This patch implement sctp association probing module, the module
will be called sctp_probe.
This module allows for capturing the changes to SCTP association
state in response to incoming packets. It is used for debugging
SCTP congestion control algorithms.
Usage:
$ modprobe sctp_probe [full=n] [port=n] [bufsize=n]
$ cat /proc/net/sctpprobe
The output format is:
TIME ASSOC LPORT RPORT MTU RWND UNACK <REMOTE-ADDR STATE CWND SSTHRESH INFLIGHT PARTIAL_BYTES_ACKED MTU> ...
The output will be like this:
9.226086 c4064c48 9000 8000 1500 53352 1 *192.168.0.19 1 4380 54784 1252 0 1500

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.
