Fiber Network Ring Optimization Using GIS | Hierarchical Parent–Child Ring Design

Smart, GIS-driven fiber ring design for reliable and scalable connectivity.

This project builds an optimized fiber network model using GIS to create structured parent and child rings for reliable connectivity. It analyzes roads, BHQs, and GPs through shortest-path routing, maps critical infrastructure like tunnels and bridges, and integrates everything into a custom QGIS plugin for fast, accurate network planning.

Building Smarter Fiber Networks

We developed an optimized road and fiber-based network model to ensure structured connectivity across multiple regions.
Using geospatial datasets, the model integrates parent, logical, and child ring formations for efficient communication paths.
Each GP is connected to its respective BHQ through shortest-path routes, minimizing redundancy.
This ensures reliability, scalability, and optimal utilization of existing infrastructure for rural and urban communication planning.

Mapping Critical Infrastructure

Identifying tunnels and bridges within the road network enhances both design safety and implementation accuracy.
By classifying critical infrastructure elements, planners can anticipate challenges and optimize network routes accordingly.
This capability supports better decision-making during fiber or road installation and maintenance.
The result is a more reliable, field-ready network that accounts for real-world structural constraints.

Optimizing Network Design

Parent and child rings are intelligently analyzed to determine optimal connectivity between BHQs and GPs.
Through shortest-path algorithms like Dijkstra’s, the tool minimizes total fiber length while maintaining network redundancy.
It integrates new connections with existing OFC corridors, ensuring both cost-effectiveness and reliability.
This structured hierarchical model enhances planning, accessibility, and long-term scalability of rural and urban networks.

Seamless QGIS Integration

The entire automation workflow has been developed as a custom QGIS plugin, enabling easy operation for planners and GIS professionals.
Users can select road, GP, and BHQ shapefiles, run the analysis, and instantly visualize the optimized rings and tunnel/bridge outputs.
The tool streamlines geospatial network analysis and eliminates manual data handling errors.
This seamless integration accelerates project execution and ensures consistent, high-quality outputs.

Hierarchical Rings, Smarter Reach

Model parent and child fiber rings in a single geospatial view for truly hierarchical connectivity.
The engine links primary BHQ backbones with secondary distribution loops, keeping every cluster of GPs online.
Child rings automatically attach to the nearest parent ring, balancing redundancy with build cost.
See exactly where coverage is strong, where gaps remain, and how each new ring improves resilience.
