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

this option to gather detailed trace information

If you say Y, this will enable debugging support for counting the

type of objects that are currently allocated. This is useful for

identifying memory leaks. This debug information can be viewed by
