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.
