NSI Aggregator Implementation

• SURFnet BoD and OSCARS are uPA only
• Will depend solely on this Aggregator for inter-domain services
• NSI Aggregator
• can be deployed in different environments and functionality can be

tuned to these environments by build time selection of modules

• At this time, the different environments include ESnet,

NORDUnet+SURFnet+GEANT, the A-GOLE

• Has a simple administrator web GUI for monitoring and debugging
• Does *not* have a user web GUI, use the GUI of your network’s

What is it?

• Standalone path computation engine built for use by the

SURFnet/ESnet aggregator NSA.

• 100% Java server implemented using the lightweight Grizzly HTTP

container, Jersey 2.2 for JAX-RS, Spring for IoC, and Jung for graphing.

• Provides a REST-based path finding, NSI topology, and

management interfaces supporting both JSON and XML encodings.

• Supports both local file and GitHub-based HTTP discovery

mechanisms for NML topology.

• Utilizes configurable path finding modules allowing for different

algorithms and custom data handling to be incorporated.
