It offers the following 21 services to its users: 22 23 -- acknowledged error-free non-duplicated transfer of user data, 24 -- data fragmentation to conform to discovered path MTU size, 25 -- sequenced delivery of user messages within multiple streams, 26 with an option for order-of-arrival delivery of individual user 27 messages, 28 -- optional bundling of multiple user messages into a single SCTP 29 packet, and 30 -- network-level fault tolerance through supporting of multi- 31 homing at either or both ends of an association." 32 33 To compile this protocol support as a module, choose M here: the 34 module will be called sctp.
