13		The NPE in the SPP provides an extensive collection of performance monitoring counters. These are maintained by the datapath software and are accessible to the xScale management processor. We have developed software to allow a remote user to monitor these counters and have the values displayed on remote real-time charts, allowing researchers to observe what is happening "under the covers'' as traffic flows through their fastpath running on the NPE. The software consists of three components. First, there is a user interface implemented as a java application that the user runs on a remote machine.
