Performance Monitoring (1)

- Testing Internet Networks-

- 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.

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.

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 g0acg01, gsfcsafs, ASF

are rather long. Should they be investigated?
