  1. perfSONAR WG Meeting(06FMM) Jeff W. BooteMartin Swany Internet2 6 Dec 2006

  2. Overview • motivations/overview • NMWG Schema Overview (Martin Swany) • Discovery (Martin Swany) • AuthN/Z • Current Status • Open Discussion

  3. Vision: Performance Information is … • Available • People can find it (Discovery) • “Community of trust” allows access across administrative domain boundaries (AA) • Ubiquitous • Widely deployed (Paths of interest covered) • Reliable (Consistently configured correctly) • Valuable • Actionable (Analysis suggests course of action) • Automatable (Applications act on data)

  4. Getting There: Build & Empower the Community Decouple the Problem Space: • Analysis and Visualization • Performance Data Sharing • Performance Data Generation Grow the Footprint: • Clean APIs and protocols between each layer • Widespread deployment of measurement infrastructure • Widespread deployment of common performance measurement tools

  5. Result: No more mystery … • Increase network awareness • Set user expectations accurately • Reduce diagnostic costs • Performance problems noticed early • Performance problems addressed efficiently • Network engineers can see & act outside their turf • Transform application design • Incorporate network intuition into application behavior

  6. perfSONAR Overview • What: Measurement infrastructure for exchanging data under development • How: Webservices network performance framework • Network measurement tools • Network measurement archives • Distributed scheduling/authorization • Multi-domain policy • Common language (GGF NMWG Schema) • Where: Deployed / to be deployed across: • Network Backbones (Abilene, ESNet, GÉANT) • Regional Networks (NRENs, RONs, Gigapops) • Universities • When: First product release happened summer ‘06

  7. perfSONAR: What is it? • Service Oriented Architecture (discovery, AuthN/Z, federation…) • Base schema (NMWG) to allow any performance data type with a defined extensibility

  8. perfSONAR: Services (1) • Lookup Service • Allows the client to discover the existing services and other LS services. • Dynamic: services registration themselves to the LS and mention their capabilities, they can also leave or be removed if a service gets down. • AuthN/Z Service • Internet2 MAT, GN2-JRA5 (eduGAIN) • Authorization functionality for the framework • Users can have several roles, the authorisation is done based on the user role. • Trust relationships defined between users affiliated with different administrative domains.

  9. perfSONAR Services (2) • Transformation Service • Transform the data (aggregation, concatenation, correlation, translation, etc). • Topology Service • Make the network topology information available to the framework. • Find the closest MP, provide topology information for visualisation tools • Resource protector • Arbitrate the consumption of limited resources between multiple services.

  11. Overview • motivations/overview • NMWG Schema Overview (Martin Swany) • Discovery (Martin Swany) • AuthN/Z • Current Status • Open Discussion

  12. perfSONAR: Core Team Status Update • First production release of Java Sample Implementation (July 06) • Includes: • Single domain LS solution • RRD MA • Other closely integrated implementations/applications: • BWCTL MP • perfSONAR UI

  13. perfSONAR: authN/Z plans • perfSONAR(JRA-1)/JRA-5 sub-group • Group tasked with determining how to leverage JRA-5 authentication system (eduGAIN) in perfSONAR infrastructure • Jeff Boote (Internet2) • Diego Lopez (RedIRIS) • Maurizio Molina (Dante) • Andreas Solberg (Uninett)

  14. AuthN/AuthZ Background • Designed with Federated authentication in mind • AS becomes a ‘proxy’ for Authorization requests

  15. eduGAIN: Background • JRA-5 provided authentication “interface” • Provides “bridging” to other authentication systems • Shibboleth • PAPI • Others… • Designed mostly with web-browser interaction in mind

  16. Current Auth Status • Group has come to general consensus on how this should work

  17. perfSONAR: Trust relationship entities • Client • idP (identity provider) • pSR (perfSONAR resource “service”) • AS (perfSONAR AS service) • HLS (Home Location Service)

  18. Automated Client Interaction

  19. Normal User Interaction

  20. Overview • motivations/overview • NMWG Schema Overview (Martin Swany) • Discovery (Martin Swany) • AuthN/Z • Current Status • Open Discussion
