+== 1. Project Activities this Reporting Period ==
+
+=== Lightweight Flow Setup Application ===
+During this period, we extended the IPv4 application that runs on the
+SPPs to support a fast reservation option. This allows end hosts to
+reserve bandwidth on an end-to-end path, using an embedded IP option.
+Enabled routers select alternate routes, as appropriate, in order to
+satisfy the reservation, and make a partial reservation when they
+are unable to find a path that accommodates the full request.
+This work was done primarily to provide users with an example application
+that uses software running on one of the general purpose server blades to
+dynamically control a fastpath running on the embedded Network Processor.
+This application was demonstrated at GEC-9 and will be incorporated into
+future tutorials and documented in the SPP wiki.
+
+=== Initial Work on New Fastpath Application ===
+We have been working with Brighten Godfrey of the University of Illinois to
+develop a new fastpath code option that supports alternate routing in the presence of
+link failures, using a compact encoding of alternate paths carried in packet
+headers. We expect to complete work on this application and demonstrate it
+at GEC-10.
+
+=== Operational Support ===
+
+The SPPs have now transitioned out of development mode into a largely
+operational mode. We are working to provide effective and consistent support
+for users, while continuing to make improvements to the systems.
+
+=== Improving System Stability ===
+
+We have diagnosed and fixed a memory leak in the Linecard software for the SPP that led
+the system to crash periodically. The systems are now much more stable and
+have been operating reliably for months.
+
+=== GEC-9 Tutorial ===
+
+About 20 people attended the SPP tutorial at GEC-9. The session went very
+smoothly with users generally managing to complete the hands-on activities
+successfully.

+== 7. Collaborations ==
+
+Have established connections between SPP nodes and the GPENI and MAX networks, but still need to fully test the connections and verify the performance matches expectations.
+
+Have begun 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.
+
+Working with Brighton Godfrey of University of Illinois on pathlet routing experiments.
