SCTP Parameters - RFC 2960
(last updated 2001 June 08)
"Stream Control Transmission Protocol (SCTP)" defines extensible
lists for SCTP Chunk Types, Chunk Parameter Types, Error Causes
and Payload Protocol Identifiers. New chunk types are assigned
by the IANA through an IETF Consensus action as defined in
[RFC2434]. IANA registry of these parameters is listed here.
CHUNK TYPES
ID Value Chunk Type Reference
----- ---------- ---------
0 - Payload Data (DATA) [RFC2960]
1 - Initiation (INIT) [RFC2960]
2 - Initiation Acknowledgement (INIT ACK) [RFC2960]
3 - Selective Acknowledgement (SACK) [RFC2960]
4 - Heartbeat Request (HEARTBEAT) [RFC2960]
5 - Heartbeat Acknowledgement (HEARTBEAT ACK) [RFC2960]
6 - Abort (ABORT) [RFC2960]
7 - Shutdown (SHUTDOWN) [RFC2960]
8 - Shutdown Acknowledgement (SHUTDOWN ACK) [RFC2960]
9 - Operation Error (ERROR) [RFC2960]

11 - Cookie Acknowledgement (COOKIE ACK) [RFC2960]
12 - Reserved for Explicit Congestion Notification [RFC2960]
Echo (ECNE)
13 - Reserved for Congestion Window Reduced (CWR) [RFC2960]
14 - Shutdown Complete (SHUTDOWN COMPLETE) [RFC2960]
15 to 62 - reserved by IETF
63 - IETF-defined Chunk Extensions
64 to 126 - reserved by IETF
127 - IETF-defined Chunk Extensions
128 to 190 - reserved by IETF
191 - IETF-defined Chunk Extensions
192 to 254 - reserved by IETF
255 - IETF-defined Chunk Extensions
