Juniper Paragon Pathfinder

Paragon Pathfinder (formerly NorthStar Controller) is a cloud-native controller that simplifies traffic engineering, making it easier for you to leverage benefits provided by transport service paths, such as MPLS/RSVP, segment routing, and network slicing. It enables your operations team to more efficiently manage strict transport service SLAs through automated planning, provisioning, proactive monitoring, and optimization of large traffic loads dynamically, based on user-defined constraints. With this automation, operators can run their networks “hotter” while achieving predictability, resiliency, and service-level guarantees in service provider, cloud provider, and large enterprise networks. Paragon Pathfinder provides you with granular visibility into network traffic flows and optimizes network capacity through closed-loop automation. It monitors your network in real time, gathering streaming telemetry, topology data from Netflow, IGP and BGP-LS from the network, and analyzing the data to provision new service paths based on user-defined SLA constraints.

Key Features


  • Manage, monitor, and provision segment routing and IP/MPLS paths in real time.
  • Offers intelligent interface between RSVP-TE networks and segment routing-enabled networks.
  • View live network topology maps that show node status, link utilization, segment routing paths, and label-switched paths (LSPs).
  • Automate the discovery of nodes, links, and paths from the network.
  • Create or schedule maintenance events to re-route traffic when issues arise.
