[Tsvwg] SCTP stream EOF

[Florian Niederbacher <[e-mail]>]

Hi,
I would ask what are you thinking about a definition for an EOF on 
streams in SCTP. My problem is that I would need a signaling method to 
report an EOF without closing the whole SCTP association. If I am right, 
socket connections get only an EOF if the connection will be closed (no 
sending of EOF on socktes in another way is possible). In 
draft-stewart-tsvwg-sctpstrrst-00 the possibility the reset of streams 
is discussed. This would also be a solution if you can check the 
numbering sequence in User Space.
A proposal would be to generate an SCTP_EVENT e.g. SCTP_STREAM_EOF to 
signal EOF on streams. In this way you can stop receiving and also reuse 
the stream or at least continue in multi-streamed network applications, 
if you use different threads or processes for the receiving procedure on 
streams. Maybe an other possibility exists to signal an EOF on SCTP 
streams, but at the moment I can't find any solution to deal with this 
problem. What are your proposals and comments?

Best regards
