nsi-orchestrator

The NSI orchestrator, based on the Workflow Orchestrator framework, maintains the lifecycle of network topologies, switching services, Service Termination Points (STP), Service Demarcation Points (SDP), and the Multi Domain Point-to-Point (MDP2P) services across a NSI infrastructure, using the NSI DDS Proxy as source of information and the NSI Aggregator Proxy as its Network Resource Manager (NRM).

Project ANA-GRAM

This software is being developed by the Advanced North-Atlantic Consortium, a cooperation between National Education and Research Networks (NRENs) and research partners to provide network connectivity for research and education across the North-Atlantic, as part of the ANA-GRAM project.

The goal of the ANA-GRAM project is to federate the ANA trans-Atlantic links through Network Service Interface (NSI)-based automation. This will enable the automated provisioning of L2 circuits spanning different domains between research parties on other sides of the Atlantic. The ANA-GRAM project is spearheaded by the ANA Platform & Requirements Working Group, under guidance of the ANA Engineering and ANA Planning Groups.
