<section title="Introduction">
<t>This draft describes extensions to the SCTP sockets API (see <xref target="I-D.ietf-tsvwg-sctpsocket" />, <xref target="RFC4960" />) which allow an application to configure the behaviour of the Concurrent Multipath Transfer (CMT) extensions CMT-SCTP and CMT/RP-SCTP (see <xref target="I-D.tuexen-tsvwg-sctp-multipath" />, <xref target="Globecom2010" />, <xref target="AINA2010" />, <xref target="IAS2006" />).</t>

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

<t>This socket option activates or deactivates CMT. 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 CMT on.</t>
  </list></t>
</list>
</t>

</section>


<section title="Resource Pooling Activation/Deactivation (SCTP_RP_ON_OFF)">

<t>This socket option activates or deactivates Resource Pooling (RP) when using CMT. The sctp_assoc_value structure is used to specify the association for which the RP state should be changed and the new RP state. Note, that CMT usage itself has to be turned on separately by using the SCTP_CMT_ON_OFF option.</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 RP state should
 be changed. Ignored for one-to-one style sockets.</t>
 <t hangText="assoc_value:">
  <list style='hanging'>
   <t hangText="0">Turns RP off.</t>
   <t hangText="1">Turns RP on.</t>
  </list></t>
