Network Digital Twin

The Network Digital Twin is the analytical model that ENP uses to simulate behavior, compare scenarios, and study risk.

Read this section when you already have a basic understanding of the interface and a design loaded in ENP.

What This Section Is For

Use the Network Digital Twin pages when you need to answer questions such as:

  • How will routing behave under current policies?
  • What happens if demand grows?
  • What happens if a link, node, or shared risk group fails?
  • How do optical or transport constraints affect the result?
  • Which services or paths are impacted by a given change?

Simulation Inputs From Existing Controllers

In deployments where the relevant module is enabled, ENP can build or refresh part of the Digital Twin from existing SDN controllers and similar external sources.

This matters because routing, resilience, traffic, and multi-layer studies can be executed on top of the imported model once the controller data is present in the design.

For the integration model, supported interfaces, and module requirement in Network Planner, see SDN controller integration.

Main Simulation Areas

IP/MPLS Simulation

These pages explain the main IP-layer analytical models:

Optical and Transport Simulation

These pages cover optical and transport-specific modeling:

Failure and Resilience Analysis

Use Failure simulation and analysis to understand Shared Risk Groups (SRGs), what-if failure studies, and vulnerability analysis.

Suggested Reading Order

If you are new to simulations in ENP, this is a good order:

  1. IGP simulation
  2. BGP simulation
  3. Failure simulation and analysis
  4. Traffic monitoring and forecast
  5. Optical and transport pages only if they apply to your environment

Before Reading The Detailed Pages

The detailed pages in this section are reference-oriented and can be dense. If you still need orientation, go back to:
