2 CEOSnet CEOSnet is a virtual network organization; –Utilizes existing government and academic networks. Intended to support CEOS/WGISS related network activities. Network performance monitoring was a critical component of CEOSnet.

4 CEOSnet Monitoring CEOSnet monitoring gives indications of application-level performance. Network performance is tested between CEOSnet hosts throughout the world on various networks. –Performance is impacted by: Delay (round-trip times, distance); Congestion (packet loss); CEOSNet host configuration. Monitoring is done by the NASA Ensight system; –Andy Germain, GSFC / Swales Aerospace.

5 Ensight The NASA Ensight system was developed by EOS to passively and actively monitor and record historical network performance; Ensight (for CEOS) available at: ceos/index.shtml

10 Testing Matrix Testing can be configured between CEOSnet test hosts. Currently a full-matrix is not configured. Please contact myself or Mr. Andy Germain to add hosts or test matrices.
