- Purpose: to confirm network performance and plan new networks among the earth observation community.

- Changes: NASDA upgraded the ATM Line Between Tsukuba and the EOC on Oct 27th, 2001. 2M → 4M(bps)

- Tools: tcpwatch, ping, traceroute

There are wide margin between max. value and min. value due to heavy traffics a few times in a day. (as a result of MRTG between Tsukuba and EOC.)

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.)

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.

NASDA(hdds4c11@HEOC) -> NASA(g0aeg01@GSFC)

2001

EOIS


- 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 performance was 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?
