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. 36 37 If in doubt, say N. 38 39config SCTP_DBG_MSG 40 bool "SCTP: Debug messages" 41 depends on IP_SCTP 42 help 43 If you say Y, this will enable verbose debugging messages. 44 45 If unsure, say N.
