# Alive Message

To ensure that the connection between the client system and the Betradar system is working properly, alive messages (or so called connection test messages) get sent. The client should expect a message from the server at least every 8 seconds. In return, the client system should send the server a message ever 30 seconds.&#x20;

If either the client or the server has not received any messages within the given time frame the connection should be restarted.

**XML example**

```xml
<ct/>
```
