+= GENI Desktop Project Status Report =
+
+Period: Post GEC 21 Report
+
+== I. Major accomplishments ==
+
+The following highlights our accomplishments during the last reporting period.
+
+=== A. Milestones achieved ===
+
+ * Modified the GENI Desktop to support "Speaks-for" authentication being developed/supported by the control frameworks and other GENI tools/services.  
+
+ * Incorporated user-driven feedback into the GENI Desktop to support user-requested services and features.  
+
+ * Developed new training materials that incorporate the changes made to the GENI Desktop. 
+
+ * Demonstrated "Speaks-for" and super slice support capabilities at GEC21.
+
+=== B. Deliverables made ===
+
+ * We enhanced the GENI Desktop to use "Speaks-for" credentials for accessing resources from other GENI components on behalf of users.
+
+ * We improved the user interface based on feedback from last GEC.
+
+ * We implemented an initial version of the slice verification and configuration testing service.
+
+ * We developed code for super slice support in the GENI Desktop. 
+
+== II. Description of work performed during last quarter ==
+
+The following provides a description of the progress made during the last reporting period.
+
+=== A. Activities and findings ===
+
+Our activities this last reporting period have been primarily focused on
+developing code for supporting "Speaks-for" authentication, implementing 
+an initial version of the slice verification and configuration testing service, and
+desinging "super slice" functionality. We also made various enhancements 
+to the GENI Desktop's user interface based on feedback from users. 
+
+The "Speaks-for" credential allows trusted tools to act for, instead of 
+acting as, an experimenter to perform certain actions, such as requesting 
+resources from aggregates, accessing allocated resources, and installing 
+software on experimental nodes. We enhanced the GENI Desktop to use "Speaks-for" 
+credentials for accessing resources on behalf of users. Users no longer 
+need to provide the private key to the GENI Desktop. We implemented an interface
+for the user to authorize the GENI Desktop to speak for her/him.  A GENI
+Desktop-specific certificate is signed using the private key of the user. 
+Because the whole process happens within the browser on the client side,
+the private key never leaves the user's machine. The "Speaks-for" credential 
+allows the GENI Desktop to talk to aggregates and perform all necessary 
+actions on behalf of the user. 
+
+We implemented the slice verification and configuration testing service
+as a module in GENI Desktop by taking advantage of the module builder function 
+of the GENI Desktop. Based on the manifest of an experiment, the verification
+service analyzes the topology and performs tests about the interfaces of all 
+nodes in the experiment. The initial version we implemented checks whether 
+each interface is up and whether it is reachable from a ping test. 
+The states are presented in a table showing the status of all the interfaces of 
+all the nodes in the experiment. 
+
+Building a large experiment is a difficult task in GENI, partly because 
+it is more likely to fail if we create an experiment with a lot of nodes.
+At the same time, we may have multiple related experiments and want to 
+combine these relatively small experiments together to form a large experiment.
+We developed a new "super slice" service in the GENI Desktop to support this functionality.
+Users can use the GENI Desktop to create a super slice by combining multiple 
+existing slices together. The GENI Desktop provides a GUI for users to display
+multiple slices at the same time and pick any pair of nodes from different 
+slices to establish a link between them. The Super Slice service in the GENI
+Desktop currently can then automatically set up GRE tunnels between these selected pairs of nodes 
+from different slices. 
+
+[[Image(geni_desktop_gec21_demo.png, 600)]]
+
+Finally, we demonstrated these new features of the GENI Desktop at GEC 21.
+The figure above shows three different slices are displayed and a pair of 
+nodes are selected. The super slice function will create a GRE tunnel
+between these pair of nodes.
