NeST: A Python based Network Emulator for Education and Research
summary
NeST claims it turns Linux network namespaces into a reproducible emulator via a Python wrapper around Linux network namespaces, building virtual topologies, setting latency/bandwidth and running real kernel TCP stacks (tested against NS-3 with comparable accuracy). It creates folders with PCAP and JSON outputs and auto-generated plots, supports RIP, OSPF, IS-IS and MPLS, adds MQTT and tshark integration, scales to ~30+ nodes limited by host resources, and runs reliably on single machines or servers.
