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.

43 This module allows for capturing the changes to SCTP association
44 state in response to incoming packets. It is used for debugging
45 SCTP congestion control algorithms. If you don't understand
46 what was just said, you don't need it: say N.
