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
Daniel Borkmannbb333812013-06-28 19:49:40 +020033 module will be called sctp. Debug messages are handeled by the
34 kernel's dynamic debugging framework.

44 This module allows for capturing the changes to SCTP association
