+= Basic Experiment with GEMINI v1.1 I&M Tools: Instructions =
+
+
+
+== Preparation ==
+
+This tutorial assumes that attendees have a basic knowledge of ProtoGENI/InstaGENI, and we recommend that interested participants also consider attending the InstaGENI tutorial offered at GEC 15.  [[BR]]
+
+Active participants will need a laptop equipped with a recent version of [http://www.virtualbox.org/ Virtual Box]. If you are unable to bring one, you may partner with someone else.
+
+== Steps ==
+
+
+=== 0)  Overview of experiment ===
+
+0.1)  Title and abstract
+
+0.2)  Goals
+
+0.3)  Configuration
+
+0.4   Process  (flow chart)
+
+
+=== 1)  Establish experiment environment ===
+
+1.1)  Establish experiment managment (user workspace) service
+
+1.2)  Gather necessary keys, certificates and credentials
+
+1.3)  Verify availability of desired aggregates
+
+1.4)  Verify availability of desired software images/packages
+
+1.5)  Verify availability of necessary operational services, and access to those services
+
+
+=== 2)  Obtain slice of GENI resources, install I&M tools and experiment services ===
+
+2.1)  Select target aggregates
+        
+2.2)  Select desired software images/packages for I&M tools and experiment services
+
+2.3)  Obtain certs, credentials, passwords and keys
+
+2.4)  Formulate slice topology for experiment, and build request rspec
+
+2.5)  Acquire resources and load images/packages for I&M tools and experiment services
+
+2.6)  Start selected software processes 
+
+2.7)  Confirm slice with installed I&M tools and experiment services
+
+
+=== 3) Configure I&M tools and experiment services ===
+
+3.1)   Configure selected I&M services
+
+ - objectives:
+   - binds services together, e.g., between each MP and the MC
+   - configures baseline services
+   - verifies that they are ready to run
+ 
+ - at completion:    configured I&M services, ready to run and collect data
+ 
+
+3.2)  Configure selected experiment services
+
+ - objectives:
+   - binds services together to realize overall reference/actual experiment
+   - configures baseline services
+   - verifies that they are ready to run   
+   
+ - at completion:    configured experiment services, ready to run and process data, which can be observed by I&M services
+ 
+  
+=== 4)  Run and orchestrate I&M services and experiment services to complete run of experiment ===
+
+
+4.1)  Initial setup:  start basic host measurements and basic ping active network measurements
+
+ - objectives:
+   - verify functionality of hosts 
+   - verify topology of slice
+
+ - observe measurements with a real-time presentation service
+ 
+ - continue measurements throughout duration of the test/tutorial/experiment
+ 
+ - at completion: 
+   - functionality of hosts and topology of slice has been verified throughout duration of the experiment
+ 
+ 
+4.2)  Continuity test:  for a limited time, run iperf active network measurements 
+
+ - objectives:
+   - verify ability of slice to carry traffic expected from experiment 
+
+ - observe measurements with a real-time presentation service
+ 
+ - once satisfactory measurements have been observed, stop continuity test 
+ 
+ - at completion: 
+   - capability of slice to carry traffic expected from experiment has been verified
+
+   
+4.3)  Instrument and run experiment:  
+
+ - objectives:
+   - gather measurements during experiment that allow experiment goals to be met
+   
+ - include desired measurement points within hosts and/or experiment services to instrument test/tutorial/experiment
+ 
+ - begin to run and orchestrate measurement services
+ 
+ - begin to run and orchestrate experiment services
+ 
+ - observe measurements with a real-time presentation service, to verify expected operation of experiment
+ 
+ - collect all measurements for duration of experiment
+ 
+ - stop experiment services, when this run of the experiment has been completed
+ 
+ - stop measurement services
+ 
+ - at completion:
+   - one run of experiment has been completed
+   - real-time look at measurements has verfied expected operation of experiment
+   - a full set of measurements has been collected, for later analysis and presentation
+   - collected measurments have been transfered to storage service, so that slice resources can be released (if desired) 
+   
+4.4)  Store collected measurements and other artifacts from test/tutorial/experiment in storage service 
+
+ - at completion:
+   - collected measurements and other artifacts have been transfered to storage service
+   - collected measurements and other artifacts are available for later analysis
+   - slice resources can then be released at any time, without loss of any measurements or artifacts
+   
+=== 5)  Analyze and visualize measurement results after completing run of experiment ===
+
+ - if necessary, retrieve measurement results from archive service
+ 
+ - analyze and format results as desired, for visualization with presentation service
+ 
+ - as appropriate, store analyzed results and/or visualization in storage service
+ 
+
+=== 6)  Move selected collected measurements and other artifacts from storage service to long-term archive service ===
+
+ - identify archived objects with peristent identifier
+ 
+ - include policy for sharing with others
+ 
+ - allow retrieval for further analysis and visualization
+
+
+=== 7)  Release experiment resources  ===
