Welcome to Join Framework#

Join is a modular C++ network runtime framework for Linux, designed for low-latency, high-throughput, and system-level networking.

It provides a set of composable libraries covering networking primitives, concurrency, serialization, cryptography, and Linux network fabric management.

🎯 Design Goals#

  • Linux-native networking (sockets, netlink, raw sockets)
  • Event-driven and reactor-based architecture
  • Strong separation of concerns via modular libraries
  • High test coverage and correctness-first design
  • Suitable for infrastructure, control-plane, and runtime components

🚀 Why Join?#

Join focuses on providing robust, efficient building blocks for:

  • Network runtimes
  • System services
  • Control planes
  • High-performance servers
  • Infrastructure tooling

📦 Modular Architecture#

The framework is a collection of specialized modules that build upon one another:
