1. Measurements on Internet2
Matt Zekauskas
IBM Internet2 Day
26 July 2001

2. Overview Our Philosophy: Openness
What’s available? Also collaborators…
Measurement projects using Internet2
Measurements of the Abilene backbone
End to End Performance
We will be looking for collaborators soon
Internet2 coordinates, members do work
Internet2 Measurements - 26 Jul 2001

3. Measurement Goals Support Operations Network Engineering
Performance, Utilization: status & debug
Network Engineering
Trends, Characterization
Network Research
Characterization, Performance, Utilization
Feedback to applications?
Internet2 Measurements - 26 Jul 2001

4. Measurement Projects Surveyor (one-way delay, loss, routing)
On many Internet2 campuses (70 sites)
Abilene presence
AMP (round-trip delay, loss, routing)
moat.nlanr.net/AMP : UCSD, Waikato (NZ)
At even more Internet2 campuses (120 sites)
PMA (passive, packet traces)
moat.nlanr.net/PMA : UCSD, Waikato (NZ)
1 min, 8 times a day, ~13 sites
Internet2 Measurements - 26 Jul 2001

5. Measurement Projects PingER (round-trip delay, routing) NIMI
Long term data from a few locations to many
High-energy physics focus : SLAC, DoE, XIWT
NIMI
: PSC, Wisc
Designed to be platform for experiments
Undergoing some redesign/revitalization
~ 60 sites?
Internet2 Measurements - 26 Jul 2001

6. Host Focus Measurement Project
Web100
: PSC + NCAR + NCSA
Instrument TCP stack
Tunable (auto-tunable?) host parameters
Remove host / OS as bottleneck (for network activity… disk? app?)
Internet2 Measurements - 26 Jul 2001

7. Others Pioneer Mantra http://pelle.internet2.edu:8080/pioneer/
Synthesis of existing infrastructure
Focus: video conferencing tests
“application-level” example
Mantra
Multicast network health
Internet2 Measurements - 26 Jul 2001

8. Universities PSC/CMU: NCNI+NIMI+Web100 / TCP
UCSD: NLANR Passive, and Active
U Waikato: Passive monitoring technology, lead on AMP
Wisconsin: unify infrastructures, passive + active + web tests (Barford)
Tennessee: Network Weather Service
PI moving to UCSD (Wolski)
Indiana: Abilene, and discovering layer2
…and many others

9. Abilene Abilene goal to be an exemplar Measurements open
Tests possible to router nodes
Web-mediated on-demand measurements
Throughput tests routinely through backbone
…as well as existing utilization, etc.
Internet2 Measurements - 26 Jul 2001

10. Passive - Utilization The Abilene NOC takes Packets in,out
Bytes in,out
Drops/Errors
..for all interfaces, publishes internal links & peering points (at 5 min intervals)
..via SNMP polling – every 3 sec

12. Internet2 Measurements - 26 Jul 2001

13. Passive – Characterization
gigaPOPs & Universities doing own
Some sparse via NLANR/MOAT
Starting some NetFlow measurements
QoS
AS-AS information for K-12 & ITN
Intend to do some characterization
Internet2 Measurements - 26 Jul 2001

14. Packet Trace Project NLANR MOAT/Waikato (New Zealand)
Goal: New backbone traces
Looking to deploy some OC48 monitors
Desire to fully instrument one router
NOT near term, but perhaps in 6 months…
Internet2 Measurements - 26 Jul 2001

15. Others via Abilene NOC BGP Peering
MSDP (multicast source discovery) logging
See: -> Operational Status
Internet2 Measurements - 26 Jul 2001

16. E2Epi: JPL/Caltech – GSFC
The situation
Using Abilene
Tuned hosts
Things work locally
Therefore it MUST be Abilene
Tests show good flows router-router
Intermediate tests point towards CA
Bad fiber connection!
Internet2 Measurements - 26 Jul 2001

17. Summary Lots going on Data available
from measurement projects
from Abilene
Thus see network state for experiments using infrastructure
See also Measurement Working Group
So far, operational focus; research support in charter
