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)

Jeff W. Boote: 4 Dec 06

Getting There: Build & Empower the Community

Decouple the Problem Space:•Analysis and Visualization•Performance Data Sharing•Performance Data GenerationGrow the Footprint:•Clean APIs and protocols between each layer•Widespread deployment of measurement infrastructure•Widespread deployment of common performance measurement tools

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

Jeff W. Boote: 4 Dec 06

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

Jeff W. Boote: 4 Dec 06

perfSONAR: What is it?

• Service Oriented Architecture (discovery, AuthN/Z, federation…)• Base schema (NMWG) to allow any performance data type with a

defined extensibility

Jeff W. Boote: 4 Dec 06

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.

Jeff W. Boote: 4 Dec 06

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.

Jeff W. Boote: 4 Dec 06

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

Jeff W. Boote: 4 Dec 06

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)

Jeff W. Boote: 4 Dec 06

AuthN/AuthZ Background

• Designed with Federated authentication in mind

• AS becomes a ‘proxy’ for Authorization requests

Jeff W. Boote: 4 Dec 06

eduGAIN: Background

•JRA-5 provided authentication “interface”•Provides “bridging” to other authentication systems

•Shibboleth•PAPI•Others…

•Designed mostly with web-browser interaction in mind

Jeff W. Boote: 4 Dec 06

Current Auth Status

• Group has come to general consensus on how this should work

Jeff W. Boote: 4 Dec 06

perfSONAR: Trust relationship entities

•Client•idP (identity provider)•pSR (perfSONAR resource “service”)•AS (perfSONAR AS service)•HLS (Home Location Service)
