HP-Socket is a networking library for building scalable TCP, UDP, and HTTP servers and clients with event-driven I/O and SSL encryption. It provides a high-performance TCP server framework, an HTTP request handler that parses incoming requests and generates responses, and a UDP communication library for low-latency data transfer, all with optional SSL encryption for secure communication.
The library is built on a completion-port-based I/O architecture that uses Windows I/O Completion Ports for scalable asynchronous socket operations. It features a connection-pooled agent architecture for managing multiple outbound connections, an event-driven callback model for handling connection, data, and shutdown events, and a multi-threaded worker pool for parallel processing. Object-pool memory management reduces allocation overhead, while a protocol-agnostic socket abstraction provides a unified interface across TCP, UDP, and HTTP. An SSL/TLS integration layer wraps socket streams with pluggable encryption for authenticated data transfer.
The library covers concurrent outbound connection management, TCP connection management for both servers and clients, and UDP data transfer for real-time communication needs. It also includes SSL-encrypted data transfer for secure communication across all supported protocols.
