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

51 If you say Y, this will enable debugging support for counting the
52 type of objects that are currently allocated. This is useful for
53 identifying memory leaks. If the /proc filesystem is enabled this
54 debug information can be viewed by
