Jeff W. Boote

perfSONAR: Project Activity Meter

• 1-2 conf calls/week• 1 new service/month (accelerating)• 3-4 development workshops/year• 3-4 paper submissions/year

Jeff W. Boote

perfSONAR: System Description

•Domains represented by a set of services•Each domain can deploy services important to the domain•Analysis clients interact with service across multiple domains

Jeff W. Boote

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

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

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

perfSONAR: Background

• Designed with Federated authentication in mind

• AS becomes a ‘proxy’ for Authorization requests

Jeff W. Boote

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

Current Status

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

• Paper is currently underway describing interaction of perfSONAR with eduGAIN API

Jeff W. Boote

perfSONAR: Trust relationship entities

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

Jeff W. Boote

Automated Client Interaction

Jeff W. Boote

Normal User Interaction

Jeff W. Boote

Implications for JRA-5

• Future extensibility for multiple X.509 root CA certificates

• Non-web profile for authN attribute request

• Current identity provider servers (attribute stores) may need to hold attributes for non-human clients

• Others???

Jeff W. Boote

Implications for JRA-1

•AS has slightly different role•Clients never directly interact with AS•AS is effectively a ‘proxy’ between services and the eduGAIN

‘bridging elements’

•Attribute requests from services to RP’s and from RP’s to AS need to be made in a ‘boolean’ fashion to protect the privacy of clients•Automated clients MUST have X.509 client certificates
