16 Stream Control Transmission Protocol
17
18 From RFC 2960 <http://www.ietf.org/rfc/rfc2960.txt>.
19
20 "SCTP is a reliable transport protocol operating on top of a
21 connectionless packet network such as IP. It offers the following
22 services to its users:
23
24 -- acknowledged error-free non-duplicated transfer of user data,
25 -- data fragmentation to conform to discovered path MTU size,
26 -- sequenced delivery of user messages within multiple streams,
27 with an option for order-of-arrival delivery of individual user
28 messages,
29 -- optional bundling of multiple user messages into a single SCTP
30 packet, and
31 -- network-level fault tolerance through supporting of multi-
32 homing at either or both ends of an association."
33
34 To compile this protocol support as a module, choose M here: the
35 module will be called sctp. Debug messages are handled by the
36 kernel's dynamic debugging framework.
37
38 If in doubt, say N.

46 If you say Y, this will enable debugging support for counting the
47 type of objects that are currently allocated. This is useful for
48 identifying memory leaks. This debug information can be viewed by
49 'cat /proc/net/sctp/sctp_dbg_objcnt'
