2. Project Goals Enable end-users & network operators to:
determine E2E performance capabilities
locate E2E problems
contact the right person to get an E2E problem resolved.
Enable remote initiation of partial path performance tests
Make partial path performance data publicly available
Be interoperable with other performance measurement frameworks
Encompass needs of next generation infrastructures

3. Decouple 3 components of a Measurement Infrastructure

4. Strategy Our strategy has been to focus effort in the middle tier
We are well leveraged to help build the measurement community needed to make this work (ESnet and Geant as well)
Allows a common interface for measurement tools to be built
Allows a common interface for analysis tools to be built
Enables researchers who are better positioned to do the “sexy” analysis or tool development to concentrate efforts on those portions of the problem

5. PerfSONAR Overview
Joint effort of ESnet, GÉANT2 JRA1 and Internet2 (and more)
Webservices network performance framework
Network measurement tools
Network measurement archives
Distributed scheduling/authorization
Multi-domain policy
Control communication via SOAP messages containing GGF NMWG schema

6. Services (Data) Measurement Archive Measurement Point
Storage of passive/active measurement results
Measurement Point
Request collection for passive
Request execution for active
Interacts with MA for storage
Transformation Service
Transform the data (aggregation, concatenation, correlation, translation, etc)
Example: ongoing analysis of data stream for NOC alarm, etc…

7. Services (Discovery) Lookup Service
Allows the client to find existing services and other LS services.
Dynamic: services can register/de-register/timeout
LS within a “domain” will have detailed knowledge of services within the domain
Inter-domain LS accomplished by sharing aggregated/summary information about what kinds of services are available along with a reference to the LS that hold detailed knowledge
Topology Service
Make the network topology information available to the framework.
Find the closest MP, provide topology information for visualisation tools
Algorithmic entity: Data is still held by Measurement Archives

8. Services (AuthN/Z) Resource protector Authentication Service
Internet2 MAT, GN2-JRA5
Authentication functionality for the framework
Users can have several roles, the authorization is done based on the user role
Basically, this is the interface between perfSONAR applications and services and “real” federated authentication systems
Resource protector
Arbitrate the consumption of limited resources.
Centralize the policy as much/little as wanted

9. Inter-domain perfSONAR example interaction

17. Conclusions
Many tools are becoming interoperable using the common GGF schema language (and specifically the perfSONAR dialect).
Good working relationships with the principles across multiple continents (Brazil is even becoming involved!)
The pace of development is increasing.
Real tools (i.e. analysis tools building on the minimal framework) are already in development now.
