Server Ready frame – spec §5.5.

The Ready frame is the final handshake frame. It is sent by the server after the session is fully established (and any resume exchange is complete). It carries the runtime parameters the client needs to operate correctly on this connection.

After receiving Ready the client may begin publishing and subscribing to topics.

Fields

session_id: String

Unique session identifier assigned by the server.

epoch: u32

Monotonically increasing epoch counter for this session.

ping_interval_ms: u32

Minimum interval in milliseconds between consecutive Ping frames the client must send.

pong_timeout_ms: u32

Maximum time in milliseconds the client should wait for a Pong reply before considering the Ping missed.

max_missed_pongs: u32

Number of consecutive missed Pongs that triggers connection teardown on the client side.

idle_timeout_ms: u32

Idle timeout in milliseconds; the connection will be closed if no frames are received within this window.

jitter_ms: u32

Maximum random jitter in milliseconds to add to the effective ping interval, used to prevent heartbeat synchronization across many clients.

max_payload_bytes: u32

Maximum payload size in bytes for a single frame on this connection.

max_topics_per_connection: u32

Maximum number of topics this connection may subscribe to simultaneously.

max_send_queue_bytes: u32

Maximum size in bytes of the client’s outbound send queue before the server will apply back-pressure or close the connection.

server_time: i64

Server wall-clock time in milliseconds since the Unix epoch at the moment the Ready frame was generated.
