Introduction [RFC4960], which currently defines the Stream Control Transmission Protocol (SCTP), provides a procedure to define new chunk types. However, several protocol extensions currently being discussed need to define new chunk flags for existing chunks. This document updates RFC 4960 to overcome this limitation. It defines the procedure to register chunk flags and specifies the registry entries for existing chunk types. The protocol is notShow full document text
