| 14 | Stream Control Transmission Protocol | |
| 15 | ||
| 16 | From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>. | |
| 17 | ||
| 18 | "SCTP is a reliable transport protocol operating on top of a | |
| 19 | connectionless packet network such as IP. It offers the following | |
| 20 | services to its users: | |
| 21 | ||
| 22 | -- acknowledged error-free non-duplicated transfer of user data, | |
| 23 | -- data fragmentation to conform to discovered path MTU size, | |
| 24 | -- sequenced delivery of user messages within multiple streams, | |
| 25 | with an option for order-of-arrival delivery of individual user | |
| 26 | messages, | |
| 27 | -- optional bundling of multiple user messages into a single SCTP | |
| 28 | packet, and | |
| 29 | -- network-level fault tolerance through supporting of multi- | |
| 30 | homing at either or both ends of an association." | |
| 31 | ||
| 32 | To compile this protocol support as a module, choose M here: the | |
| 33 | module will be called sctp. | |
| 34 | ||
| 35 | If in doubt, say N. | |
