1.  Introduction

   This draft describes extensions to the SCTP sockets API (see [2],
   [1]) 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 [3], [10], [5], [4],
   [7], [6], [8], [9], [11]).

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 [9] is applied.

                 3  Turns CMT-SCTP on.  CMT/RPv2 Resource Pooling as
         defined in [8] is applied.

                 4  Turns CMT-SCTP on.  MPTCP-like Resource Pooling as
         defined in [6], [8], [5] 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 [12], [13], some
   further information can be found on the project website [14].

4.  Security Considerations

   Security considerations for the SCTP sockets API are described by
   [2].

5.  IANA Considerations

   This document does not require IANA actions.

6.  Acknowledgments
