BGP Route
Simulator

Simulate valley-free BGP routing entirely in-browser. Upload a topology, announcements, and ROV ASNs — get the full routing table for every AS in one click.

Input Files

Step 1

Graph Topology CAIDA relationship file (.txt)

Click or drag to upload graph topology

Announcements CSV seed_asn,prefix,rov_invalid

Click or drag to upload anns.csv

ROV ASNs CSV one ASN per line

Click or drag to upload rov_asns.csv

Filter by ASN (optional — leave blank to show every AS)

Simulation Results

Upload graph, anns, and ROV files, then click Run Simulation.

1 Upload graph topology (.txt)

2 Upload anns.csv and rov_asns.csv

3 Click Run — full routing table for every AS appears here

ASN	Prefix	AS Path	Length

How It Works

Upload Graph

Provide the CAIDA AS relationship graph file used to build the topology for this run.

Upload Inputs

Upload anns.csv and rov_asns.csv so the simulator can apply announcement seeding and ROV filtering.

Simulate

WASM runs valley-free propagation across the entire graph in a single call — no target ASN needed.
