| | 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. Debug messages are handeled by the |
| | 34 | kernel's dynamic debugging framework. |
| | 35 | |
| | 36 | If in doubt, say N. |
