How long will it take for a ping to be sent?

In the "24 Ping and Pong Messages" chapter of WebsocketAPI_ProtocolSpecification.pdf, It say that if a Refinitiv server doesn't receive traffic for a certain period of time, it will send a Ping message to the application.
Regarding this "certian period of time", how many seconds does it specifically refer to?

Thank you for reaching out to us.

There are two values related to a ping mechanism (ping interval and ping timeout).

Those values are configurable on the server. If you are connecting to the Real-Time Optimized, the ping interval is 20 seconds and ping timeout is 30 seconds. The server will send a ping message to the client every 20 seconds.

After sending a ping message, if the server didn't receive any messages from the client for 30 seconds, the server will cut the connection, as shown below.

Hi @Jirapongse .

Thank you for your answer.

Our understanding is that for Real-Time Optimized, pings will not be sent as long as there is traffic, regardless of the type, such as MarketPrice.
Is this understanding correct?

The ping mechanism is used to make sure that the another end is still active and alive.

The server will send a ping message after the client connects to the server.
