Lawrence Berkeley National LaboratoryU.S. Department of Energy | Office of Science 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 uRA 3

Lawrence Berkeley National LaboratoryU.S. Department of Energy | Office of Science NSI Path Computation Element v1.0 REST Interfaces Validation Validates request against known service templates Scheduler Discovery and auditing Remote task control through REST API Configuration Runtime configuration Logging Local HDD logging. Remote log access through REST API Topology Manager Consolidates interdomain topology and builds domain model. Path Computation Core Orchestrates path computation Returns resolved path request segments NSI PCE 5 NSAs (Topology) NSAs (Topology) Find Path API Topology API Management API Path Modules Configurable path computation modules Topology Providers Dynamic topology discovery NML to NSI topology conversion Client Path results Path request Management NSI topology

Lawrence Berkeley National LaboratoryU.S. Department of Energy | Office of Science 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. 6
