eNSP Topology Skill

Generate eNSP (Enterprise Network Simulation Platform) topology files as native .topo files that can be opened directly in eNSP.

How to create a topology

1. 1. Parse user's request to identify:

- Network devices (routers, switches, PCs, Cloud, etc.) - Connections between devices - Optional: text labels, area boxes

1. 2. Generate UUIDs for each device using a valid UUID v4 format

1. 3. Calculate layout coordinates for devices using auto-layout algorithm

1. 4. Build the .topo XML following the format in INLINECODE1

1. 5. Write the file to current directory using Write tool

1. 6. Open the result - print the file path so user can open it in eNSP

Output format

Always output a .topo file. The user will open it in eNSP for simulation.

Example filenames:

• - INLINECODE3
• INLINECODE4
• INLINECODE5

Layout algorithm

Use a simple grid-based auto-layout:

CODEBLOCK0

Adjust positions based on device types and connections to create logical groupings.

Adding text labels (txttips)

Common labels for network diagrams:

• - Loopback addresses: INLINECODE6
• Network segments: INLINECODE7
• Area labels: Area0, Area1, INLINECODE10
• Device roles: Core Layer, INLINECODE12

Adding area boxes (shapes)

Use type="1" shapes with appropriate colors to group devices:

• - Same area devices in one rectangle
• Different colors for different areas/zones

File naming

• - Use lowercase with hyphens
• Descriptive name based on topology purpose
• End with .topo extension

Opening the result

After writing the file, print the absolute path:
CODEBLOCK1

XML format reference

Consult references/topo-reference.md for complete XML structure including:

• - Device XML format with slots and interfaces
• Line XML format with interfacePair details
• Shape XML format for area boxes
• Txttip XML format for text annotations
