A JSON-RPC 2.0 based custom protocol providing remote procedure calls, publish-subscribe messaging, transactional operations, QoS, and message acknowledgment.
A JSON-RPC 2.0 based custom protocol providing remote procedure calls, publish-subscribe messaging, transactional operations, QoS, and message acknowledgment.
A versatile messaging protocol built on JSON-RPC 2.0 that adds structured communication patterns to WebSocket connections.
The SGC protocol uses JSON-RPC 2.0 as its message format, providing a standardized way to make remote procedure calls and exchange structured data over WebSocket connections. It supports multiple communication patterns including request-response RPC, publish-subscribe, and broadcast messaging. Built-in QoS levels and message acknowledgment ensure reliable delivery for critical applications.
Use the SGC protocol for publish-subscribe messaging.
