-<t>When the streamed content changes the new Configuration is sent in-band before the actual stream, and the Configuration that has to be sent inline in the SDP updated. Since the inline method is unreliable, an out of band fallback is provided. The client could choose to fetch the Configuration from the alternate source as soon it discovers a Configuration packet got lost inline or use <xref target="RFC3611">selective retransmission</xref>, if the server supports that feature.</t>
