Rust-libP2P GossipSub Test Node

The rust-libp2p based test node provides a flexible and extensible environment for GossipSub experiments. It supports yamux/quic transports, and follows the same features and architecture as in the the nim-libp2p and go-libp2p test nodes.

Features

• Configurable test node parameters
• Multi-transport support (Yamux, QUIC)
• Message fragmentation support
• HTTP-based message injection for dynamic test configuration
• Latency measurements for message propagation
• Prometheus metrics collection
• Kubernetes and shadow deployment

Environment Variables

• PEERS — Number of peers in the network (default: 100)
• CONNECTTO — Target number of peers to dial (default: 10)
• MUXER — Stream multiplexer (default: yamux)
• FRAGMENTS — Number of message fragments (default: 1)
• SHADOWENV — Whether running in shadow simulator (default: false)
• SERVICE — K8s service name for peer discovery (default: nimp2p-service)
