+/**
+ * @defgroup reliable Reliability Layer module
+ *
+ * The Reliability Layer is part of OpenVPN's control channel. It
+ * provides a reliable and sequential transport mechanism for control
+ * channel messages between OpenVPN peers. This module forms the
+ * interface between the \link external_multiplexer External
+ * Multiplexer\endlink and the \link control_tls Control Channel TLS
+ * module\endlink.
+ *
+ * @par UDP or TCP as VPN tunnel transport
+ *
+ * This is especially important when OpenVPN is configured to communicate
+ * over UDP, because UDP does not offer a reliable and sequential
+ * transport. OpenVPN endpoints can also communicate over TCP which does
+ * provide a reliable and sequential transport. In both cases, using UDP
+ * or TCP as an external transport, the internal Reliability Layer is
+ * active.
