove these local issues, either by replacing their functionality or contributing changes
+upstream is ongoing and should streamline future updates of our systems.
+
+Finally, Co-PIs Crovella and Sommers along with Mike Blodgett participated in the GENI
+Engineering Workshop at the end of October. A poster was generated and co-PI Sommers gave
+a talk on the GIMs project.
