| 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. Debug messages are handled by the | |
| kernel's dynamic debugging framework. | |
| If in doubt, say N. | |

| help | |
| 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 | |
| 'cat /proc/net/sctp/sctp_dbg_objcnt' | |
