This project is a cross-platform C library designed for implementing MQTT messaging in applications. It serves as an asynchronous networking toolkit that enables resource-constrained systems and distributed components to exchange telemetry data and control signals with messaging brokers. The library distinguishes itself through a state-machine-based protocol handler that manages connection lifecycles and persistent session states, ensuring reliable message delivery even during intermittent network connectivity. It utilizes a background thread to manage network operations, allowing application
NATS Server is a high-performance, lightweight messaging system designed for cloud-native applications, edge computing, and distributed microservices. It functions as a distributed publish-subscribe broker that routes messages using hierarchical, dot-separated subject strings, enabling decoupled communication between services without requiring centralized broker lookups. The system supports core messaging patterns including asynchronous publish-subscribe, request-reply, and load-balanced queue processing. The platform distinguishes itself through a decentralized architecture that eliminates t
This project provides a technical specification and reference manual for the MQTT 3.1.1 standard, serving as a translated Chinese guide for implementing this lightweight IoT messaging protocol in resource-constrained device networks. The documentation covers the fundamental mechanisms of the publish-subscribe model, including topic-based routing with wildcard filtering, retained message storage, and the configuration of last will and testament messages. It details the protocol's approach to reliability through various quality of service levels, ranging from single-level acknowledgments to exa
This project is a Java messaging software development kit designed to facilitate real-time data exchange between applications and message brokers. It functions as an MQTT client library, providing the necessary tools to implement publish-and-subscribe messaging patterns within distributed systems and internet-connected device environments. The library distinguishes itself through its focus on resilient network connectivity and reliable message delivery. It manages persistent connections through internal state machines that handle automatic reconnection and keep-alive heartbeats, ensuring stab
