Network Simulation Python Packages

virl2-client

Client library for the Cisco VIRL 2 Network Simulation Platform

network-sandbox-engine

A deterministic network sandbox for testing nftables rules. It uses ephemeral Linux network namespaces (netns) and Scapy to validate firewall logic safely.

isaac-net

GPU-batched 5G network simulation for massively parallel robot learning: thousands of Isaac Lab / MJX environments, network-in-the-loop on one GPU, validated against ns-3 5G-LENA and OAI

nethang

This is a web-based tool for simulating network quality. Ideal for use with software routers on Linux platform. It focuses on simulating weak network (poor network) conditions, with built-in scenario models(3G, 4G, Wi-Fi, Starlink, etc.) and combinations of parameters such as packet loss, delay, jitter, and bandwidth limitation, etc.

p4net

Mininet-style P4 SDN sandbox in Python. BMv2 + P4Runtime native, Linux netns / veth / tc, topology DSL, interactive CLI.

ntn-constellation

End-to-end ns-3.43 simulator for 6G non-terrestrial networks: measured NR-NTN data plane under SGP4 mobility, NTN/O-RAN application layer with in-band QoS KPIs, E2SM-KPM flow monitor, multi-tier RIC, regenerative payloads, TR 38.821-calibrated radio, all 5 NTN handover trigger classes, THz, Sionna RT, AI/ML, digital twin.
