  1. ESnet Network Measurements Joe Metzger Presented at ESCC Feb 5 2008

  2. Outline • ESnet • Goals • Provide Services to ESnet Users • Encourage community deployment • Roadmap • Deployment Activities • Research & Development Activities • ESnet Sites • Participation • Deployment • Next Steps

  3. Providing Services to ESnet Users • Support adhoc network measurements for troubleshooting and infrastructure verification. • By ESnet Staff within the backbone • By ESnet sites to the backbone • By ESnet customers across the backbone • Support regularly scheduled tests for diagnosing problems, demonstrating capabilities and monitoring. • Between ESnet POPS • Between ESnet sites & peers to ESnet POPs • From sites across ESnet. • Visualization • Allow ESnet user community to better understand our network & it's capabilities. • Allow ESnet users to understand how their use impacts the backbone. • Alarming • Automated analysis of regularly scheduled measurements to raise alerts.

  4. Foster Community Deployment • Developing recommendations on how to use and deploy the tools: • http://fasterdata.es.net • Hardware • Software • Measurements • Which scheduled & adhoc measurements should be setup • How to interpret results • Working with focused communities • LHC Tier 1 & 2 • Universities • Others

  5. Deployment Activities(1) • Deployed the Hardware in the ESnet backbone • OWAMP Servers (>5 left) • BWCTL Servers (>5 left) • Deployed tools to support adhoc measurements for debugging • OWAMPD • BWCTLD • Harden the infrastructure • Centralized management of OS & Services configuration • Continuous monitoring of servers & services • Performance tuning & verifying everything is working as designed.

  6. Deployment Activities(2) • perfSONAR Buoy Deployment • Between ESnet systems • To Internet2 & GEANT • To/From ESnet Sites • Topology Service • Utilization Service • Simple GUIs for all of the above

  8. Research & Development Activities • Scaling & robustness enhancements • Visualization Tools • Single Domain Tools • Utilization Browser • Topology Browser • Latency & Bandwidth Browser • Advanced Tools • Looking across multiple domains • Looking at correlations between different types of measurements • Application or user community specific views • Alarming • Integrating OSCARS circuits • Topology • Utilization • Active measurements across them

  9. Outline • ESnet • Goals • Provide Services to ESnet Users • Encourage community deployment • Roadmap • Deployment Activities • Research & Development Activities • ESnet Sites • Participation • Deployment • Next Steps

  10. ESnet Site Planning • Identify Measurements • SNMP • Utilization • Errors • Active • Latency • Bandwidth • Topology • Identify Users • Who will use the data and how? • Evaluate publication issues • Is the data already published? • Are there security concerns? • Can they be addressed?

  11. ESnet Site Deployment • Hardware • Generic White boxes • Koi System • Software • Site policy will influence your options • NPToolkit • RPMs • Source distributions

  12. Next Steps • Using the Measurement Infrastructure • http://fasterdata.es.net • Lists of deployed services • Brief instructions on how to use them • Pointers to lots of other resources. • Should we start a more organized ESCC community deployment effort? • ESnet Site mailing list? • Working group?
