24.1 Ping and Pong Message Descriptions
Ping and Pong messages are exchanged between endpoints of a connection to verify that the remote endpoint is still alive.
The Ping message may be sent by either endpoint. When either endpoint receives a Ping message, it should send a Pong message in response.
The Refinitiv Real-Time Advanced Distribution Server will send Ping messages to applications when it does not receive traffic for a period of time, so applications must be prepared to respond with a Pong message whenever they receive a Ping. Applications may likewise send Ping messages to elicit Pong messages from the Refinitiv Real-Time Advanced Distribution Server, but are not required to do so.
The Refinitiv Real-Time Advanced Distribution Server includes an informational PingTimeout element in its Login response, indicating the time (in seconds) after which the Refinitiv Real-Time Advanced Distribution Server will disconnect the application if it receives no traffic in response to a sent Ping.
