Concerns Test Routes A and B - On Apr 13th EOC-GSFC route,average throughput dropped by 75%. (Figure 3) However in TKSC-GSFC route, no changes come out(Figure 4). (Traceroutes before and after Apr 13th are shown in Figures 5 and 6.) - On Jun 14th average throughput rose by 100% . (Figure 3) - Same phenomenon are appeared in other nodes.
Figure 3 6/14 up 4/13 down
Concerns (continued) Test Route C - After July 16th in the HEOC- ASF route, average throughput fell by almost 12%. (Figure 7) Almost same phenomenon are appeared in other node. NASDA didn’t make any changes to the network configuration.

Proposed Investigations • Test Routes A and B(Internetroute) • In HEOC–TKSC–GSFC route, As it shown in Figure 3 on HEOC-GSFC • route, the throughput suddenly down on Apr 13th. • However the throughput does not change in TKSC-GSFC route. • NASDA replaced FireWall on Apr 13th at EOC. • We are investigating influence of replacement or another factor. • Test Route C (EBnet route ) • As it shown figure 7 ,There is a dropping in average throughput on Jul 16th . • From the results of traceroute,(figue 8a,b) there are some delay after • 202.251.177.186 . What makes it so ? • NASDA didn’t make any changes to the network configuration. • Should they be investigated ?
Other News • NASDA will switch US route to APAN instead of SInet . -NASDA Will Change to JAXA on Oct. 1st. Domains will change following. $$$.nasda.go.jp $$$.jaxa.jp Also the old domains will be able to use until end of Sep. 2004.
