Features

• Reactor Pattern Event Loops - Utilizes an event-loop-based reactor pattern to handle high-concurrency network I/O and connection events.
• Event-Driven I/O - Utilizes a system-level event loop to asynchronously monitor network I/O and trigger callbacks for millions of concurrent connections.
• Asynchronous Networking - Employs an asynchronous networking architecture that decouples data transmission from business logic.
• Binary Protocols - Supports custom binary protocol design using codecs for efficient data framing and serialization.
• Event-Driven Networking - Implements an event-driven networking engine using non-blocking I/O to handle massive concurrency.
• High-Concurrency Networking - Designed for high-concurrency networking capable of managing millions of simultaneous connections.
• HTTP Request Routing - Maps incoming HTTP URL paths to specific handler functions to generate and send responses to web clients.
• Message Encoders and Decoders - Implements customizable encoders and decoders to convert raw byte streams into structured network messages.
• TCP Server Frameworks - Provides a high-performance C++11 framework for building concurrent TCP and UDP servers.
• Asynchronous I/O Libraries - Functions as an asynchronous I/O library providing a non-blocking interface for system network operations.
• SSL/TLS Connection Security - Integrates security libraries to provide an SSL/TLS wrapper for encrypted asynchronous data transmission.
• Half-Sync Half-Async Patterns - Implements a half-sync/half-async processing model to decouple network I/O from business logic.
• OS-Specific Event Notifications - Leverages low-level OS notifications like epoll and kqueue to scale to millions of concurrent connections.
• Timed Event Scheduling - Schedules and manages tasks to execute at specific intervals or after delays using internal timers.
• Time Wheel Schedulers - Implements a timer-wheel scheduler for managing delayed or recurring tasks with constant-time complexity.
• Codec-Based Message Framing - Uses codecs to automatically frame incoming data into structured messages and send them over a connection.
• C++ HTTP Server Libraries - Implements C++ HTTP server functionality including route matching and request handling.
• Incoming Message Processors - Handles incoming data as raw reads or decoded messages using customizable codecs to simplify protocol parsing.
• Persistent Connection Enablements - Maintains open connections to remote servers using configurable timeouts to reduce latency.
• TCP Transport Connections - Creates managed TCP transport connections to specified hosts and ports using smart pointers for memory management.
• Connection Configuration Interceptors - Allows intercepting the connection acceptance process to configure specific settings or state for new client connections.
• UDP Communication - Provides tools to send and receive data using the User Datagram Protocol for fast, connectionless transmission.
• Idle Connection Pruning - Automatically terminates inactive network sockets based on timer thresholds to reclaim system resources.
• Secure Network Communication - Integrates encryption libraries to provide secure, encrypted data transmission through secure sockets.
• SSL-Enabled Socket Wrappers - Provides SSL-enabled socket wrappers to encrypt TCP, UDP, and HTTP data transfers.
• Thread-Safe Dispatchers - Provides thread-safe dispatching to route tasks from worker threads back to the IO thread.
• Connection Context Storage - Implements mechanisms for associating persistent state and metadata with specific network connections for retrieval during event callbacks.
• HTTP Servers - Provides a core HTTP server engine for routing web traffic and managing request-response cycles.
