NIST Integrated Services Protocol Instrument (ISPI)

ISPI is an interactive, integrated tool for measuring the performance of quality of service (QoS) sensitive data streams while conducting experiments with emerging Internet resource reservation protocols and real-time network services.  ISPI is capable of supporting stream selection based upon session directory protocols (i.e., SD, SDR), monitoring the performance of data streams that use the Real Time Transport Protocol (RTP) and allowing proxy interaction with routers supporting the Resource Reservation Protocol (RSVP).    In multicast applications, ISPI can be used to monitor the performance of all senders and receivers participating in a distributed, real-time application.    Interactive stream selection and filtering capabilities allows the ISPI user view cumulative statistics for all participants in a multiparty session, or to select and focus on specific sender/receiver pairs for more detailed performance data.
