@mikkelfj The way Picoquic does it is through these API:
```
/* Enables keep alive for a connection.
 * If `interval` is `0`, it is set to `idle_timeout / 2`.
 */
void picoquic_enable_keep_alive(picoquic_cnx_t* cnx, uint64_t interval);
/* Disables keep alive for a connection. */
void picoquic_disable_keep_alive(picoquic_cnx_t* cnx);
```
If the API is enabled, the transport will in fact send PING frames, but only if there is not enough application traffic or other traffic to sustain the connection.
