mrniko/netty-socketio

Features

• WebSocket Servers - Implements a server-side framework for managing persistent, bidirectional communication channels using the Socket.IO protocol.
• Real-time Communication Servers - Provides a high-performance server for handling live messaging and interactive bidirectional data streams.
• Distributed Socket Server Scaling - Scales real-time socket connections across multiple server instances using coordinated broadcasting via a message queue.
• Bidirectional Socket Communication - Implements bidirectional data streams between clients and servers using WebSockets and polling transports.
• Message Brokers - Acts as a distributed message broker to synchronize client state and broadcast events across multiple server nodes.
• Network Programming Frameworks - Leverages the Netty framework for high-performance, non-blocking I/O and scalable socket management.
• Room-Based Client Grouping - Organizes connected clients into namespaces and rooms to enable targeted event broadcasting and group messaging.
• Socket.IO Server Implementations - Provides a full Java-based implementation of the Socket.IO server for real-time bidirectional communication.
• WebSocket Transports - Implements a full-duplex WebSocket transport layer for high-performance, real-time data exchange.
• Distributed State Synchronization - Synchronizes session and runtime state across distributed server instances using an external data store.
• External State Connectors - Links the server to external data stores like Redis to synchronize client state and broadcasts across distributed nodes.
• Non-Blocking Event Loops - Utilizes a non-blocking event loop architecture to handle thousands of concurrent connections with minimal threading.
• Infrastructure Components - Provides the underlying infrastructure for organizing users into namespaces and rooms for targeted group messaging.
• Room-Based Message Routing - Organizes connected clients into virtual rooms to enable targeted broadcasting to specific subsets of users.
• Namespace Connectivity - Partitions communication into isolated logical namespaces to organize event handling and message broadcasting.
• WebSocket and HTTP Fallback Transports - Transparently switches between WebSocket and HTTP long-polling to maintain persistent session identity when WebSockets are unavailable.
• Event Routing Engines - Implements a real-time event engine for managing namespaces and rooms to send targeted events to specific user groups.
• WebSocket Security - Protects real-time data transfers using encryption and security certificates to secure stateful WebSocket connections.
• Event-Driven Messaging Systems - Implements an event-driven architecture that triggers specific server actions based on real-time events sent by clients.
