Introduction 63 This draft describes extensions to the SCTP sockets API (see 64 [RFC6458], [RFC4960]) which allow an application to configure the 65 behaviour of the Concurrent Multipath Transfer (CMT) extensions CMT- 66 SCTP, CMT/RPv1-SCTP, CMT/RPv2-SCTP and MPTCP-like (see 67 [I-D.tuexen-tsvwg-sctp-multipath], [Globecom2010], [PAMS2012], 68 [PAMS2011], [SoftCOM2011], [ConTEL2011], [AINA2010], [IAS2006]). 70 2. Concurrent Multipath Transfer and Resource Pooling Activation/ 71 Deactivation (SCTP_CMT_ON_OFF) 73 This socket option activates or deactivates CMT and sets the 74 corresponding Resource Pooling variant to be applied. The 75 sctp_assoc_value structure is used to specify the association for 76 which the CMT state should be changed and the new CMT state. 78 Definition of the sctp_assoc_value structure: 80 struct sctp_assoc_value { 81 sctp_assoc_t assoc_id; 82 uint32_t assoc_value; 83 }; 85 assoc_id: Holds the identifier for the association of which the CMT 86 state should be changed. Ignored for one-to-one style sockets. 88 assoc_value: 90 0 Turns CMT off. 92 1 Turns plain CMT-SCTP on. No Resource Pooling is applied. 94 2 Turns CMT-SCTP on. CMT/RPv1 Resource Pooling as defined in 95 [AINA2010] is applied. 97 3 Turns CMT-SCTP on. CMT/RPv2 Resource Pooling as defined in 98 [ConTEL2011] is applied. 100 4 Turns CMT-SCTP on. MPTCP-like Resource Pooling as defined in 101 [SoftCOM2011], [ConTEL2011], [PAMS2012] is applied. 103 3. Security Considerations 105 Security considerations for the SCTP sockets API are described by 106 [RFC6458]. 108 4. IANA Considerations 110 This document does not require IANA actions. 112 5.
