+= Internet Scale Overlay Hosting Progress Report (12/2010-3/2011) =
+
+== 1. Project Activities this Quarter ==
+
+In this quarter, we added two more SPP nodes completing the 5 node
+deployment planned under this project. The additional nodes have been
+integrated into the testbed and applications using the full five
+node configuration were demonstrated at GEC-10.
+We have continued to provide operational support for the deployed SPPs
+and have worked with users to facilitate their use of the SPPs.
+
+=== SPP Applications ===
+
+We have worked with Brighten Godfrey of the University of Illinois
+to develop a new NPE fastpath for the SPPs. This implements the
+Illinois group's ''Slick Packets'' protocol, that allows dynamic
+re-routing around failed links, based on alternate path information
+encoded in the packet headers. Initial measurements show a substantial
+improvement over implementations running on a conventional processor,
+but a detailed performance evaluation is yet to be carried out.
+The new NPE fastpath was demonstrated at GEC-10.
+
+At GEC-10, we also carried out a larger scale demonstration
+of our Forest overlay network. This demonstration used a new end-system
+emulator that behaves like a simple avatar moving around within a virtual
+world, while transmitting periodic status updates on region-specific
+multicast groups. Each emulator dynamically subscribes to multicasts
+for regions that are visible to it and maintains state for the
+avatars that are within its visibility range. The demonstration also
+included a monitor component and a remote graphical display giving
+a "birds-eye" view of the avatars moving within the virtual world.
+The demonstration showed 100 avatars distributed among three distinct
+virtual worlds, each of which used its own comtree.
+It made use of the full five node SPP testbed and 25 planetlab nodes.
+
+=== Flow Monitoring ===
+
+The flow monitoring system is now complete, but our final testing on
+the deployed SPPs was interrupted when the Control Processor in the
+Salt Lake City SPP experienced a hardware failure.
+We are in the process of having the CP replaced and expect to
+have the Salt Lake City node back in service before the end of April.
+At that point, we will complete our testing and deploy the flow
+monitoring software on the remaining SPP nodes.
+
+=== Version 2 of Network Processor Datapath Software ===
+
+While the software for the NPE datapath is essentially complete,
+we still need to make changes to the control software to allow applications
+to configure and use the NPE with the new fastpath. This work is now
+in progress and our current objective is to demonstrate NPE v2 at
+GEC-11.
+
+=== SPP Tutorial ===
+
+We gave our fourth SPP tutorial at GEC-10. 
+More than 25 people signed up and 18 actually attended.
+All participants reported having a good experience and
+almost all of them successfully completed the hands-on exercises.
+
+=== GEC-10 Preparation and Attendance ===
+
+Preparation for and attendance at GEC-10 consumed about one
+staff-month of effort. This continues to consume a major part
+of our  supported activity.
+
+== 2. Milestones achieved ==
+

+
+== 7. Collaborations ==
+
+Completed implementation of NPE fastpath implementing the
+Slick Packets protocol developed by Brighten Godfrey of 
+the University of Illinois.
+
+Have made extensive use of PlanetLab in experimental network
+configuration in which SPPs serve as backbone nodes.
+
+Have established connections between SPP nodes and the GPENI and MAX
+networks, but have not yet made significant use of these resources.
+
+Have been using Plush/Gush tools for configuring SPP nodes.
+
+Have demonstrated experiments that use combination of SPP and PlanetLab nodes.
+
+Have had initial discussions with Jim Griffoen of the University of Kentucky,
+about using SPPs in support of his Post-Modern Internet Architecture.
