Period of inactivity before sending a keep-alive packet. Keep-alive packets prevent an inactive but otherwise healthy connection from timing out. Only one side of any given connection needs keep-alive enabled for the connection to be preserved.

Maximum duration of inactivity to accept before timing out the connection. The true idle timeout is the minimum of this and the peer’s own max idle timeout.
