1.  Introduction

   This draft describes extensions to the SCTP sockets API (see
   [RFC6458], [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
   [I-D.tuexen-tsvwg-sctp-multipath], [Globecom2010], [PAMS2012],
   [Dre2012], [PAMS2011], [SoftCOM2011], [ConTEL2011], [AINA2010],
   [IAS2006]).

2.  Concurrent Multipath Transfer and Resource Pooling Activation/
    Deactivation (SCTP_CMT_ON_OFF)

   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.

   Definition of the sctp_assoc_value structure:

   struct sctp_assoc_value {
      sctp_assoc_t assoc_id;
      uint32_t     assoc_value;
   };

   assoc_id:  Holds the identifier for the association of which the CMT
      state should be changed.  Ignored for one-to-one style sockets.

   assoc_value:

      0  Turns CMT off.

      1  Turns plain CMT-SCTP on.  No Resource Pooling is applied.

      2  Turns CMT-SCTP on.  CMT/RPv1 Resource Pooling as defined in
         [AINA2010] is applied.

      3  Turns CMT-SCTP on.  CMT/RPv2 Resource Pooling as defined in
         [ConTEL2011] is applied.

      4  Turns CMT-SCTP on.  MPTCP-like Resource Pooling as defined in
         [SoftCOM2011], [ConTEL2011], [PAMS2012] is applied.

3.  Testbed Platform

   A large-scale and realistic Internet testbed platform with support
   for the multi-homing feature of the underlying SCTP protocol is
   NorNet.  A description of NorNet is provided in [PAMS2013-NorNet],
   [ComNets2013-Core], some further information can be found on the
   project website [NorNet-Website].

4.  Security Considerations

   Security considerations for the SCTP sockets API are described by
   [RFC6458].

5.  IANA Considerations

   This document does not require IANA actions.

6.  Acknowledgments

   The authors would like to thank Michael Tuexen for his support.
