Paragon Planner Overview

Juniper’s Paragon Automation suite of applications includes Paragon Planner, which helps network operators to effectively plan and design their network.

Paragon Planner is a network modeling tool that enables offline visualization of network resources and provides detailed architectural planning of the production networks. Paragon Planner allows you to simulate network changes and other traffic scenarios without affecting the live network. Paragon Planner helps you forecast the effect of network changes and assess the network for potential failure scenarios.


Support for Paragon Planner web application is a Beta feature in the Paragon Automation Release 21.3.

Key Features and Use Cases

Key features and use cases of Paragon Planner include:

  • Automatically construct network topologies by using data snapshots of live networks (obtained from Paragon Pathfinder) or source data from stored network configuration files and other sources.

  • Perform capacity planning to determine whether there is sufficient capacity or if more capacity should be added, and which links can be pruned without compromising resiliency.

  • Analyze traffic loads to determine accurate link utilization for failure simulation.

  • Validate network changes (in a safe, virtual environment) before deployment.

  • Run what-if scenarios to anticipate the impact of any network change.

  • Create and model VPNs, simulate VPN routing, and generate VPN traffic.

  • Simulate multicast flows based on user-defined multicast groups and demands.

  • Design and simulate MPLS traffic engineering (MPLS-TE) and label-switched path (LSP) routing.

  • Assess network resiliency against different failure scenarios and analyze how traffic is rerouted and its effect on network links.

  • Ensure service-level agreement (SLA) compliance by a modeling class of service (CoS) classes and policies and queuing schemes. (You can define application flows based on CoS to enable the modeling of voice over IP (VoIP) or video on demand (VOD) traffic.)

  • Model and analyze BGP routing.

  • Hardware inventory.

  • Network integrity checks.

Benefits of Paragon Planner

  • Lower CapEx and OpEx (hardware and maintenance costs) by using Paragon Planner's tariff-based design, MPLS LSP, and segment routing traffic engineering (SR-TE) features for effective utilization of the network, and superior design optimization.

  • Quickly diagnose performance problems by using flow analysis, congestion detection and analysis, peak utilization analysis, and multicast simulation features.

  • Optimize plans for future network growth (to meet business needs) by using capacity planning and data forecasting.

  • Avoid problems and mitigate risk by assessing the network using Planner’s resiliency analysis, fiber cut analysis, and so on.

  • Validate new services, equipment, and technologies before they are rolled out.
