1. Advanced Networking Collaborations at SLAC
Presented by Warren Matthews at the ESCC Meeting, BNL, NY, June 2001

2. Overview Theme: Internet2 Collaboration Monitoring High Performance
PingER, Surveyor, RIPE, AMP, NIMI, IPEX
High Performance
QoS, Web100 and QBSS
IPv6
VoIP, International, E2E

3. SLAC and Internet2 SLAC’s primary internet connection is with ESnet
SLAC also has connection to Stanford
Route to CalREN/Abilene sites
Involved with several I2 Working Groups
Also experimental connection to NTON

4. PingER Ping End-to-end Reporting With HEPNRC/FNAL
And many local administrators (including I2)
32 Monitoring sites in 14 countries
Coming soon: Africa
434 Remote sites in 73 countries

5. Surveyor Advanced Network and Services Inc
Widely deployed in Internet2
One-way delay measurement
Synchronized by GPS
UDP packets

6. RIPE-TT Reseaux IP Europeens (RIPE) NOC Similar to Surveyor
UDP packets
SLAC involved in original deployment
Now production service
Working on statistical analysis with statistician from IBM.

7. AMP Active Monitoring Project NLANR Ping Monitoring
Many HPC award Sites (Internet2)
Several sites outside U.S.

8. NIMI National Internet Measurement Infrastructure
NIMI box at SLAC since 1998
Deploy Active Internet Measurement for ESnet (AIME)
Advanced Monitoring
Schedule tests
Detailed characterization of links

9. IPEX Cross Industry Working Team (XIWT)
Passive Monitoring Project developed by AT&T Research
Funded by DARPA
Hire a student if the lawyers can agree on the contract

10. High Performance NTON Large windows and multiple streams Caltech GSFC
2.4Gbps
Large windows and multiple streams
Achieved 100MBps
Caltech
BaBar Monte Carlo Production
GSFC
GLAST Data

11. QoS With Daresbury Lab in UK Internet2 Project
BaBar plans Tier-1 site at RAL
Congestion exists transatlantic US->UK
Implement CAR on Janet NY Router

12. Qbone Scavenger Service
Less than Best Effort
Trickle data to Tier-1 sites without impacting other services
Application or Router sets bits to mark packets
Currently ignored by network
Implemeted on dorm network at two Universities

13. Web100 Development by NCAR and PSC Optimize TCP parameters
Modifications to Linux Kernel
Alpha 0.2 released
Upcoming workshop
SLAC, LBL and ORNL evaluators

14. IPv6 SLAC, FNAL, ORNL, ESnet Internet2 IPv6 Working Group
Recent workshop
Most effort in the core
Deploy machines and services
Make data available

15. VoIP SLAC Deployed Voice-over-IP Inter-lab via ESnet Testbed
Nortel PBX, Cisco 3640
Inter-lab via ESnet Testbed
CERN, DESY via regular routing
I2 Working group formulating plan
Implement dialing plan

16. International HENP covers the whole world
ESnet International and Internet2 International Groups
Keep track of networks carrying HENP traffic.
Arena

17. End-to-end Initiative
IEPM not particularly E
Mostly WAN
Some LAN
I2 End-to-End Initiative
Les attended kick-off meeting

18. Summary
A lot of common ground between ESCC Community and Internet2 Universities
A lot of useful work
need to build on it
Need to implement findings better

19. Any Questions ?
