 18	  "SCTP is a reliable transport protocol operating on top of a
 19	  connectionless packet network such as IP.  It offers the following
 20	  services to its users:
 21
 22	  -- acknowledged error-free non-duplicated transfer of user data,
 23	  -- data fragmentation to conform to discovered path MTU size,
 24	  -- sequenced delivery of user messages within multiple streams,
 25	  with an option for order-of-arrival delivery of individual user
 26	  messages,
 27	  -- optional bundling of multiple user messages into a single SCTP
 28	  packet, and
 29	  -- network-level fault tolerance through supporting of multi-
 30	  homing at either or both ends of an association."

 33	  module will be called sctp. Debug messages are handeled by the
 34	  kernel's dynamic debugging framework.
