SERIAL NETWORK FLOW MONITOR (SNFM)
Research Area: Avionics and Software
Expedition(s): 9-ongoing
Principal Investigator(s): ● Carl Konkel, The Boeing Company, Houston, Texas
RESEARCH OBJECTIVES
Serial Network Flow Monitor (SNFM), using a commercial software CD, monitors the payload
local area network (LAN) to analyze and troubleshoot LAN data traffic. Validating LAN traffic
models allows for faster and more reliable computer networks to sustain systems and science
on future space missions.
EARTH BENEFITS
Locating and correcting computer
network problems alleviates data
downlinking issues, which allows
scientists on the ground to receive
data from their experiments.
SPACE BENEFITS
SNFM extends International Space
Station (ISS) accommodations to sub-
rack payloads, provides a set of
standard interfaces and resources for
sub-rack payloads, supports the
simultaneous and independent
operations of multiple payloads
within the rack, and accommodates
multiple science disciplines. This
information will allow monitoring
and improvement in the data
transfer capabilities of in-orbit
computer networks.
RESULTS
Data analysis is ongoing.
This investigation is ongoing and additional results are pending publication.
