  10. Concerns Test Routes A (from EOC to each agencies) - After upgrading the ATM Line between Tsukuba and the EOC the average throughput improved and the maximums and minimums were more stable. [TKSC - GSFC(g0aeg01u), Figure 3] Test Routes B (from Tsukuba to GSFC) - After Oct 28th on the TKSC – GSFC(198.10.49.61) route, both average throughput and hourly throughput fell by almost 20%. (Figure 4) (Traceroutes before and after Oct 28th are shown in Figures 5.) CEOS Subgroup Meetings May 7-10, 2002. Frascati.

GSFC(gscsafs) 1653 - 937 8/07/01 - 3/02/02 3. ASF 1604 - 991 9/23/01 - 3/02/02 - Median Hourly Throughput - Destination Throughput ( Kbps) Period (mm/dd/yy) max. - min. 1.

  18. Concerns (continued) • Test Route C • As it is shown in Figure 7, Max average throughput continues to • be around 1700 Kbps. • The transmission buffer size was increased, but the • throughput didn’t improve. CEOS Subgroup Meetings May 7-10, 2002. Frascati.

  20. Proposed Investigations - Internet The performance decrease on the APAN - Abilene route should be investigated. - EBnet We performed an FTP performance test over EBnet between EOC and JPL(137.78.31.81) . The Average performancewas around 2.0 Mbps and Max performance was 2.35 Mbps. The results of the FTP test and traceroutes in Figures 8 to 11 indicate there is not a problem between 202.251.177.12 and 202.251.177.186. The traceroute times between 202.251.177.186 and g0aeg01, gsfcsafs, ASF are rather long. Should they be investigated? CEOS Subgroup Meetings May 7-10, 2002. Frascati.
