Campus & Discipline Outreach  Internet2 Days  Talks and demos at discipline conferences  Working jointly with NLANR dast.nlanr.net

I2 Middleware Initiative: The “Services Rich” Network Environment

Or “From Circuits to Services”

What’s an Ideal “Internet2”  Functional services available to users and developers Enabling new collaborations and applications Supported as production quality An integrated framework  Scaled to the size of the research and education community

The Core  Identifiers for people, objects, groups  Authentication for people, objects and groups  Directories to store common information  Applications that use all of the above

I2 Middleware Activities  Early Harvest “Techshop”  Early Adopters

Measurements in Internet2 Matt Zekauskas SC99 Portland, OR November, 1999

‘My application has a problem’  Where is it? Network? Host (stack,config)? Application?  Local passive measurements can help localize the problem  Consistent measurement throughout Internet2 infrastructure can help diagnose network problems (and also help localize the problem)

Other Measurement Goals  Network engineering  Network research  Feedback to applications  Operational data performance, flows, anomalies  Network characterization how used? load response? SLS?

Today  All: at least SNMP statistics  Backbones: (vBNS, Abilene) publishing  Various uncoordinated activity

Today  Active measurement efforts: AMP (NLANR/MOAT), Surveyor (Advanced), {PingER}  Passive measurement effort: NAI (OCXmon) (NLANR/MOAT)

Delay Between Two East-Coast Tele-Immersion Sites

Working Group Activities  Measurement architecture  Encourage common Measurements, tools Parameters Reporting  Work with (at least) network management, QoS, multicast working groups

Ideal  Consistent measurement of Utilization Performance Traffic Characterization  With generally available results  Combined with “well known” measurement targets/observatories for on-demand tests

Also  Want some way to know where loss occurs when it happens (or delay)  Advanced service debugging Multicast QoS (QBone designing measurement in), additional E-E service verification?

Reporting  All measurements available via Web  Site/Router-relative URLs allows computed URL  I2-Wide measurements page to allow for browsing  Need to be cognizant of security & privacy issues mainly passive measurements

On the Horizon: TAAD  Traffic Analysis and Auto Diagnosis Developed by Matt Mathis and Kathy Benninger at NLANR ES Works on data collected by OCXmon (passive) Automatically diagnose specific types of TCP/IP performance problems Network limited flows Mis-tuned application or TCP stack When complete, available at:

Summary  Consistent measurement of Utilization Performance Traffic Characterization  That are made generally available  Plus targets/observatories  In support of applications and the networks themselves 
