All SCTP RFCs Chart

All the up-to-date RFCs can be found at : http://www.rfc-editor.org/rfc-index2.html
Here, I have listed only the current SCTP RFCs and their inter-dependencies (As on June 14, 2012).
As the name implies, INFORMATIONAL RFCs are better than the PROPOSED STANDARD RFCs to understand the protocol !
RFC 4960 is the latest SCTP PROPOSED STANDARD RFC.

Definitions :
--------------
RFC  = Request For Comments
SCTP = Stream Control Transmission Protocol
