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.

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.

-Test Routes A and B （ Internet route) 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 ?
Proposed Investigations
EOIS
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.
