Muduo is a C++11 event-driven network library and framework designed for building high-concurrency Linux servers. It provides a toolkit for implementing scalable network services and socket communication using non-blocking I/O and asynchronous event processing.
The framework implements a multi-threaded TCP server architecture that distributes connection handling across multiple CPU threads to maximize server throughput. This is achieved through a one-loop-per-thread model and a reactor pattern implementation, which dispatch network events from a central demultiplexer to registered handler functions.
The library covers core network programming capabilities including non-blocking I/O multiplexing via epoll and TCP connection abstractions that decouple network transport from application logic. It also provides a thread-safe event queue to manage tasks across different event loops.
