Crate ndn_sim 

ndn-sim — In-process NDN network simulation

Provides SimFace, SimLink, and a Simulation topology builder for constructing multi-node NDN networks entirely in-process. Unlike Mini-NDN (which orchestrates real processes via Mininet), simulations run in a single Tokio runtime with configurable link properties.

Quick Start

use ndn_sim::{Simulation, LinkConfig, NodeId};
use ndn_engine::builder::EngineConfig;

let mut sim = Simulation::new();
let n1 = sim.add_node(EngineConfig::default());
let n2 = sim.add_node(EngineConfig::default());
sim.link(n1, n2, LinkConfig::lan());
sim.add_route(n1, "/prefix", n2);

let running = sim.start().await?;
// ... run experiment using running.engine(n1), running.engine(n2) ...
running.shutdown().await;
