SCTP SHUTDOWN COMPLETE chunk


The SHUTDOWN COMPLETE chunk is sent, by the originating host of the SHUTDOWN, in response to the SHUTDOWN ACK chunk. It is sent to acknowledge that the association is finally closed.

Type - bit 0-7. Always set to 14 for SHUTDOWN COMPLETE chunks.

Reserved - bit 8-14. Not used today. Might be applicable for change. See SCTP Common and generic headers for more information.

T-bit - bit 15. The T-bit is not set to signal that the sending host had a Transmission Control Block (TCB) associated with this connection and that it destroyed. If the T-bit was set, it had no TCB to destroy.

Length - bit 16-31. This is always set to 4 for SHUTDOWN COMPLETE chunks, since the chunk should never be any larger, as long as no updates to the standards are made.
