It offers the following 22 services to its users: 23 24 -- acknowledged error-free non-duplicated transfer of user data, 25 -- data fragmentation to conform to discovered path MTU size, 26 -- sequenced delivery of user messages within multiple streams, 27 with an option for order-of-arrival delivery of individual user 28 messages, 29 -- optional bundling of multiple user messages into a single SCTP 30 packet, and 31 -- network-level fault tolerance through supporting of multi- 32 homing at either or both ends of an association." 33 34 To compile this protocol support as a module, choose M here: the 35 module will be called sctp.
