<section title="Introduction">
<t>This draft describes extensions to the SCTP sockets API (see <xref target="RFC6458" />, <xref target="RFC4960" />) which allow an application to configure the behaviour of the Concurrent Multipath Transfer (CMT) extensions CMT-SCTP, CMT/RPv1-SCTP, CMT/RPv2-SCTP and MPTCP-like (see <xref target="I-D.tuexen-tsvwg-sctp-multipath" />, <xref target="Globecom2010" />, <xref target="PAMS2012" />, <xref target="Dre2012" />, <xref target="PAMS2011" />, <xref target="SoftCOM2011" />, <xref target="ConTEL2011" />, <xref target="AINA2010" />, <xref target="IAS2006" />).</t>

<section title="Concurrent Multipath Transfer and Resource Pooling Activation/Deactivation (SCTP_CMT_ON_OFF)">

<t>This socket option activates or deactivates CMT and sets the corresponding Resource Pooling variant to be applied. The sctp_assoc_value structure is used to specify the association for which the CMT state should be changed and the new CMT state.</t>

<t>Definition of the sctp_assoc_value structure:
<figure>
<artwork>
struct sctp_assoc_value {
   sctp_assoc_t assoc_id;
   uint32_t     assoc_value;
};
</artwork>
</figure>

<list style='hanging'>
 <t hangText="assoc_id:">Holds the identifier for the association of which the CMT state should be changed. Ignored for one-to-one style sockets.</t>
 <t hangText="assoc_value:">
  <list style='hanging'>
   <t hangText="0">Turns CMT off.</t>
   <t hangText="1">Turns plain CMT-SCTP on. No Resource Pooling is applied.</t>
   <t hangText="2">Turns CMT-SCTP on. CMT/RPv1 Resource Pooling as defined in <xref target="AINA2010" /> is applied.</t>
   <t hangText="3">Turns CMT-SCTP on. CMT/RPv2 Resource Pooling as defined in <xref target="ConTEL2011" /> is applied.</t>
   <t hangText="4">Turns CMT-SCTP on. MPTCP-like Resource Pooling as defined in <xref target="SoftCOM2011" />, <xref target="ConTEL2011" />, <xref target="PAMS2012" /> is applied.</t>
  </list></t>
</list>
