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
