5 University of Kentucky January 31, 2011 Joint Techs 2011 GENI A national-scale suite of infrastructure for long-running, realistic experiments in Network Science and Engineering. Deeply programmable Virtualized Mobile Wireless Network Edge Site Sensor Network Federated International Infrastructure Programmable, federated, with end-to-end virtualized slices

6 University of Kentucky January 31, 2011 Joint Techs 2011 Source: ProtoGENI m ProtoGENI components m A nationwide high-speed backbone on Internet2’s wave infrastructure m Slicable PCs with NetFPGA cards embedded within the backbone m A set of subnets, including a variety of wireless networks, residential broadband, and programmable edge clusters

7 University of Kentucky Motivations for Monitoring GENI Networks o Much of the work on testbeds has focused on creating, setting up, and running an experiment o Create application-specific virtual networks o Time scale: minutes o The real challenge can often be monitoring and analyzing the behavior of an experiment; it can be a very involved, time consuming, manual process that is repeated many times. o It involves setting up and launching a monitoring environment. Joint Techs 2011 January 31, 2011

8 University of Kentucky Project Goals/Objectives m The ultimate objective is to q Automate the task of deploying an instrumentation and measurement infrastructure within a GENI slice. q Provide users with a convenient and simple-to-use interface to the measurement infrastructure. m Preliminary steps toward this objective q Implement an instrumentation and measurement tools to work in the ProtoGENI environment (INSTOOLS) Joint Techs 2011 January 31, 2011

9 University of Kentucky January 31, 2011 Joint Techs 2011 Monitoring Challenges o Multiple uses o Debug o Verify the configuration o Verify the experiment is behaving correctly o Learn/Discover o Understand what happens and why o Measure performance o Requires o deciding what information should be monitored about the network, OS, and applications o selecting the level of detail for monitoring o monitoring desired information o filtering information to be reported o collecting/transporting recorded data o making information available/viewable to users.

10 University of Kentucky January 31, 2011 Joint Techs 2011 Monitoring Challenges o Scaling to large experiments.  Monitoring load on components  Collect/transport instrumentation data  Without interfering with the experiment  Collecting data from many components o Logging for history view and archival purposes. o Security and authorization to access monitoring capabilities. o Sandboxing the monitoring system. o Accounting for monitoring activity.
