About This Architecture
Modular protocol stack architecture organizes communication layers into four tiers: Core Protocol (codec and transport), Client/Server Libraries, Helper Libraries, and Programs with loadable extensions. Data flows upward from TCP/UDP transport through encoder/decoder components to reusable helper libraries that support both server and client programs. This layered design enables teams to build extensible, maintainable protocol implementations where extensions (.so modules) can be loaded into the server without recompiling core logic. Fork this diagram on Diagrams.so to customize helper libraries, add new transport protocols, or document your own modular stack architecture.
